I am part way through that project, nothing horrible. you will have to cut the front mount cups off of either the tank or frame probably easiest to cut them off the frame then mount the rubbers through the frame, I have seen it done with a through nut and bolt. There is a current thread on here showing it. The rear mount will work as is.Beautiful bike!
I'm rebuilding my 78' Standard XS 650 into a cafe racer.
But I would love to put the XS 750 tank on this bike, looks much cooler.
Does anyone know if the 750 tank will fit the 650 without to many problems?
Cheers
Chris
