    Cam And Piston

    I ORDERED MY STOCK BORE 12.5 TO 1 PISTON AND GT THUNDER CAM TO INSTALL NEXT WEEK WITH 3 ANGLE VALVE JOB AND PORTING. DOES ANYONE ON HERE RUN A GT THUNDER CAM AND IF SO HOW DO YOU LIKE IT? DO YU THINK IT IS BETTER THAN A XR400 CAM?:devil

    from all I've heard people are having good luck with it... It's more aggresive than the XR400 cam, but given the fact your going for a 12.5 to 1 piston, I'm guessing aggressive is what your going for

    You know the world is going crazy when France is accusing the US of arrogance, and Germany doesn't want to go to war.

    I have the GT Thunder cam and race porting.I used the 10.5:1 piston though.I love this set up...I have plenty of power all over the place.It is still easy to wheelie and makes plenty of power mid to top also.I can't do a comparison to the XR cam,but from what I hear that would be my next choice for a cam if I didn't have mine.Jim
