Guys just thought I would let you know about a quick little fix. I have an R&D ride plate and when it was installed the speedo stopped reading correctly. I noticed looking at it that the transition between it and the speedo that there was a little difference in elevation. All I did was take the dremel tool and grind down the difference it the ride plate and made it have a smoother transition. It now reads within about 5 miles an hour by the GPS verses reading in the teens at WOT as before.
