Title: Acceleration stutter after service
Post by: dBfazer600 on 31 August 2013, 10:54:18 pm
Today I have done the following:

New:

Air & Oil Filter
Spark plugs NGK CR8EIX 4218
Cleaned front breaks all is good
Rear break seized but free enough not to drag until I can strip it down and see to it properly (new pads fitted and works as expected)

Bike is stuttering on acceleration on overtakes and when ridden hard. Had to adjust tick over as it shot up to 2.250K after service. Bike runs smoother than in the past and sounds sweet.

This has me stumped and can only think it been electrical as its intermittent.

Any Ideas boys and girls.

My token answer is....have you kinked or trapped the fuel pipe under the tank when you put it back down???

Noggy I let numb nuts do most of the work and he put the tank back on but forgot to turn the fuel tap back on so I did come to an halt a mile down the road without tools including numb nuts. Got it sorted after a phone call and he turned up with tool in hand and I let him play with my bike again.

I would expect any fuel blockages to be present at any point of acceleration but I will check it out tomorrow  ;)

My bet is on the air filter - if you still have the old one, swap them round as its only a 5-10 min job and will help to rule it out.

Stutter means checking the three main things - Fuel, Air and Spark

You haven't touched Fuel in your service so start with Air and Spark - easiest to check first is Air ;)

I will do one job at a time and start with sparks by putting old ones back in. Bike run like a dream for 30 mins with a noticable change in the power band but hay that's how it goes  :)

Perhaps the plug caps and leads could be the problem, seeing as they've been tugged at to get them out the way to get to the spark plugs, could have caused on of them to crack at the end or something giving a poor spark which you would only notice when under load/heavy load.
 
But as Deadeye said try the air filter first as it's probably easier to see if it's the problem.

What surprised me was that the nipple head of the new spark plugs needed to be removed to fit the caps.

To be honest Chris I am clutching at straws as this has never happened to me before and I am questioning everything

Daz
Title: Re: Acceleration stutter after service
Post by: Chris on 01 September 2013, 12:29:13 am
I'd go with the caps or leads as the main problem but just take your time and work through it. You'll get it fixed soon I'm sure.

What you see is what I have done although the rear break pistion has seized and i is awaiting delivery of new one has it is now causing the new pads to drag. So with is as an issue I am waiting until I have sorted it. The rear break has seriously put shivers down my spine  :eek but lesion learned.

Oil is just below top mark.

Been for a short run and the bike is de-accelerating faster than normal which the R break accounts for.

I had to take a heavy duty chisel to the R pistons so I could at least get the new pads in so I hope the break will push them back out when fitting new ones.

Update

Did one job at a time and firstly put new fuel filter on that made no difference so then fitted new spark caps and adjusted the throttle to take out the free play. I lubbed all cables a just in case they were dry. I have not had the chance to open it up but the bike now picks up better and throttle is more responsive. So tomorrow I hope to get it up to 10rpm where its been stuttering.

Stuttering was more noticeable on the OEM can but less on the new one.

Cheers Noggy  it is so sweet and engine is allot smoother with a face full of  :D :D :D :D :D

Chris please take great pleasure in been smug  :thumbup ;)

Been for a blast and the front wheel now raises its head  :b Gear changes and acceleration allot smoother. Unsure if stutter is still present as I may

have rolled off the throttle when in 3rd but all OK in 2nd. I need to take it on something like a motorway to give it a real test. But first impressions is that all is fine as I is now having some serious fun on the road :sex :lol

Thanks guys  :thumbup

Post by: dBfazer600 on 11 September 2013, 03:37:45 pm
2nd test ride and all is not as I hoped.

1st gear did not take it up to limit but is OK
2nd gear 10k rmp OK
3rd gear stutter around 10k rpm
4th gear doing 100mph and due to lack of road could not get it to 10k rpm as I was screaming ho shit ho shit ho shit then dropping two gears and whipping it round a roundabout.

Bike runs smoother lower down the rev range but is at its happiest when been ridden hard. Yet when opening the throttle hard from low revs in 3rd gear bike holds back for a second. So I am  :think thinking carb balance.

