    *HELP!*

    Hi
    I have a tt250 and when you try to give it full revs it misses and looses power. Down low in the rev range it goes fine tho. Could this be a timming or spark problem? any help would be much appreciated,thanks.

    Yep,Spark good,Air Filter is sweet,Fuel is sweet.And have given carb a good clean.
    It only misses and backfires when it is high in the revs.

    its a 2 smoker right?
    it could be a number of things, but obviously not those. looks like you might have to bite the bullet and take it to a bike mech, might just be in need of some good ol' TLC.

    Yammy TT250 is a 4 popper I think. DOHC, 4 valve.

    Sure is. I'm thinking timing/fuel issues.
    Do you realise how many holes there could be if people would just take the time to take the dirt out of them?
