Bought this and hmf full exhaust at the same time. Install and break in took some time but well worth it. I didn't see any loss in low end power and mid to top was a huge increase. Top end is great now.
Gained power from bottom to top! Makes my trx much more fun to ride
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!!

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.
