So, I'm finally working on my RGS Spitfire, and I've got a ton (or so it seems) of extra parts. I'm thinking I can sell some of the excess to finance the build. What I'm wondering is what you more experienced A10 jockeys recommend I hang onto as spares. I've got probably a half dozen magnetos, a couple non-RGS swingarms, a couple steering stems/clamps, STD and SC transmissions, at least 1/2 dozen cylinder blocks/heads, 4 extra crankshafts, multiple connecting rod sets, haven't counted heads, cams. I have the engine (no numbers) that was in the bike when the previous owner rescued it from a salvage yard (20+ years ago) as well as another apparently complete (also not numbered) engine. I plan to keep both engines, at least until one is up and running well, and one each SC and STD transmission. What else should I keep for possible future use?
