I'm experiencing alot of compression when pull starting, at times its so much it pulls the bike off the ground. but when I get it started it runs great. any ideas? I added the .265 lift cam and flat top piston. Its also spitting fuel out the carb at times when pull starting. I thought it might be the valve lash but I checked it and its fine. The cam has a compression release so I would think that would help this not happen, is there a point where you get too modified to where you have to have a starter?
