Honda-SOHC

Hi everyone,
  I've recently bought a '78 CB550k, well to be honest what I actually bought was a v5, a rolling chassis and 6 boxes of parts which make up the rest of the bike. So I'm sure I'll be logging in regularly for your advice to get it back in one piece I intend to make it in to a road legal version of my avatar pic, an RC181. It will be an inspired copy not a full blown replica, unless I win the lottery  It won't be a quick job as I have quite a few things I still need to finish apart from the bikes I've got a '87 mini 1000 which needs some welding...obviously  and a vw t4 which needs the rear fitting out.
 Regards
 Stu
