Okay, I did it: I converted my ´82 CM250C from chain to belt drive (not an easy project that is ;-). The bike runs great, however, I don´t have any information about the correct belt tension (I don´t have the OEM measuring tool, seems not available any more). So I would need to know how much slack the drive belt should have and eventually how much pressure should be applied when measuring the slack. For the moment, the slack is set to 1.9 cm (6/8 inch) at \
