The Power Now Valve is NO JOKE!! It does just what they say it does which is idol to 1/2 throttle. It will NOT give you more wide open throttle horse power but will make throttle response much crisper. On a buddies 05 Honda 250X it made the low end come on much harder to the point the bike can be riddin a gear high in most conditions.
I just installed one on my 06 Grizz yesterday and it even idols smoother and would run without the choke much sooner. It will pull the front tires about 6 inches in high range from a dead stop, it wouln't before.
I havent been out of the alley with the Grizz yet, but the difference on the 250X was enough to sell me. More than just slightly noticeable.
Dirt Rider magazine named it thier product of the year in 03.
I got it from CYCLEBUY.COM.
Ok, I put on about 30 miles on Sat. I would say the Power now did smooth out the bottomend when negotiating tight and tricky obsticals. With a dirtbike it's more noticable with the manual transmission. The CRF250 has a stronger hit off idol and can be ridden a gear higher in a lot of tight and technical sections. With the belt drive Grizz it's tougher to compare.
