stuttering fzs 600

[ade the blade]

thanks ade...just what i need....a kick up the backside...........my wifes fed up with flushing the loo with a bucket and bathing in the front room using my grandads old tin bath.......good for me though as nothing worth watching on the telly 

if she farts, run like hell as you could have your own personal tsunami !! :lol :lol :lol

ade....you`ve met my wife then 

[ade the blade]

ade....you`ve met my wife then 

no, but i know the difference between distant thunder and a galvanised fart !! :lol :lol

[red98]

ade ,god help you if my wife reads this post.....made me laugh though  :rollin :rollin :rollin :rollin

[red98]

ok...enough of this farting about....had a bit of a balls up today....went straight out to the garage tonight and removed the carbs from the fazer,35 mins from start to finish,put the two next to each other and compared the sliders,not much between them so i thought i would swap the pipes in readyness to fit the new carbs tommrow night all went well untill i noticed the fuel supply pipe was in the wrong position and needed twisting round a bit so i released the clip and turned it with my hand......thats when the t peice broke  :eek .  to replace this means separating the carbs and iam not doing that so the only option i have is to swap all the internals,sliders,needles,jets and emulsion tubes,i`ll keep the origanal diaphrams as they look better than the new ones.unless i can fine some cheap pattern ones...........oh the joys of fazer ownership   
on the up side the new carbs were well pitted and had seen a fair few winters mine are bright and clean as iam a pansy and dont ride in the winter

:rolleyes :rolleyes :rolleyes :rolleyes always one, ya bozo. only kidding. good luck with the innards. hey,would sliders etc be classed as carb offal like chitterlings and tripe ? :lol :lol

[red98]

just did`nt want you to come to any harm,you`ve been a helpful chap and the wife`s a big unit......i mean a delicate little thing......

[red98]

at last a bit more work on my fazer...today i stripped the secondhand carbs and fitted the sliders,needles, main and pilot jets,used my diaphrams as they look good and the seconhand ones were a bit mis-shaped and not as flexable as mine,slid the carbs back into position and tightened up the clips around the inlet rubbers,thats when i sheered one of the bolts,not going mad the heads in excellent condition not chewed at all,sheered just below the head of the screw (metal fatiuge ?) m4 x25mm,could not find any in my parts bins so will see what b&q have in the morning,probably best to replace all 8.....update tommrow

[red98]

got the screws from b and q this morning,£3.57 for ten,could only get slotted so replaced just the one for now,air box bolted back in place and battery re-fitted.pressed the start button and a few seconds later the bikes running again,i swapped over the tps as well so i adjusted that so it read 5000 rpm on the rev counter,connected up the gauges to balance the carbs,not to far out but runs a lot better now they are spot on,hard to get to the adjustment screws but with a long slim posi screwdriver and a torch the job went well,well worth doing...i need to fit the stainless downpipes i bought off DEADEYE but i want to clean them up a bit first, iam going to use autosol and some fine wet and dry, need to buy these as right out at the moment so test ride will be next weekend now,it starts better now hardly turning over and has better pick-up

Hey, I had the same sort of thing a few months back, I dicked about with loads of things and the one day I replaced the air filter ( which wasn't that old, hence I hadn't changed it earlier ) but also I looked at this bit

http://foc-u.co.uk/index.php/topic,2849.0.html

Item 24, mine was blocked . Cleaned the tubes out etc and it was sorted.

Now it may have been just down to the air filter needing replacement and the other bit had jack **** to do with it but maybe worth a look it's a 5 min job !

hi andy,i did see that post and thought about it and then forgot about it.the air filter would have to be in a right old state to cause a stutter and i like you have a new one,so parhaps you might have stumbled accross something here,iam off to the garage now to check my tubes.....i`ll look at the bike while iam out there too  :rollin :rollin :rollin .....
will let you know shortly

[red98]

breather tubes checked last night,no problems there.....there was a post on here a while back,a chap had replaced his air filter only to have a stutter when test riding changed the filter back and all was ok its been playing on my mind for a while but cant see how it would cause a stutter...and now theres two of you !!!!!

no, i don`t believe air filter should even be considered as the prob. gotta go down the ignition / fuel routes.

bike starts and runs better now and pick-up is better,not been for a test ride yet (bloody rain)....if the carb rebuild has not solved the problem i`ll change the ecu next 

[red98]

test ride this morning  ......i`ll change the ecu next............

[ade the blade]

test ride this morning  ......i`ll change the ecu next............

never mind mate.......did carbs make any difference for you ?

[red98]

yes...balancing the carbs was well worth it....better pick-up from tick-over and smoother running
ive changed the ecu this afternoon simple job,unbolt the tail piece,remove tools,unbolt rear light,unscrew ecu,disconnect 2 block connectors....re-fitting is a reversal of removing....as they say in all good manuals 
not test ridden yet but starts and runs ok,will use it for work in the morning 

[red98]

more rain.....no test ride....iam going to bypass the fuel filter just so i can cross that off the list aswell....probably be the weekend before i get a test ride now 

[red98]

removed the fuel filter tonight and put a straight piece of tube in its place....noticed that there was too much play in the throttle and saw that the bottom lock nut on one of the throttle cables had come off and was resting on the bottom of the cable  :\ :\ ....90 mins later managed to get it back on and tight without removing the carbs again  .............test ride at weekend 

[red98]

working all weekend so no time for a test ride....so took it to work today...no change  :\ ...so tonight when i got in i put the origanal ecu back on and removed the straight tube and re-fitted the fuel filter.....i looked at the diaphrams on the replacement carbs which i thought were a bit stiff,thats the reason for not fitting them,but after a quick soak in some petrol they have loosened up a bit and returned to the correct shape,iam going to leave them to soak overnight and fit them tommrow,all being well...had a quick look at the bike and theres just enough room to replace them without removing the carbs again
