Hey Ducman,
YEP!!!!! I actually ride mx...I think I may be a little crazy. I'm always searching for more top end out on the track..I don't drag at all, so most of my mods have been to the suspension and chassis..I don't plan on porting for a while, if at all..just looking for the pipes that will give me the highest rev before they fall off..According to the guys at dyno edge and 4wheel thunder, I can get 12,000 to 12,500 out of the thunders with stock porting and up to 14,500 with a drag port!! Whew!! Thats some crazy R's!!
