It just doesn't make sense to throw away a good engine like the 650R. Why not lighten up a few parts on the R and send it out as a model upgrade next year? If the other companies are moving into big bore dirt bikes, this doesn't seem like the right time to drop the 650R. Sounds like the right time to make some improvements on what you've already accomplished. I agree, shave off a couple of pounds and install the magic button and you would have the perfect desert bike!!
