Hi Edge,
Sorry I haven't responded sooner, just been covered up with work.
Happy to see you got it working. The design of your drive sytem is causing the "not as smooth as I would like it" issue.
Hopefully it won't get worse, and may smooth out somewhat with riding time.
Although you chose a drive system that hasn't done well in the past, you need not to worry, as there are several replacement drive systems available to keep your motorbike working.
Have fun,
