Hey guys I have a buddy that found a pipe and silencer combo that dodn't work 02. He went with a Pro Circuit pipe and the factory sound silencer. It did nothing to improve the low end. He has a shorty silencer in the mail so we will see if that helps. At the high elevations we ride at here in CO we need to figure something out to help with the low end. I have my jetting dialed in on my 02 and went with the V force reeds. I had a Rad Valve on my 01 and it made a world or difference but everybody said to go with the V Force. Any advice on how to make this thing have the broad powerband or my 01 would be greatly appreciated. Does the Boyeseen power valve covers help the low end at all. The claim they help, but I would like to know before I spent the $50. I am thinking of going with a 50 or 51 tooth for the rear sprocket. Also does the Pro Seal solve all the leaking problems. Twin Air offers the power flow kit that is supposed to fix the problems but I would rather use the Pro Seal then spend $99 on the Twin Air setup. Thanks
