Great upgrade!

Major difference when the intake and exhaust are added as a set. The low end torq benefits the most from the installation.

Just as advertised

I bought a set of these cams (intake and exhaust) for my '07 YZ250F. They boosted the low and mid just a bit. I noticed just a minute amount of over-rev loss. But, the loss was barely noticable. These cams work good. Although, I have heard the stage 2 work the best for the Yamaha.

If I have a 2006 Polaris predator 500 and install both intake and exhaust cams how much more horse power will I gain?
Will I need to re jet the carb again after already rejetting it for a complete system hmf exhaust jet at 155 now. Will I need to bring it up to 160 if I add the cams?

Do I have to re shim the valves on my 2012 RMZ250 when fitting stage 1 hot cams or can I just drop cams in and go?

You need to at least check the valve clearance as in most instances the valves do need to be re-shimmed when installing new cams.

Does the thw hotcams stage 1 exhaust cam come with the auto decompression switch?
MotoSport Staff
Over 9 months ago Location: Portland, OR, USA
For your 2006 RMZ450, the Hotcams cams use the stock auto-decompression mechanism. Uses stock valve springs also.

I just need an exhuast cam for my 05 rmz 450. Can I run a stage 1 exhuast Hot cam and the OEM intake cam together?
MotoSport Staff
Over 11 months ago Location: Portland, OR, USA
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.

Cams Included?
It appears the cams are removable in the picture. Do these (both intake and exhaust) come with the cams or is it just the camshaft?
MotoSport Staff

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

Jetting?
im understanding that when you change these cams its better to change the jetting in the carb also. I have a 06 kfx 400 and how do i know what to change the jets to? and i cannot find the stage 2 cams for my quad. why not?

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.

Not sure?
should i buy both an exhaust and an intake cam or would one be just fine and give me extra power? which one is better?
MotoSport Staff
Over 3 years ago Location: Tualatin
if you are looking for more power, get both cams.

Can i use my stock intake cam with the exaust cam from hotcams stage 1?
Expert MotoSport Staff
Over 4 years ago Location: USA
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.

Difficulty to install?
these cams seem to be basic drop ins, woiuld it be unreasonable to install these in my gargage with some common sense and general mechanic knowledge? about how long would you think it would take (would probably do kibblewhite valves and springs as well). and finally would it severely effect my jetting or my hrottle response down love

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

Whats the difference between stage one and stage three?
MotoSport Staff Expert
Over 4 years ago Location: Portland, OR
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.
