Just a note about stage1 or 2 etc
The differences between the two diff cams offered will not be the same between diff models or makes etc, and what goes for the 400ex may not be the same for the raptor or whatever else.
I know a lot of you knew this but wanted to put it out there for those that dont.

Hi Brad,
The stage 2 cam in a stock bore, stock compression 400 will loose a little on the bottom end, but has very good gains in the mid and top. When people have the 440 kit with higher compression, it takes the usable power, and torque and moves it lower in the RPM range. So a the stage 2 in a stock motor will loose bottom, and a stage 2 in a 440 with higher compression will have very good bottom end. The 440 motor needs a lot more cam to breathe than a 400. If a person put a stage 1 in a 440, it will have very big gains in the low end, ok gains in the mid, and go sort of flat on the top end. As far as the rockers, you should never use hardened rockers with our cams. The cam companies that recommend, or require hardened rockers, are stock cams that have been hard welded, and ground to their specs. That makes their cams harder than the stock rockers, and the cam ends up chewing up the rockers. In our case we manufacture our own cams to our specs, that have the same hardness then the stock cam. Using hardened rockers has absolutely nothing to do with the larger lift and duration of a cam, it has to do with the hardness of the cam. If a person were to put hardened rockers on one of our cams, the rockers would chew up the cam (the reverse effect). The only reason to worry about rockers would be if your stock ones were worn out, then they would need to be replaced with OEM rockers.
As far as adjusting the rockers, once you have it apart it will all become pretty clear to you. Go to www.hotcamsinc.com and click on instructions, that will help with installation, and rocker adjustment. The Valve lash settings are on a cam card that is included in the box that the cam came in, or on the website http://www.hotcamsinc.com/catalog.asp#TRX400S2-A then click on spec card. If you have any other questions let me know.
Thanks,

I was thinking about getting the Hot Cam 1 for my set up. (See below what I have) Does anybody know the difference between the White Brothers stage 1 and the Hot Cam stage 1.
THis subject probably has been put up before, but I did not catch it.

Either way if you want to get the full benefits of the carb and exhaust etc you will want to go with the hc stage2 or wb track cams but remember to check into if the wb requires the hardened rockers or not.
If you want to compare numbers I listed some info earlier in this thread.

So--440ex026 you think that the stage 2 will work for my set up. My motor is not consider a big bore over is it?? I do not know my compression, when I had the motor done by HONDA in Anchorage they never gave me the info on it.
So with .020 bored over, 39FCR Carb (not sure on the jetting) and Curtis sparks X-6 and the Rev limiter I will be ok and not "starve" the bike, as almost stock???[img]i/expressions/face-icon-small-confused.gif[/img]
Thanks for helping out on this situation, I am lost when it comes to the Cam, I never really got this far into motors.

The difference between the two is more than std v big bore.
If you look at the specs above and make the correction for the lift on the stage1 it isnt much different than the XR cam from honda. The advantage to the stage2 is in the duration and looking at your set up I think the mid to top end is your set up for MX type riding and your mods.
Plus you will need more air and fuel at rpm to allow the FCR to show its performace advantage and the shorter duration of the stage1 would be potentially starving the engine.
It would be a lot easier if someone who can explain this better posted but till then I will try to make it as easy to understand as i can
