I have a 2005 yamaha fz6 that i have owned since june. since october we have been having low temps in the range of 20-40 degrees. These temperatures seem to affect how the bike idles when it is warm. i wouldn't call it a misfire, but the idle sounds like it goes up and down slightly when in neutral, with occasion putt noises from the exhaust. if i rev in neutral and hold it their say at 4000 rpm's their will be the same putt noises, yet when in gear and riding i hear no such noises. i have also lost about 7-8 mpg's.
i took it to the dealer and the mechanic who owns a 2006 fz6 himself said the bike ran just like his and couldnt find a misfire or anything wrong, he said throttle sync was dead on. he said these bikes weren't made to sound consistent when idling or reving in neutral. just to make sure everything is running right i performed the following:
****
seafoam in tank(actually made it run worse on old plugs.)
new spark plugs
air filter
flush tank and clean sock on pump--had practically no build up
throttle body sync
pump pressure is at 42 psi
cylinder leakdown is within 8-10%
****
i am wanting to know your opinion if this is normal for how it will run in winter or do you think their may be a problem. does your bikes sound this way
ultimately i want to get a set of two brothers, but i don't want it to sound like crap because of a problem.
