After a few rides with the new improvements the chain tension held much better than the original configuration but still I head to close the tensioning screws ones in a while.
A second series of improvements is needed,
So this time I replaced the three M5 100mm screws with six M5 12.9 grade short screws, that way the fastening force is much greater hoping this will solve the problem for good.
The blue plastic is a stiff plastic with aluminum hose that I sliced in the middle and placed on the motor case to prevent from the tensioning screw from notching the motor case.
I took this opportunity and prepared a final version of the aluminum spacers and replaced the preliminary spacers, this should increase the contact area of the lower sheets.
