Hello, I guess Im stepping it up a notch, just sold my DRZ-S and replaced it with an'02 XR650R. Looking for a few tips/opinions, the bike is already un-corked with the stock carb re-jetted and has a Pro Circuit Type 496 pipe on it, but still has the stock head/mid pipes. First, any opinions of the 496? Second, will new mid/head pipes make a big difference? It also came with the stock can and both stock and opened exhaust tips. Im assuming the Pro Circuit pipe is going to perform a little better. Next, I want a bigger tank, I had a Natural Clarke tank on my DRZ and it was great, but seems like there are alot of people on TT that arent impressed with the fit and finish of the Clarke tanks. Maybe I got lucky, maybe the DRZ tanks are nicer for some reason. Anyway, whats the general opinion on tanks for the BRP? Also, I see alot of people who cut air holes in the side plastic, is this just on bikes with major mods (head work, valves, Cam) or will I benefit from it with a basic un-corking and maybe re-jetting again?
