i have a '06 yamaha ttr230. it was running fine a couple weeks ago and now it just started misfiring all the sudden, and occasionally backfiring. i replaced the sparkplug and that didnt really help at all. i noticed it got a little worse after i changed the oil, could there be a connection there? i really need to figure this out. thanks for the help.
p.s. - it only really does this when accelerating particullary at high rpm's. never at idle and it seems to do it when the throttle is in a certain position aswell.
