The cam was hitting my head just a little bit so i had to buff down a section of my head to make work. Wasn’t too big of a hassle but still something to keep in mind. Installed in a 2014 yz 250f. Other then that it was good

Great modification to do to your bike. I built my Kx450f with these cams and I could not have been happier with them!
Stage 2: boost the midrange and top-end horsepower.
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.