A new noise from the rear wheel is a squeak  :groan . Unsure if its the calliper or bearings so I will have a look at that later but only noticed it when going forward.

Unbalanced carbs makes it jittery at lower speeds, it's worth doing anyway if it hasn't been done for a while, but i doubt it'll be the issue with plenty of throttle?

Yep, carbs need doing but I am stumped at this one darrsi. Thing is it accelerates and rides better but its just this 10k and hard throttle stutter. It does not install confidence for overtaking  :(

I had a similar thing when i bought my bike but had a full carb strip down and clean done, and Dyno'd, and it sorted it out.
If you wanna try a quick and easy possible solution, then i would also suggest to you to try the "STP Complete Fuel System Treatment".
Use a half bottle each time over 2 full tanks of fuel and let it do its thing, i personally felt a big difference after a couple of days riding.
It costs about £15 a pop at Halfords.
It's another one of those things that will do more good than harm so i'd certainly give it a go and see if it helps?

I am going to try this but after I have tested the coils with a meter tomorrow as logic and symptoms are leading to a power leak somewhere in the ignition.

Daz
Title: Re: Acceleration stutter after service
Post by: dBfazer600 on 12 September 2013, 10:06:34 pm
The multimeter was out and this is how it went.

Both primary coils showed exactly the same reading 2.4
Both secondary coils were different one been 15.90 and other 15.66

day of the multimetre 12 Sep 13
day of the multimetre 12 Sep 13

So would the secondary coil cause the stutter? No idea  :'(

So my next step is to allow this stutter/fault develop as my knowledge of electricals consist of sticking my fingers into the wall sockets for a  :eek experience. I will try and find a source to fault find problems specific to FZS600.

Also had the breaks off to make sure they are not steadfast on operation and all is well there. SO I decided to set the load on my front and rear suspension as I is sick and tired of doing zebedee impressions in pot hole central. This one thing has transformed the bike yet again and is a more positive feel of all round comfort.

Not pissed off just getting pissed on the pop

Daz

PS if anyone knows about coils and whether they are buggard let me know as I have no clue what so ever

Title: Re: Acceleration stutter after service
Post by: dBfazer600 on 14 September 2013, 08:40:56 pm
So after testing the coil out put I decided to take it out for a run in the Peak. The stutter has now progressed to wider band of any where between 8 - 10k rpm in second gear and above.

My fuel consumption has dropped to 42mpg from 53mpg as an average. So fuel air mix?

With reading reds posts/thread there is a lot to take on and I do not have a garage, tools or space to strip the bike down. Nor do I have the equipment to do the compression tests. Therefore, I need to eliminate those jobs i can do so I can be precise in what I need my friendly mechanic to undertake to keep costs down.

Next I will be going for darrsi suggestion

Daz  :\

Before you did the service Daz, how long was it previously that you had run the bike & it was ok???
Title: Re: Acceleration stutter after service
Post by: Hedgetrimmer on 14 September 2013, 09:03:10 pm
Just re-read this thread - did you actually try putting the old plugs back in, as it reads as if you found the plug cap problem, replaced those, but didn't actually change the plugs again? Have seen several instances of new plugs being duff. And did you check/trim HT leads?

Before you did the service Daz, how long was it previously that you had run the bike & it was ok???

Bought the bike private seller in March from one 88 year old previous owner from new. Last 3 service interval as in book are 2007 at 12305m, 2009 at 16063m and 2012 at 19732m. I assume the services were done correctly.

I bought it with just under 20k on the clock which suggests its been stood more than rode. I have put 4K on the clock since getting it. Minimum outing for me is 80miles a day that is clocked up over weekends.

It fires up every time, apart from service only 2 other major incidents have happened. Bike fell on top of me as the side stand gave way due to me and after service fella helping forgot to turn the petrol tap back on and I came to a stand still.

Stuttering happens with standard and new can it has backfire twice with both cans.

