any chance you need a little more jetting on the side the power valve is blocked off(presumably rear side)dont know what the stock jet sizes are for 650, but usuallu when a power valve is blocked off you can go up maybe 6 - 8 jet sizes. just a thought art

Here is a link to a photo of the car at the track. From the looks of this I have good weight transfer. Would 90/10 shocks do much to help this car?
