Hi Richard,
My 1927 Flyer had the exact same specs as the bike you describe. So a wide box and:
– flywheel: 20 T
– clutch: 44 T
– outrigger: 19 T
– rear: 40 T
I always thought it revved quite high doing about 55…. Much higher than my mates 28 Flyer with the same gearing besides a 22 outrigger…
So, I guess, it was pretty standard…just like in the BOS.
After my enginework is complete I’m gonna try:
– flywheel: 22 T
– clutch: 44 T
– outrigger: 21 T
– rear: 40 T
That should be a lot nicer to ride!
Erik
