Today i just put in a new piston in my blaster. We ran it most of the day today, and we let it break in. now tonight i went out to ride, and it won't start up. It started up and i gave it throtle...and let it warm up. then i let it idle and it died. now it wont start up. i need help please

thanks
ryan

 

Your motor was probably running lean. Since cold air is denser than hot air, more air was going into your engine with the same amount of fuel. IT IS VERY cold out tonight, so that would appear to be your problem.

try a new plug,if that dosnt work do a compression test.you may not have torqued the bolts goodor blew a gasket.

you did mic your cylinder bore right? because you just dont throw a new piston in unless you want seizure.
