Has anyone here installed or know of anyone with highlifters big bore kit for a forman 450??? It looks like a nice kit, 40 over sleve, 40 over high compression piston, gasket kit and matching cam. Just wondering if anyone can voutch for the benefits of the kit. I already have a K&N filter, jets are readilly available, so I'd probably install a supertrap muffler too.

Also, what cc would you end up with with the 40 over kit???

Thanks
