Having an issue whit my old lady,whit a slipping clutch,and i have replaced the clutchplates,put in cb900-springs,using a special oil for slipping clutches,sandblasted the steelplates - all adjustments r according to the manual - and only thing i hav'nt check is the thickness of the steelplates-and it's the only thing left that can be faulty.. So does any1 have any pro tip on where to get just the steelplates,in a complete package ,whit the outer double-disk aswell? it's a 1981 cb750 F btw
