Is There Any Other Cam Than Hotcams??

[Civicssuck]

Checking it out for a friend. I have a TRX 450R and put a 03 CRF 450R cam in her.

Searched around, but it seems all you guys use is a hotcams cam. Anything else work for a 400EX??

Web cams.

They are really good camshafts.
They have three diffrent kinds for the 400.

This is for there three diffrent cams.
Copy'd from site:


#1= All around performance with added mid and upper end power. Stock springs OK. Designed to work with high compression piston and exhaust. Compression release removed. hardwelded rockers are highly recommended!

Accessories Required:
HR-H00 / $65.00 / Rocker Arm


#2= Performance profile increases overall power. designed for use with a racing piston and exhaust. Requires spring kit with shortened valve guides. Compression release removed. Hardwelded rockers highly recommended!

Accessories Required:
HR-H00 / $65.00 / Rocker Arm
VC-H04 / $95.00 / Valve Spring Kit With Titanium Retainers
VG-H04 / $20.00 / Valve Guide, Shortened


#3= Special profile designed for TT/flat track racing engines. Requires valve springs, shortened guides, high compression piston and exhaust system. Compression release removed. Hardwelded rockers highly recommended!

Accessories Required:
HR-H00 / $65.00 / Rocker Arm
VC-H04 / $95.00 / Valve Spring Kit With Titanium Retainers
VG-H04 / $20.00 / Valve Guide, Shortened



I would recommend going with a Hotcam though. You dont have to do anything special with a Hotcam...just break it in and go!!

Sparks makes a drop in cam for the 400EX. but without installing rockers or guides, Hotcams or Sparks is about it

Hot Cam stage 2 and call it good. Unless you don't mind upgrading other parts, i've heard pretty good thing about web cams.

XR 400 cam, I knew there was one.

Sure. It's a bit more aggressive than the stock cam. Although, IMO not enough to be worth it when there are other choices available. I consider it a nice option for someone that wants a bit more and insists on staying with OEM parts. The XR400 HRC cam would be better but good luck finding one of those.
