Mike, what's wrong with your seat tube and oil pan? Are these the ones you posted about a while back? (dented pan and wallowed seat pivot holes) Have you looked into repairing these two items? You can beat the dents out of the oil pan with a block and then using the ball end of a ball peen hammer. No ones gonna know or be able to tell after you smear a little Bondo over the irregularities. You could drill and install oversize pins in the seat or build them up with weld and weld up the crack at the bottom. I'd get the used lights if I were you and just knock the dent out as much as possible if it is big, if not then just Bondo over it. Dents mean stretching and sometimes you can do worse if you try to pop some dents out so look at that dent carefully. The throttle arm might be better bought new. It depends on how much the part has been stretched. It's just like bending a piece of wire back and forth till it breaks; each time it gets a little weaker. My guess is that it is to this point already and that's why it was welded. Chunk that booger and get a fresh one, it will be allot safer I would figure in the event it broke during operation. OEM might have the suport but I would just blast it and coat it with POR-15 then smooth over with filler. This part could be subject to acid leakage again and filler as well as the rustproof will not be eaten away like the original steel part.
