Stuttering Fazer 1000

[Mick-H]

I'm having a very similar problem with mine but as yet not tried anything, it'll be coming off the road at the end of the month to get fettled by my mate at Bolton Motorcycle Workshop (yes that is a blatant plug) he's the best I know on bikes and he's pretty much saying the same as Mike re floats and jets so they will be our first port of call.
If we/he gets it sorted I'll post an update.

Thanks Mick. I hope yours is a straight forward fix over the trouble I have had with mine!

make sure you run the engine in the dark,,look for spark leaks on ht leads.

It's fixed!!!!
Ok...so interesting problems were finally identified.
Fuelling...unbelievably one of the tiny springs which tension the carb needle to the plastic housing needle cap inside the diaphragm had failed. It was snapped in two but remained on the top of the needle (luckily!) but there was no longer correct tension on the needle. This in effect allowed the needle to vibrate and jump about leading to the stutter. If you were smooth on the throttle it hardly registered but grab a handful and it reared it's head. Who would of thought it?
Electrical fault...Right hand coil. Where the two wires which attach to the coil with push clips. The wires feed back into the loom and are covered with a protective plastic cover. Once I cut the cover away approx. 2 inches along the loom I found one of the coil wires had corroded. I know it was still protected by plastic but somehow this was intermittently shorting.
It's been a journey and a half with this one and I guess it's unusual for either of these faults to occur on a Fazer ( my middle names Lucky!) but hopefully if anyone comes across a Fazer with similar problems then don't discount what I found on mine. Normal service has now resumed baiting the young guns on sports bikes and to say I am now a happie chappie is an understatement. Thanks to everyone who contributed and showed an interest in my thread. Keep it sunny side all! Cheers!

Thanks guys. It came close once or twice to a Fazer bonfire but honestly if nothing else it's a very easy bike to work on and always very satisfying to have fixed it yourself despite the blood sweat and tears! :lol
