Hi Tomy4x
Martin was spot on, I changed the lot, Apico steel plates and friction plates, the difference is incredible, zero drag, easy selection of gears and neutral, can even kick start it in gear! Purchased mine from eBay they are advertised as replacement parts for the Honda CR 250. The plates came with new springs, I fitted them but the clutch lever became very stiff, so I replaced them with the originals and everything worked perfectly.
