I want more power out or my rapor. I have all the suspension mods and all of the other goodies you can see some of what I have below. Now the question is what kind of power can I expect out of high comp piston and cam compared to a big bore? I was thinking 720 cuz I figured if I am going to go in I am going to do it to the fullest.

I also want to know reliability and the best combo's as far as cam and piston and if I need springs and new rockers? Please give me some info. Everybody who is knowledgeable please give me your opinion and facts on what you have seen or know. Thanks

 

cant answer for raptor720, but I went for a trinity imitation (same parts did the work or most of it ourselves) only went with the 102mm piston (11:1) which does not need a sleeve, as I understand it there are problems with the 105mm (720)if not done properly, I got the webcam race profile cam 80-421 which is their most extreme cam, I put in a set of rd springs (cost more than the cam), and did a polish and port. this gave me great mid to top end but cut back on the low end, the webcam 80-411 would probably been a better choice for more low end. In the flat out my buddies cant keep up, but by now they have figured out that in the tight turns and twists where I have to drop my rpms they can catch up. for the most part it is wicked fast, I have no dyno but I figure I am in the 60hp range (k&n filter with open airbox sure help), I only have about 10+ hours on the motor so no info on reliability
