I loved my 48 350 AJS only trouble I had was an inlet valve dropped on the M1 going to the IOM TT..Got it fixed in Northampton by a motorcycle dealer I found in a phone directory in a phone box (remember them) my mate took me in after removing the head beside tha motorway fixed and carried on no probs(I had cut the oil supply too mutch to the inlet)
I converted it to swinging arm later great bike..
