I picked up a 2003 XR650 about a month ago and I'm loving it. The only problem is that I do a lot of trail riding and the bike can't go slow enough through some of the more technical terrain. I find myself stalling the bike and/or popping the clutch far too often. I would like to gear my bike down a bit and wanted to know if anyone else has any recommendations or experience with this. Would it be sufficient to get a larger rear sprocket or am I going to have to get new gears?