Daz
Title: Re: Acceleration stutter after service
Post by: noggythenog on 14 September 2013, 09:21:23 pm
ye but i mean if the stutter happened after the service then either something you touched or changed did it.....or the service is coincedence....if you rode the bike say 2 days prior to the service & it was all tickety boo then for example it would negate the problem being anything to do with the fuel or the carbs, or lessen the likelyhood anyhow.
but if it was stood for a couple of weeks prior then maybe the service was just coincidence & the real culprit sprung whilst being layed up...
Also the fall is a major event...but was it all fine with no stutter after the fall????....what made you service it, was it after the fall that it was dodgy???

Found sat under the Idel speed adjuster screw

Yes on all accounts but I am thinking of putting all old plugs and air filter back in. Then testing I did find a piece of rubber sat on the engine that I have been trying to find out where it came from after the service.

Noggy it was fine after the fall no problems what so ever. It just happened I planned the service before the fall and was awaiting parts and a can became available. Bike was sluggish in comparison to its performance now although everyone who has rode it prior to service said it was a nice ride. Never felt it stuttering but I have only started been snap happy with the throttle.

It has to be something I have or have not done

re trace your steps & do the service again basically, re fit the old air filter if you still have it & double check the fuel pipe is all good under the tank.I'm a total spoon at mechanics & i did my service & put a k&n in, the bike was totally fine afterwards so i cant say it's something you've done as such but something you've replaced definately.
i cant see how it would make a difference but how much oil did you put in?, worth double checking you havent overfilled.

Oh foc, now that is a question - i think it was Hole Down with the plastic cover showing.but im not sure :rolleyes
but yeah these are the type of things to look at, or is there a bit of packaging still on the filter, or a leaf or bit of rag in the air intake.
with my basic knowledge i defo think it's something to do with this air filter.

Title: Re: Acceleration stutter after service
Post by: Hedgetrimmer on 14 September 2013, 10:21:10 pm
Just gonna indulge in a little thinking aloud here...
 
Ok, so stutters at 10k rpm in 3rd (for definite, maybe at those revs in other gears but not so noticeable), and also when opening throttle hard at low revs in third. So, electrics are under load in both instances. I can't say anything regarding your multimeter measurements as I don't know what they should be, but, they won't show what is happening when under load. I can't help but thinking that stutters at high revs points to electrical breakdown. Older bikes do tend to have such breakdowns more than newer bikes - just materials degrading over time - mileage not necessarily the most important factor.
Still, easiest and cheapest things first, and if that means air/fuel systems, so be it.

Post by: dBfazer600 on 15 September 2013, 05:30:27 pm
Not had time to look at the bike today. But hopefully Tuesday I will be able to eliminate the air filter and plugs as I am going to put the old uns back in.

Reading red98's STUTTERING FZS 600 a year on and got to post 555 and was gutted for the man even 12 months after the original post.

http://foc-u.co.uk/index.php/topic,2066.550.html (http://foc-u.co.uk/index.php/topic,2066.550.html)

I'm still not happy with the coils so I may purchase one and play around with em to see if performance chances. The secondary coil has to be a factor or they would be the closer readings as with the primary coil.

I is going back to REDs stuttering fzs as its turning out to be one of the best dramas I have read for a long time. Plenty of smut in it un all  :D

Picked up the parcel, got it home and like a 3 year old in a past the parcel game I went for it.

In order of unpacking:

Plastic cover off
Ignored the invoice
Cut the tape around box top
Box top off
Packing paper thrown across the room

 :stop ed in my tracks

As I peered into a large box I was some what confused of its content. My name was on the package along with the correct address. But I was well and truly stumped to find a pair of stilettos.

I is getting a divorce and changing my bank account details.

No part today

Checked filter all OK.
Fitted 2 new coils test ride and the stutter is just as prominent.
Fitted old sparks and stutter still present.

New sparks below that I am going to ensure gap is correct. Plugs are left to right 1 to 4 in the bike.

Just a stab in the dark but have you done a TPS check at all?
They make the bike jittery when they break down.
I checked mine for fun earlier and it was positioned wrong, not sure why?

Daz, not being awkward but by checking the air filter do you mean you fitted the old one & went for a spin???? Or do you mean you already chucked the old one & visually checked new one?, the guys in the know seem to think it wont be that but ive got my old one ying in the shed if you need a test subject.

