I got an 89 250r mildly worked. it runs real strong in the top end rpms can harldy keep the front wheels on the ground :-) .

anyway on the low end it seems to run rough . I know the hole 2 stroke power band thing . but this is either running 60mph . or running rough..lol

what can this be ? plug is new . temps are in the 20s and 30s .

jetting ? if so which one . ? I am getting some spooge out of the silencer. thanks for any help

Seems to me your rich on the bottom end. I would lower the needle one notch and see if that helps.
