i doubt that tom will do just a bore and cam motor... i think when they do engines they like to do the full deal with porting and everything... yes i think the tc cam makes a differnce over the xr400 cam

I think TC uses Wiseco Pistons. You could get a JE 416 Piston and put it with a TC MX Cam. I would Call Tom and ask to make sure. I`m sure his Piston Kit would be Great. The TC Piston Kits are $120 I think and the MX Cam is $205-$210. You are looking at $330 or a little more. Then I would get some Viton Valve Seals. I think those are around $10. The it`s just having the Piston and Cam put in unless you are going to do it yourself.

ABERCROMBIE PREPPY RIDER!
I am getting a Hot Cams as soon as they are in stock. They are brand new cams, not regrinds of used cams. There is no core refund either. They are made out of billet aluminum so they are the same hardness as the rockers so there is no need the harden the rockers or get new valve springs. They have a Stage 1 and 2 available for the 400ex. I am gonna get the stage 2. Best part is they are only $132.99 for a brand new cam through Dennis Kirk. They are expecting delivery on them in early may. Hot Cams is a partner of Pivot Works so they are definately quality parts. They have also been extensively tested. I will post their phone nuber in a sec....

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