alright first off here is what all i have done to it to try and fix it. rebuilt top end with a bore of .60 over with a wiseco piston, dynojet jet kit, new cdi box, uni air filter, fmf fatty exhaust w/ fmf powercore 2 silencer, and boysen power reeds. it started out just bogging down so i started to check things and fixing things and it got better then got worse and now it wont even fire anymore. i am lost on what to do next. PLEASE HELP!! thanks

 

Might have more luck at getting a good answer if you specified what "it" is.
Since you say "Boysen Reeds" and "Piston" instead of pistons,,May I guess a Blaster?

 

???????????? What machine sir???????????????????????

 

...topic summary blaster won't start.... so im assuming blaster

 

yes it is a blaster
