Doubtful that the crank and rod was bad. Hot Rod and Weisco are very reputable. It came as a unit, right?

 

But at the risk of sounding like an @$$hole, your problem is you dumped a crapload of engine work into a 350 Raptor. You would have been better off selling the bike and investing the additional money into a Z400 or a 400EX. You didn't even try the basic stuff, like a good pipe, jet kit and aftermarket filter to get more power first. Do the essentials before cracking open a perfectly good, new motor.

Good luck with finding and fixing your problem, but I hope there is a lesson to be learned here.[/quote]

Gonna have to agree with him, why f*ck around with it when its brand new and running fine?

 

Umm the reason he tore it apart was because it blew up... And that motor was ran very very very... hard... trust me... I know.lol. Destroying that raptor was a group effort.lol. Yfzrydermace and 396ryderzech will both agree on that...
