Fixed the Sprint sticking clutch issue, which I reported recently. Put the bike on the center stand with rear wheel off the ground, started and warmed her up, popped her into gear so wheel was spinning, pulled in the clutch (still sticking) and then slowly applied the rear brake. I believe there was a slight click or clank - not sure - and suddenly the clutch was free. Probably plates sticking. I've now got the clutch cover gasket (my dealer had one in stock - I nearly fainted!) so, if it happens again, I'll pull the cover and investigate.
