Stage 2 Intake: Dual-cam motor.
Added top end over Stage 1.
An incredible way to boost the midrange and top-end horsepower.
Increases over-rev on motorcycles and ATVs.
Easy to install with minimal valve adjustment and re-jetting requirements.
The camshaft uses such precise engineering and build quality that they are consistently voted top product of the year.
08 kfx 450r can I put in stage 2 intake and exhaust hot cams and go or do I need to worry about adjusting other things and with a big gun tuner do I need to worry about what that does to my timing

Hot cams list these notes on the stage2 for the KFX450:
Stage 2 ITR: Dual cam engine. Intake and exhaust cams sold separately. Good midrange and top-end increase. Cam uses stock auto-decompression mechanism. Uses stock valve springs.
For sure get a factory service manual to help you time the cams properly and set the correct valve clearances.
You may need a EFI tuner when you are done installing them. We would suggest to ride the bike after installation and see how it runs before making your purchase.

Modify the air box?
2014 Kawasaki KLR 650
Exhaust/Intake cam notes that you "must modify airbox".... what, exactly, does this entail? Is it cutting, trimming, or drilling something? Is it buying additional parts? I intend on using this part with full exhaust, jet kit, and higher flowing air cleaner.
Please advise. Thank you.

For the KLR650 you must drill holes in the top of the airbox to allow more airflow. You want to fit as many as possible.
How big of a difference in power over the Stage 1 and Stage 2 Hot Cams?

With the Stage 1 Cam you should should feel significant increases in mid-range and in the top end. With the stage 2 for your bike you should notice gains throughout the entire power band with significant gains in the mid to top end range over your OEM cam.
I have a 2010 yz450f and I want to add some more power to my bike and I was going to get the intake and exhaust stage 2 hot cams. How would I make it so it gets enough fuel if my bike is fuel injected?

For the 2010 YZ450F, Yamaha offers a a fuel injection programmer that allows you to modify the fuel and ignition curves to tune the engine for modifications through their GYTR parts program. There are also many other options available from aftermarket companies also to tune the fuel injected models when modifying the engine.
