2006 honda trx450r

I have a 2006 honda trx450r it has been in 4 different mechanics hands and they all tell me its fine until i get it home. first i had sent it out for new rings, and valve stems re-adjusted and replaced then he told me there was an electrical issue other than paying 60$ per hour for him to figure it out i decided to take it and figure it out in my own hands. it will start and will idle but if you kick it into gear it dies, if you hit the trottle hard it dies i've checked valve clearances and they look good i noticed some stab holes in my wires that come from the cdi box from them testing it with a multimeter could that be the problem? how would i troubleshoot that?
