[QUOTE="jmics19067, post: 871087, member: 27963"] what I am working with; 2004 WR 450,yz cam,throttle stop,GYT silencer with GYT 96 decibel end cap. what I notice& what I want; As the usual feel /mindset the WR cam just doesn't pull very well, the YZ cam pulls very nice but a little beyond what I need ,also believe the 96 decibel endcap is holding it back a bit at the upper revs. The bike is a do it all play bike for my novice(?) skills. have been riding for about 20 years not fast by any standard but ready to try and ride anything,MX,Hare scrambles,Enduros,Dual Sports,trail riding , and the most important ,racing to the beer meister when the day is done. I was wondering if it is feasible take a yz cam apart and repress the gear on say 5 degrees advanced? Trying to get camshaft timing and exhaust configuration more in tune with each other and hoping that the 5 degrees won't mess with auto decompresion at cranking /kicking speeds. Before I try has anyone ever tried this succesfully? Are Hotcams available for a low/midrange boost compared to the yz?Also would advancing the intake cam a couple of degrees be beneficial to my ideal by lessening valve overlap? thanks [/QUOTE]
