NEVER SEE 130, BEST PIPES FOR THIS MOTOR WERE THE YAMAHA GYT. WITH PORTING THESE MOTORS WERE AROUND 118. I,LL SEE WHT I HAVE FOR YA. 3:16 (yammie tony)
Ya Tone if you have some documents throw em my way but would i be better off just using psi pipes with the sx motor?? That would only put me at about 110 corrrect??
You mean somthing like this motor is a 95 vmax 600 with Aaen race pipes and full race porting (can be trail ridden with different head but will still require premium fuel with octane booster) trail rode the motor for 2 years before sticking it into my 88 EX 570 oval racer porting is pretty wild boysen reeds carbs overbored and different cdi dynoed @ 132.8 at 8800 rpms with regular Aaen twins and porting will make in the 118 to 122 hp at 8-8200 rpms
