Hotcams product never fail one of the best.
Bought for an upgrade of my XR400R dirt bike.
This hot cam is perfect for mid to top end power, easy installation for a QUALIFIED mechanic. Will increase power that is noticed immediately.
great BANG FOR THE BUCK!!
*****WARNING IF INSTALLED INCORRECTLY CATISTROPHIC ENGINE DAMAGE WILL OCCUR***********
The Hotcams stage 2 was a great power increase, specially in the upper RPM range. Possible you will have to do a little machine work on your head for the intake lobes to clear, other than that its a snap to install
I only have a couple rides with the cam but fealt like I could notice a difference with the response and power of the bike as soon as I turn the throttle. Im happy so far. I installed this on my 2008 CRF250R with athena big bore kit.
I installed this on my '05 crf 250. i honestly expect more of a power increase. Its not as good as i had thought but it makes a difference. And the best part is.... IT CAME WITH FREE STICKERS!!
The power gain with this product was just what i was looking for. I installed it into an 09 crf450r and immediately felt the difference. After about half throttle, the bike really begins to pull and the power never seems to drop. It didnt come with any instructions for taking the decompression flange off the stock cam and installing it on the new one but its not too hard to figure out. I highly recommend this product to everyone.
easy installation and big power gain. although the order took longer than 3 days it was worth it
Note: Uses stock auto-decompression mechanism. Uses stock valve springs and rockers.
