just wondering if anyone is running hotcams in their 450's. i have a '06 yz and am looking to get more power out of it. i previously had a '04 and did exhaust and noticed only a minimal gain it was'nt really worth the money so im wondering if hot cams are going to make more power for the money ive read tons about them but just want some real input from actual users. im kind of a big guy 280lbs and love the 450 just looking for a little more umph out of it with out going broke. the cams sound like a pretty good performance upgrade. any input is greatly appreciated thanks.
