- Still kept the dimpled plates. - Inner clutch hub drilled 3mm hole about 10mm centres with existing, on the side which had more space. - The outer clutch basket was drilled center of each finger, which is minor compared to the after-market MX baskets with large slots milled in each finger. I should have tried each method individually to identify the fault but didn’t have the time, spent to long with a spanner in my hand rather than riding. If you have the time try above but without the EBC cork plates & Rock Oil, it may work & save you a bit of brass.

I had the same problem, a right head banger, I fully stripped the whole clutch system, filed edges, cleaned every part, replaced all clutch seals, installed new Apico dimpled plates & fibres (chamfered all sharp edges) & filled with fresh dot 4 & ELF HTX oil, resulting in absolutely zero change to the clutch dragging issue! Just before scrapping the bike I ended up giving it another go, installed new cork EBC clutch plates, changing the oil to Rock Oil gear pro 75W, drilling a 4mm hole in each of the outer alloy clutch basket fingers & an additional 3mm hole in the inner alloy clutch hub (next to & in-line with the existing hole) the result was best feeling clutch ever, still easy to find neutral after 2 hours of riding, no drag whatsoever, also no slip on the big sections - I run only 4 standard clutch springs rather than 6 for a more progressive feel & it’s a full 300cc!
