2004 Honda CRF

Other

Held bike in the rev limiter before i last shut it off until that it ran fine, now i cant get it to start, ive had the valve cover off and cant see anything broken on top of the head as far as springs and cam. The bike has compression and is firing and it will turn over so it is not locked up and it is in time. It has never had valves put in it so i think thats what it needs ive shimmed them over and over and cant get any luck, as far as work done to it it has a wiseco 13.5-1 piston , stage 2 hotcam, barnett clutch basket, 6 spring pressure plate, full fmf system powerbomb header factory 4 silencer, renthal handlebars and chain, good sprockets front and back, couple peices of extra plastic and few electrical parts. Im selling it as is
