I have to say this is looking more and more interesting. I have to wonder if the bike is brought here what changes, if any, they will make. A Twin would be rather tasty, or i could settle for a boost to 500 cc with F.I. This bike is making me nostalgic for my old Yamaha RT1 360.

You probably caught Sid Lal's comments in the video about EFI and ABS being already to go for where required.
What I want to know is how thick is the cylinder barrel wall and how thick is the cylinder liner ?
If there is enough thickness in the liner to overbore 3mm the result would be 428cc and with 10.5:1 compression that would be notable with the Mk1 butts dyno.
If there is enough material in the cylinder barrel to bore and sleeve to 86mm then it would be square 500cc lump if my math is any good.
I wonder what sort of surgery it would take to graft in a kicker ?
