HOTCAMS Camshaft - Stage 1 Exhaust

Yes you can mix the cams. It would be recommended to run them as a match set from a performance standpoint. This will not cause you any issues on the 2005 RMZ450.

The camshaft style may change depending on your application, but for the Stage 1 Exhaust it will come complete regardless of the model.

re jetting is not always necessary but you may want to contact Hot Cams directly to see if they have any jetting recommendations. you can not fond the Stage 2 because they do not make it for that model.

if you are looking for more power, get both cams.

I wouldn't recommend running an aftermarket cam and oem cams at the same time. The curvature will be off and may cause the bike to not run properly.

I can only speak for my XP with an older XR650Ls, these are my ticket and have built a few now. This is a top flight product and it woke my bikes up drasticly. They did wake up the bottom end just a hint, but what a rocket as she builds! The stage one is great for the average to expert weekend warrior, but with the top end cam the phrase "twist as shout" realy comes to mind. When I used the stage three I did the works, porting, pipes, jetting, ignition, compression and boreing. Big money, and got a bike I sold that winter. TOO FAST !!! With my aplications, I had to remove the motor to do the job correctly, but once that was done and the motor secured to my bench, it was quite simple. You do need to review how to unload the cam chain tensioner/s, but that is the only hick-up for install. YES it WILL mess with the way the bike runs and the jeting requirements. More power, more fuel! I sugjest you find a forum (Thumper Racing works for me time and time again.) and ask questions and they should be able to give you base line start jeting. From there is up to you and how you ride. READ THE PLUG !!!! Tan is good, black is too much fuel, nearly white, to little. Good luck!! Old Thumper Dude

depending on the bike a stage 1 will increase the bottom to mid or just the mid for better throttle snap. Usually the stage 3 is reserved for big bore kits.

Excellent midrange & top-end power increase.

Cam's control the opening of the valves. some 4strokes come with dual cams or single cams. Yamaha for instance has 2 cams, one for the exhaust and one for the intake. By changing the cams out detunes or tunes the bike performace to better cater to a specific need a rider might be looking for. After market cams differ in lobe durations compared to the stock OEM. Cam technology can take years to understand, so read up on this subject if you want to know more.

great mid to high end range increases.
