Low Rev Stuttering.

[arch33angel]

My Fazer hasnt seen much action the last few months and yesterday I went from Southend to Watford and back. When I got into Watford my bike started having problems getting away from lights and junctions. On the first three or four seconds it was stuttering and all of a sudden the power would just surge back and things were fine til I had to stop at lights or whatever and the same thing. I had to slip the clutch to make sure I didn't stall and then wham full power again. Was a bit worried on M25 on way back but the bike was fine. Seems to be ok again this morning. No problems getting away from standing start. Any ideas what happened and could it happen again? Thanks.

hey mine is doing the same 2001 model with 16k on the clock i service it myself and looking at the haynes manual it just needs brake fluid, coolant change plus swing arm regrease things i can all do myself at 16k service. My bike stutters when you blip it but is fine when its moving i went to yam dealer today and they told me to try FLC 200 which i did but it still feels the same i also noticed it sounds rough with some rattling from the engine in neutral but when you pull in the clutch this stops ?? any ideas guys ?? ive checked the plugs and they all look ok any ideas how to move forward to fix this problem ? i was going to change the inline fuel filter, check the carb balance, stuff like that any ideas will be most welcome i will try anything before i give up and give it to a dealer to fix so hopefully this forum will be my savior !!

i would start by checking tps and then parhaps balance the carbs if you have the tools

As you havent used it in a while there might just be some crap and in carbs, give it a good blast (Rev the nuts off it) for 60 miles see how it is after it.

did that yesterday valentino would have been proud of me !! it still doesnt pick up right away when you blip it it gives a very slight stutter. The thing that worries me is all the clunking and clanking when sitting in nuetral but goes away when the clutch is pulled in ?? The clutch isnt slipping and the bike goes fine when its moving it does make some strange noises when going slow and the revs are at about 2500. im going to start looking at each thing and work my way thru them the bikes a 2001 model with 16k on the clock dont know maybe if the chain and sprockets need done how long do they usually last on the fazer ?? thanks for the replys btw much appreciated and al let the forum know how i get on. cheers

I've a FZS600 2003. Since I got it, it has always idled "lumpy" riding below 3k revs was "jerking and snatching" (if that makes sense) the engine and clutch also rattled at idle. I balanced my carbs last week and now rattle gone smooth below 3k revs I can ride at 30/40mph in 6th gear and all still smooth.
 
Hope this may help.

very rewarding balancing carbs.....with an instant improvement,well worth doing 

[yambam46]

will give it a try . any idea where to get a good set of gauges then ?? cheap cheap !!
 

[red98]

i have the dial type think they cost me about £50 on ebay,i always connect each dial to no1 carb to make sure they are all reading the same before i start...theres a lot ao fans on here for the colour tune gauges who iam sure will be along shortly

Allthough I had a stutter at high revs months ago I got that sorted, But mine has just started doing the same as yours. 
 
One thing I have realised is that when pulling off form standstill if I rev it to about 3k revs first it's fine, only below 3K
It can run rough on tick over so i got a bit of water and after a few seconds of the engine running dripped some water onto each downpipe one at a time and it is No 2 cylinder not firing prperly...as the water didn't fizzle as you'd expext on a hot down pipe ( does that make sense )
 
 
So for me I know it is something to do with No 2......maybe worth a try see if it's one cylinder playing up?  I just gotta get time to balance the carbs to see if that sorts it .
