I got a new to me 96 rs last year from Rising Sun. The only problem I had seemed to be other than full throttle jetting which I've deduced is from me running the D series needles with leaded fuel(Sunonco puprle) rather then the B series. I any event, what else should I look into? How do I tell what head is on my bike(lead/unlead)? I'll be doing a lowend rebuild along with the usual maintenance items.
