Hot cams

[rich1121]

I have a stock 400EX with a curtis spark pipe, jet kit, and K&N filter. I am considering purchasing a Hot Cam stage 1 or stage 2 cam. Has anyone used one of these and if so was it worth the cost and effort to install?

Get the Stage 1, Stage 2 is for bigger bore ex's. I have the stage 2 in mine, helps my motor make 42hp

the stock cams in the 400's, and 450rs are really restrictive, i put a stage one in my 450r and it really woke up, you will really feel a difference

i run a HC stage 1 in my 426ex and love the bottom end to mid gains.

It should be the complete opposite, look at their site.
Stage 1- More mid-top end
Stage 2- Same as stage 1 with more top end

so it shouldnt be bottom-mid gains

it is the combo he is running that makes it work

Aye he's running it on more CC's. From my VERY LIMITED knowledge... Generally that will shift the power curve down in the RPM range a bit since the cam is tuned for max power at a certian volume throughput. A larger displacement will get to that volume throughput at a lower rpm. Of course modifying the intake & exhaust ports will also shift that point.
