Next to it is a '97 XR600, and on the far end is the original lower end from the bike.
I want to use the original cases to keep the numbers matching but I haven't decided what combination I want to stuff IN the cases.
Quite the hodgepodge of RFVC components there
Any problems running that XR5 head? Did you use the old style cam chain with the XRL bottom end? Valve cover from the XL6?
Did you do anything to seal up the oil chamber so it doesn't leak out around the cam bearing where the valve cover meets the XR5 head?
How well did the combo work?
