what should the compression check as on a 86 250r?

about 110psi give or take 5psi

thanks, my buddy says his '86 is at about 75 psi.

it should be in a shop manual but im too lazy to look, but my R is at 185psi, but i got a duncan power head, so i know you aint gonna be anywhere close to there. but i would say more then 75, if its less then 90, somethings old. if the cylinder and piston just done i would say closer to 140-150. and if used i would guess closer around 125psi. thats my 2 cents

Texas is right, if you are lower than 90-100 it is time to break out the tools. ----Or call Sore Racing of course.
