I just bought my first brand new vehicle, and it's a DR650SE 2011! I'm pretty happy about my purchase right now, but was told from the dealer that the reason for the popping on decel was that california regulations required a lean jet setting to be sold in california. They assured me that it in no way affected performance, but of course, how could that be true. I just rode my friend's '09 DR650 and it has WAY more power, and everything is STOCK from Mississippi. I'm still breaking mine in, so would the break in itself inhibit the power that much (like less compression from "unbroken" rings)? Or will simply removing the california settings fix me right up? And WHAT ARE all the California changes?? Thanks so much for the help! I'm taking off across country this summer (right after it's all broken in and modified with skid plate, luggage rack, etc).
