(Quote from Crazy Horse) "These tribute bikes are screaming for twin cylinders."
Don't know if my bikes are tribute bikes (maybe tribute to a different era),
but can I be included as well...? I'll scream for a twin cylinder if ya want me to... =-]'
Shouldn't take that long for completion I wouldn't think, as the motors are still "siamese" in that they have their own dedicated crankshafts. Just a new cast case to join them out of your mock up mold.
The synchronization can be changed at anytime, as it is as easy as spinning one cylinder into position
before screwing on the small gear on that side to the clutch gear. (may need to modify the keyway for multiple positions on that side.) Other than that, it pretty much seems all cut and dry....
Unless I'm missing something of course. Maybe better carburetors that would allow more acute synchronization adjustments.
Something very amazing is happening in the Motorized Bicycle World that I am sensing very strongly.
A shift into more mainstream interest abroad. More players are coming onto the field with their skills and knowledge. Eminently, Motorized Bicycles are going to evolve at a more rapid pace as of late. I feel this evolution is strikingly similar to The Birth Of The Motorcycle. The Harleys, Excelsiors, Indians, Hendersons, and the like, all had each other back in the day, which led to their own company's evolution.
They had friendly competition in the name of Board Track Racing.
and it benefitted all who adore the motorcycle as it is today.
