My new to me XR650 had it's countershaft seal fail, all the oil drained out on one ride. The guy riding the bike didn't notice anything until he stopped at the truck. Anywho, pulled the valve cover off, the cam and followers look like hell, deeply scored. No signs of excessive heat though. This looks like it's going to be an expensive fix. Anybody out there been through this before? Looks like the valve train components are going to be in the $350-$400 range at service honda. The crank is going to be $350+. This was a very low hour 2000 XR650, it was going to be my dual sport. I'm wondering if I should just be parting her out at this point as it looks like parts could easily be over $1000. Any advice appreciated. Thanks.
