My “won’t free up” clutch issue seems to be an incorrect spring plate....Dimension “A” is about 8.5 mm, whereas the correct plate dimension “A” for the clutch parts that came with the bike would seem to be much shorter ie about 2 mm. What would my plate be from and I would prefer not to get this machined down as an original part off “ something Duggie” and do a swop instead...?
