[QUOTE="Rider 007, post: 571818, member: 17322"] Dan, please post the results of your testing as I'm curious to what effect it has. I have an 03 model that I plan to test sometime but I'm spending what little riding time I have tuning my CRF. Have you thought about disabling the RC valve so it doesn't open? I've never personally done this but heard it can be effective in smoothing out the power since the valve stays closed, therefore the exhaust port stays small. Regards [/QUOTE]
