Well a little bit of an update. I found a A15, apparently has a cam in it but im not 100% certain. Its never been started since a full rebuild 2yrs ago. It still turns over free as a bird and the bores are rust free and still have the cross hatching on them from the hone tool. So i think its a good one! I may get the head ported and polished(along with the manifold) at a later date.

On the carbies front, I have found a mate of a mate who is going to make me a alloy manifold for cheap! So im starting to look for carbies now. Smaller choke(then what i originally stated) seems to be the go. So ill be looking for 30mm ish. Probably off about a 1200cc bike. Ill see what i can find.

Still donno what to do about vac advance. possibly take it off and play with the centrafugal advance weights? Ill be using my E15 elecy dizzy with the weights right at the very top(uses Mitsu 4G15 cap and rotor so maybe internals are the 4G15 too?).
