i just sent my head and cylinder to dennis for boring, porting, head milling and a piston. hes doing a mild port job so i can have good bottom end and still have good mid to top and tourqe. how much hp do u guys think i will be making? im gonna run the hpd standard clutch kit wtih the hpd red primary but what weights to i run? i thought dennis said 55 but im not sure. what quads should i be able to run with? thanks guys, scott

 

I'd stick w/ what Dennis suggests, he knows the characteristics of his porting job. If you really want accurate clutch tuning, get an Exhaust Gas Technologies, digital, recording tach. [img]i/expressions/face-icon-small-smile.gif[/img]
