Ok so I had an 03 blaster bone stock other than DG pipe and silencer. Anywho I power shifted the tranny one to many times and blew a chunk of the casing out from what I'm assuming is broken gear. I got a bottom end from a buddy off of a running blaster and just put my top end in it and now it won't start. It ran perfect before and I never touched anything in the carb. Any help is appreciated
