I cant wait until its done so i can ride it. I just happen to have a cpl rolling frames over here
Nice builds 650 sounds like you know what your doing w/ these motors
Side covers and elec start stuff from an XR650L onto an XR650R? That can't be right. They are completely different engines that share no parts. Now, side covers from an XR650L onto an XR600R--that I could see as those are nearly the same engine.
