here check out this site. I will be putting one of these on to help keep me motor a lot more cooler and its supposed to be giving off as much power as a pipe kit. phatheadracing.com Its really interesting. And i think that they have a product out for the banshee but its probably something like cool heads. But anyways this is what that supposed to be and it has changable dome so im going to put a high compression dome and lose some top end but climb in 3 maybe 4th gear which is pretty fast on a dirtbike.

 

my son makes it up comp hill at dumont on is rm65. it is highly modded but it makes it even with just a 12" paddle.

 

how big is comp hill compared to choke cherry and what kind of mods do you consider extremely modded. I know i sound like a noob asking how big is comp hill but theres a comp hill at buttercup and numerous hills that people call comp hill.??

 

i think comp is 580 ft. do a search on the net there is pics out there. his bike has pro circuit works header and shorty tip, wiesco piston rings and roler bearings, amsoil air filter, v-force reeds, scary fast power now valve, renthal rear sprocket, rejetted. outher stuff like bars and graphics but nouthing else i can think of that would help the performance. its fast! he beats some 85s

 

Comp hill at Dumont is pretty tall but it's easier to climb than Choke Cherry, not as steep and tighter sand.

 

see the yz is gonna have more mods than that, but speeedy i got one more question how do those powner now valves work? Are they good? and where in the hell do they go they confuse the hell out of me.
