    Drop in Cams

    What is the best drop in cam for a 400 without the expense of getting new hardened rockers.:devil

    as far as the best i dont know. But i put a midrange drop in by WebCam in mine, and i like it real well, good power increase all around really. It is like 175 plus 160 refundable core charge i think.

    I know alot of people use the xr400 cam. What are it's advantages and how does the bike feel afterwards. Is it that big a difference. What about Honda's HRC cam. Its supposed to be a factory racing cam for the XR400 what could I expect from it?

    Honda Guy I got my harden rockers from WB and I think that TC does have a cam but I dont know how much it is.

    mosley I hear that the HRC cam is a good drop in but it cost more than the 451 Web cam. Im not sure how much of a difference there is between the two but im sure they both are better than the stock cam.

    The xr cam is a good all around cam. It is a fairly mild modification, but it will wake up a 400ex quite a bit. The HRC cam is more radical, and from what I have heard, it is more of a mid to top cam, and your bottom end won't be as strong. I don't know how much truth there is to that.

    Yes TC has Two Cams. He has a XC and a MX Cam. The XC adds Bottom End and the MX is for all around Power. I think it hits best in the Mid. The XC is $179 and the MX is $209. They do not need Heavy Duty Valves or Hardened Rockers.

    Does TC use JE pistons? how much would it cost to get TC to put in a 416 pistion(bore) and a MX cam? Is there anything eles he usually does, I dont want to do the head work yet. Will the TC mx cam have alot more power then a XR cam?
