I've just pulled the top end off my yz250 and I'm looking for some feedback on how it looks to be running.
I'm thinking it's running rich although it feels really good to ride and minimal smoke and no spooge from the exhaust.
Also looks like the rings are well past their use by hours.
Bike is completely stock except for dep standard length silencer, run around sea level with 40:1 silkolene comp 2 premix with 98 ron pump fuel, no ethanol.
I was thinking of dropping the needle one clip, would this work or should I switch out some brass as well?
