building a rodeo bike. already have lowering kit and 450r shocks.
Was thinking about installing a stage 2 magnum cam, fcr, porting the head, high compression piston.
Looking for write up and pics of the lighten fly wheel so i can show the machine shop where to take out material.
also would like to get some pics of some port work that adds mid range to top end power

my vote for any type of head work is to go to CT Racing.

Been porting 400ex heads since they came out, they know what works.

No I haven't, did u get yours together tonight? If you did, did the crank gear not mesh perfectly(have a small dead spot) when you rotated it, meshing with the counter balance gear? I have the same crank and mines doing that. Itl wear in I'm sure
