Hey guys, Just got back from an AMAZING trip in Baja last week on my 650L. I LOVE my bike, BUT, do yourselves a favor and maintain the hell out of your countershaft and drive sprocket, specifically the splines. I'm sure there are other threads on TT about the subject, but it seems to be word-of-mouth-type knowledge that you should replace the front sprocket every time you replace your chain and keep the splines greased up good. Mine stripped all to hell the furthest point south we were going (out side of Mulege) and I might still be down there had it not been for some extremely helpful locals. Unless you get a kick out of tearing your engine in half, HEED MY WARNING!
