misfire

Although my Vmax runs great, I have noticed that when starting from cold, the rear right cylinder has a slight 'misfire'. After idling for a minute it disappears as soon as it starts to warm up. I have also noticed that when the bike starts to get low on fuel it also starts to miss on the same...

Hi all, I've tried lots of things listed in these great forums related to this problem I'm having... but still some issues :bang head: The bike runs perfect for the first 5 mins of the day... then when it's warmed up it starts backfiring/misfiring. The exhaust note also changes - sounds...

Got my leaking exhaust fixed....sorted out the popping etc very well, Bike has always suffered from misfire when warmed up...UFO 4 into 2 Slash Cuts full system fitted

Bike has UFO StreetPro 4into 2 fitted, even after tightening up exhausts etc it again started misfiring and has cut out when stuck in traffic for a while and temp gauge rises..standard carb / filter setup.

Hi fellas, I posted a while back about an overflow situation on one of my carbs. Got that sorted out with the help of some of the good folks here. Now I have a similar symptom but a different outcome while riding. At lower speeds and gears the bike seems to run very well but on the Highway in...

I figure you guys can narrow this down. The bike starts great when cold and runs fine. It seems the longer it runs and the hotter it gets, the worse it runs. It has been starting to misfire when hot more and more, and before I dig in, I would like some hints from the experts. I am suspecting a...

This has GOT to be good news for all Vmaxxers with bad starting or hot starting issues. My Vmax would sometimes start first button from cold but often would require several long cranks - together with grinding starter clutch noises before firing. If run hot, the motor would misfire at low...

OK I cannot really say solved with a 100% due to rain, but I know it is. Well I have had the idea in my head that its caused by a short and not the carbs, and that's thanks to you all for the tips! Well earlier in the day I happen to spot some wires that were taped up and to me looked...

hey everyone, im having a very strange misfire at idle. it seems to do it only when im in traffic and the temp guage is about 3/4 of the way to hot. ive cleaned and synced the carbs, twice and im starting to think maybe i have an ignition box thats beign affected when its hot. it also sounds...

i recently swapped over to cops in my 05 using a harness that i bought off here. dont remember who (but it had the resister) the coils came from an 07 gsxr 750. first i wired up the front cylinders backwards and realized something was wrong when it backfired stupid loud a couple times( common...

I am not sure if this is the correct place for this post but here goes I thought I had all of the problems worked out with the carbs Has anyone ever experienced sputtering severe misfiring and hesitation after the motor becomes hot enough for the fan to come on? I drove home on a cooler day...

I have an 89 Max, all stock as far as I know I run 93 octane only in it (Not sure if that's important info or if it even needs to run 93 octane). Here's the problem, when it is cold or warm but not quite up to full operating temperature she runs beautifully. Now once she warms up fully she...

Greetings. I have an '85 Vmax, with a '96 engine, kerker 4-2-1 exhaust (I think), and Stage 7 kit with alloy tubes replacing the V-boost. It starts easy, runs smooth, pulls fantastically through the revs and gears. However, if I gun it hard, after it pulls like a freight train and I back it off...
