Default Re: what did you do to your motorized bicycle today?

Yea I would like to put a rear suspension pivot right on the rear jackshaft but there isn't enough room on the shaft anyway. I could put it just behind the JS and the chain slack due to misalignment would be minimal... But man it's a project for another bike I think. The engine is a briggs & stratton 3.5hp- 148cc and the block you see is a worn out aluminum bore block. Have a thread in hubs/gearboxes on this transmission. Here is my first solid mockup with JS solid. The slack between shafts will be adjusted by moving bearings, the overall slack bias can be moved forward or back to tension or loosen the engine chain while doing the opposite to the final chain, and the entire assembly can be moved up and down the seat tube which will adjust slack for my pedal chain which connects to the rear jackshaft.

Is it normal to be working on your bike till 3am?
