The drive set-up is simple, and very easy to maintain.
Note the fact that the bearing shaft is eccentric to the housing...by turning the entire housing in the bracket...the engine chain can easily be tensioned.

Guys, The Bike came out sound perfection. This is how a machinist builds a bike.
This is thee most advanced and reliable motorized bicycle ever built.
Congratulations on your excellence!
Thoughs about the Eccentric Jackshaft:
Looks like the shaft itself goes all the way through to the other side, and could be lengthened to facilitate a gear on that opposite side. I see it also incorporates the mounting flanges for the Morini.
Seems like it could be designed as a stand-alone unit with no engine mounts and become
The Ultimate Jackshaft
for custom builders like me. In that, the engine of choice I use would have its' own mounting system.
Is the jackshaft 5/8", with 1-3/8" bearings?
I love the jackshaft, Jim.
I would love to see a universal unit that would give so much freedom to custom builders, because a sound jackshaft to work with unique applications is hard to create on our own. I spend so much time building my jackshaft set-up by hand, it's hardly cost effective.
Once again, excellent work guys!
