Yes, light by key

Light by the key = high lift cam big valve head so should be as fast as a 6 volt 90 with out the battery problems ,the best C70 engine there is .

Standard is 15 x 39, bungee boy.

Ooooo. Forgot yours was a 6v C70. I may be wrong. Better check that.

Well I found out the ratios after a sprocket bolt worked loose and tried removing itself from the bike via the chainguard!
It's 14/39!
Straightened chainguard out and ordered new chain/sprockets, a 15 front this time, cush rubbers, brake shoes front and back, all wheel bearings, new sprocket bolt tabs, they were knackered which is why bolt worked loose and lots of other bits.
Still loving it though
