Well I am woundering what jet size would be the best for my 1981 Honda 250r. What it has done,
Rebuilt engine,
.20 over weisico piston kit,
Head shaved 7 thousenths
Bigger then stock carb with spacer ( so it clears the case)
The carb is bigger then stock I know, what it came off of I dont know. The intake boot has a spacer behind it so that the carb will clear the case. I dont know how big it it. When the atc warms up it runs great but maybe with the carb jetted right it could run better. So what would be a good size jet to have in it? Thanks
