I know a 450 is fast enough for the vast majority of events but I have one coming up that is all about top speed, I was going to put a hi-comp piston and maybe a cam in to try and get a few more horses. Does anyone have any recommendations? Also looking at running VP MR12 as I will not be remapping. Any tip appreciated.

Mr12 requires a remap. to be used correctly, use t4 if you don't want to remap.

Twisted Development has a good hi comp Piston and maps.

Np man,all those don't need a remap, but the upper end fuels are blended for modded, remapped motors. To get the full effect. Mr12 is def better, but also alot more $

DCR cams for sure. Dan is making killer power on the KTM/Husky's and he has his grinds down to a science.
