Due to the variations that may come into effect when tuning an engine (i.e.
pipes, intake, altitude, cams, displacement, standard or high compression pistons, etc.) we CANNOT offer jetting recommendations.
either buy K&N's filtered lid, or make your own with a small flat filter (newer cavalier/cobalt filter).
After two years of sitting on my filter and not having my full power potential I rejetted my carb to run an open air box and this aboslutely screams from mid-top.
However you can expect to see a noticeable increase in low-end torque gains across the entire RPM range.
This hot cam is perfect for mid to top end power, easy installation for a QUALIFIED mechanic. 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. I installed this on my 2008 CRF250R with athena big bore kit.
The power gain with this product was just what i was looking for.
As well as Excellent top-end power gains with great over-rev. If you do it is minimal, but important the lobes clear the exhaust rocker and the cylinder head. If you are unable to a local machine shop can do it at a reasonable price.