I did a visual and ensured it was seated. I will be changing everything in next couple of days back to what it was minus oil and its filter (K&N oil filter and Fully synthetic shell oil)

Ran out of money because some one needed new girly shoes that cost twice as much as 2 new coils  :eek Therefore its as you say noggy elimination time.

Its OK I have played the no sex card only to be laughed at  :'( If it works for women why not men  :(

Daz i cant check right now what oil i put in but fully synth rung a bell when i seen it on this post, a recnt post by someone saying their clutch was slipping after a service with fully synth.


Ruby racing replied saying that the fully synth would be the issue.


Could your stutter actually be clutch slip????

To be truthful it didn't feel quite right around the 2500rpm mark so thought i'd check out of curiosity and was a bit peeved that it whizzed up to 10k on the test?

If it was clutch slip I would expect the bike's rev's to go sky high with no acceleration not a dip in revs then take off. Or am I worng?

It has been established elsewhere on this forum that fully synthetic oil does not cause clutch slip. That's all I'm saying on the subject!

It was just a gut feeling something wasn't quite right, and as i had TPS problems before actually changing it i knew the signs that it may not be right.
And i was correct  :D

It was all spot on when i balanced the carbs a few months ago?
And it was only about 6 months ago that i even found out it even existed!!  :lol

No its nice and smooth. It only does this when under load.

Next job is do a test on the fuel pump followed by checking all sensors and kill switches.

Didn't get round to checking everything but I did put stock exhaust back on and cleaned some real gunk from the side stand cut off switch. First test ride after degunk seemed better but still had its stutttttttttttttttttttttreeeeeeeeeeeeering head on. Test ride after old echaust going on had similar problems but seemed better than all other rides.

As an ex engineer the way we solved things like this was to stand back, scratch our head, go to the boss Mr Hammer and then wake the shit out of the machine that refused to comply with doing its job until it submitted to our demands.

To top it all I have just demolished her chocolate bar through comfort eating and I is now in the bloody dog house.

After spending 57 hours in bed due to my Gluteus Maximus spasm (yep my butt hurt like hell and i could not move) I have fitted a Air Assy and no change.

I have run out of money and I is not aloud to sell the car (she really does not understand me) I have done all the cheap options that has turned out not to be so cheap after adding them all up. Therefore I will be doing my last purchase of a Regulator and if that does not work I will consider the options.

Post by: noggythenog on 28 September 2013, 05:29:46 pm
Daz..i know the in the know opinion here is that it wont be the oil...i respect that...buuuuut...you did change it...it is still a variable...for all the price of some oil i would change it out for a different grade....if it doesnt work then drain it and keep it til next oil change but you know what that could just mean the difference between small and large money being spent.
now nobody shoot me!!! :2guns

Is it possible you can borrow a regulator from a foccer who lives locally to you prior to purchasing one ? Just thinking about you saving money in case it turns out to be something else  :\

To late mate ordered and paid for last night. Good idea though cheers.

OK took it out for a blast today and bike did not stutter all the time. I could not get it above 100mph but I was on a twisty track. The only difference is that i tended to ride at high revs between 8 and 10 and changed down gears if falling below 8. My MPG today has been 40mpg a huge drop from what I am use to of around 52.

Any how I is waiting for my Regulator and if that does not work its time to strip the bike and preform some heart surgery.

The work on the  :faz must stop.

I have been screamed at by her indoors about my man moan over the past 3 weeks about back ache which prompted me to go to the Doc's today. Doc did his thing then asked if he could manipulate my Butt  :eek . There is something called a sacroiliac joint which he first rubbed and poked. Now I is no spring chicken or have what some may call looks. Although, I found myself enjoying the relieve  :evil Then he asked me to mount the examination table butt side down. This i could not do so he asked if I would let him assist me by raising my legs  :\ He did the usual thing of rasing my legs to find my right one was duff, null and void of all strength, I took the advantage of informing the Doc that I have had several unexpected and painful meetings with the dog shelf that explained the bruises on my now naked body that he was examining. At this point he asked me to go limp and felt me then said no I need you really relaxed and limp (you dirty minded people you) So there I lay naked and limp for the Doc to place my left hand under my butt then take hold of my right hand (I is now at his mercy) then he places his hand on my right hip and rolls me back and forth as if he is rolling dough for a pretzil   :'( Then all of a sudden a loud click and my sacroiliac joint is realigned. Pain is still present but he says give it a few days. Three weeks of a dislocation and her in doors still thinks it was a man flue moment.

