hi y'all I'm new the forum i just recently purchased a 2009 Znen zn50qt i got it knowing that it had a few issues it never really liked to start when it was cold when it did start it ran fine but after a few weeks it started lose alot of power going up hills from 25-30 mph down to 15 which could get a bit scary so i went onto eBay and purchased a complete big bore kit and it came with no instructions torque specs or anything needless to say it gave me no issue at first but it lost compression due to i believe my overtightened of the head bolts and cam keeper which might have cooked the head gasket it was still being a pain to start still but then when it warmed up and i shut it off it wouldn't start again now that i read here about torque specs so after complaining to the seller he helped me out immensely by sending me another big bore kit but i am a little nervous about the install i have been doing alot more research and hopefully some friendly tips would be appreciated thanks folks
