You should be able to find a low cost replica coil on ebay I would expect. There are lots of new coils out there that have become available over recent years.

I rebuild closer to one race motor per each 12 years or thereabouts, so Ed has the running on street motors. You have a high performance valve train and a 5 speed trans, I would try the cams and see how she runs. You must get your engine guy to check for valve to valve clearances as well as valve to...

Vince, that's much better. I did print out the original pictures and scaled them but these numbers are way better. That's a lot of lift. What do we know about the cams? Are there any small numbers stamped into the end of the cam shafts or more probably engraved into the ends or perhaps into the shaf...

A reasonably accurate measurement across those 4 points would be wonderful.

That split cam looks like it started as a CL unit and the tacho drive looks like it was machined off a CB to make it work. Alternatively it might have been supplied that way as a billet cam suitable for CL (no tacho) or Cb (with tacho). I have a full race cam here without tacho drive so that I could...

That is a really nice bike. Not a lot I can add. As someone mentioned, the pistons are CB350 machined to match the head. I never had much joy with copper head gaskets and use COMETIC on all our race bikes. Gearbox is an early NOVA. Mine had the same shafts and similar shift mechanism. I am not famil...
