What's wrong with the new one you've bought? Or is it simply a matter of you refuse to let the universe win and you are determined to get your '98 back on the road without its stutter :P

not going to be beaten by "the stutter"....when its all sorted i`ll bring it along to one of the lofo`s ride outs and you`ll see why....its a cracking looking bike

in the best colour

not had much of a chance to look at the new one yet but a quick check over last night found.......missing centre stand,bent clutch lever,broken exhaust stud,damaged thread on front sprocket shaft, no nut !!,carbs held on with cable ties

....saying that it does start and runs well with a high tick over possibly caused by the blowing exhaust and cable ties letting in a bit of air,air box side of the carbs,a weekends fettling should sort these out

Not sure if you have changed the air filter or not, but mine used to do the same thing, replaced with a k&n and no more stutter...

Hedgetrimmer · « **Reply #955 on:** 11 July 2013, 12:37:41 pm »

I think by now he's replaced everything but the tyre valve caps, but he can't remember what's been done - you'll have to start over again Paul!

red98 · « **Reply #956 on:** 11 July 2013, 01:11:20 pm »

played around with the air filter a couple of weeks ago...it did make a difference between k+n and standard but stutter still there

.....with the new bike as spares doner it does feel as if iam starting again

Cheer up mate, at least you've got the thou to play on meanwhile.

update....i now have a spares bike

....suffered the "front sprocket nut"issue and lost its nut on the M25 damaging the thread as it rattled around in the cover,thread repaired and new 12mm nut and tab washer fitted along with a new clutch lever and i was able to ride it down the road....tyres have had it but apart from that it rode very well

....so tonight ive been stripping a few parts off it to try on "the stuttering one.parts include...

carbs with tps
coils
fuel pump
ecu
[size=78%] battery,its new and iam still on the origanal one[/size]

pick up coil
clocks,as i think they work with the ecu

new parts ive fitted include.........plugs
plug caps
k + n air filter
carb to head inlet rubbers

thats it for now but i might swap the tyre valve caps ,as nick has pointed out its about the only part i hav`nt touched yet

[/size][size=78%] [/size][size=78%]

Hedgetrimmer · « **Reply #960 on:** 14 August 2013, 09:31:43 pm »

Hurry up and fix it Paul, when you're done you can start on mine!

red98 · « **Reply #961 on:** 15 August 2013, 02:40:39 pm »

think i`ll add.....regulator,fuel pump relay and started relay to that list ,cant think of anything else

red98 · « **Reply #962 on:** 26 August 2013, 11:17:13 am »

morning stuttering fans......if theres any of you left

.....i think i may have fixed it

........been swapping a few things from my spares bike,a lot of items which i have already checked/changed but also one new item which i have not touched yet,i have mentioned it in one of my more recent posts,with no replys from more knowledgeable foccers.....so thought we would have a little guessing game.............happy to supply beer tokens to the correct guess and more importantly an explaination in how this item works.......my monies on FAZERIDER being the winner...................oh..buy the way FAZERIDER....the generator and cover you kindly donated to the "stuttering one",ive used the internals on my bike and passed the cover onto DEADEYE,so a big thanks from both of us

It's like the end of an era, I almost don't want this thread to end... glad to hear you appear to have it fixed though! Looking forward to a detailed analysis

There's a trailer thread to send skywards...

Ditto on the analysis though!

Just a general observation for anybody chasing a misfire or stutter. During my investigation I cleaned my carbs, replaced my plugs, replaced fuel filter, cut back my ignition leads did a carb balance none of which did anything. My symptoms only came to light after riding the bike hard for a few miles and then she would misfire on hard throttle at low revs. I would recommend anybody who has a misfire symptom to replace the plug caps. You can get 4 NGK replacements for less than a tenner.
Another possible red herring symptom is a rough idle. I have a K+N filter and a Beowolf end can with baffle in. Even after doing all of the above my bike still doesn't idle smoothly but rides great so I'm not worrying about it.

How can you have "hard throttle at low revs"

johnboy512 · « **Reply #966 on:** 26 August 2013, 12:21:35 pm »

i am gonna say a Improperly adjusted fuel level!!!!! maybe

Maybe I didn't explain it right. After riding hard for a few miles, if I had to slow down then open up the throttle (low revs, high gear) at anything more than about 1/2 an inch then the bike would stutter/misfire. If I eased the throttle extremely gently then I could get the engine to pick normally. You can pull the throttle around hard at any revs. The gear your in will decide how fast the engine picks up.

mmmmmmmmm...good guess JOHNBOY....you are thinking the same way as i WAS

[size=78%]...........iam not 100% sure ive fixed the problem as iam limited on test ride length due to lack of tax,but on the short test ride i had after swapping parts there was a massive improvement....going to tax it at the end of the month and see for sure......will sneak out later when my private test track is quiet ......any more gusses ?[/size]

Couldnt be the pick up coil!!!!!

i think that was part to blame and did replace it with one kindly donated by FAZERIDER,the wiring where it passes through the cover was very worn....the new one did improve things......and thats a MASSIVE clue.....

johnboy512 · « **Reply #971 on:** 26 August 2013, 07:47:39 pm »

So i'm getting a tad warm mmmmm pick up coil, wiring rubbing through casing,

igh resistance on the pickup side to to the ignitor unit (white/red) wire maybe!!!! still i was with you on the fuel side with the level of the float chambers in the carb.....

red98 · « **Reply #972 on:** 27 August 2013, 07:03:14 am »

yep....very close

and with no one else playing looks like the beer tokens are coming your way..........unless FAZERIDER is going to join in

Sounding very electrical to me... unfortunately I know next to nothing about the electronics so can't really make any well thought out guesses...

Spark not strong enough?

samlj96 · « **Reply #974 on:** 27 August 2013, 10:13:17 am »

Red98, please put us out of our misery, I too got a stuttering Fazer, with the same symptoms as yours, and done more or less everything you have done and still she stutters! I am desperate now to have my bike back!