So no work on the bike aloud and if she asks no house work either  :lol

Up Date

Put a new air Assy on and still awaiting for the regulator to be delivered. Wired Garmin Zumo to bike. Got to have a blast today and stutter is now back around 10K. Unable to get speed past 110mph as bike seemed to hit a dead spot in 6th gear around 8K revs.

Nice breakfast and company though at CMC claycross today and yes considering purchasing a FJR1300

I still say change the oil for semi synth.....& i dont know shit about oil really....but with so much controversy over semi and fully synth and being that i think most fzs600 are run on semi synth then i think a nice little oil change for all the money it costs would be a good start.

A quick question before I need to run out of the house.

Took cabs of bike and the pics show what I have found. I do not think they are that bad but there are some concerns and need a little advice.

Pic 7 The filter in the centre of the cabs was not connected to any thing on the bike. Is this correct?
Pic 8 Second in from left screw and washer missing from chock rod. Will this be of detriment on its operation?
Pic 9 Float bowl drain screws. I can not get any of them to move. Do I need them in working order when back on bike and priming fuel?
Pic 12 Ordered new O rings as you can see with the clean gasket and dirty. I is normal ware and to be expected?
Pic 13 Diaphragm housing on carb 2 is sooted up which was not present on the first card. This sits beside the filter in pic 7. Is this normal?

How do you remove the needle from the diaphragm?

Will be stripping the other two carbs when I get back home

Thanks

Daz

quick answer.........yes
                          no....is correct
                          no
                          yes
                          no...check mixture screws
 
just peel the diaphram away,bit like removing a tyre,check for holes and splits and it is still nice and flexable....i think the needle is held in place with a top plate held in place with the big spring.

Yesterday I put the bike back together and fired her up with petrol pissing out all over the place from the carbs. This was after putting in a new K&N air filter. The bike had been run for 10 mins with rad flush in the coolant system with no signs of a leak. I then drained and flushed with 15L of distilled water. There were fine black particular matter floating in the water that eventually ran clear. It took me and my bro an hour to strip carbs off as I had a good idea why petrol was pissing out of the float bowls. It was the new gaskets so I simply put the old ones back on that did the job.

But this is what happened when taking out the carbs
1 At what point do you realise something is wrong 9 Nov 13
1 At what point do you realise something is wrong 9 Nov 13

[Limit reached]
Did I say simple?

So eventually got the clip off put old gaskets back on but use (sparingly) rubber grease to hold them in place and refit. I did prior to this use carb cleaners for cleaning the carbs  :think and I used a guitar string to ensure the fine holes were clear. Then I soaked all metal removable parts in carb cleaner for 30 mins.

So the cabs are back on the bike and home for a beer.

Got a call this afternoon from numb nuts and he says bike still fucked as he took it out as crash test dummy. I pointed out the obvious that the clip was missing and cause a vacum problem. I went round took the bike out and bloody hell the difference is amazing even with out a clip fitted so off the a spars shop and clip fitted and I is a really happy  :faz owner.

The stutter is no more.

So you're off the kebabs & comfort food now & all back to normal eh...since the bike is back, excellent!


Just a quick one though, on your most recent post you say you stuck on a new k&n, had you tried that before the carbs came off???, i mean can we be sure whether it was the carb cleanor the air filter that cured the stu tu tu tter er er?????
Title: Re: Acceleration stutter after service
Post by: dBfazer600 on 10 November 2013, 11:59:40 pm
No mate I was getting pissed of with doing one job at a time with the tank on then off. My pants don't removed as often as the tank. The filter was a last minute decision. I suspected icing was taking place as it was intermittent, up in high revs and at speed when stuttering was happening so a possible blockage on the coolant in the carbs. Air filter I took off had less than 100 miles on it but the K&N seating in the air box is second to none.

I is a happy foccer  :woot

Daz  ;)
