I flogged the same DOHC 8 valve twin for a million years and finally got bored with it.So I got a 200 Blaster which is a 6 speed,air cooled and counterbalanced, understressed engine.I trenched the cases for a 4mm stroker crank,freshened up the entire motor,ported the cylinder,added Boyeson ports to the intake,Wiseco piston and forged clutch basket,VForce4 carbon reeds,billet intake manifold,36mmTM Mikuni.I will start with the stock pipe,all cut up to fit the bike and a few tricks I want to try to it[the pipe].If my exhaust doesn't work I will put a Jemco on it.
