Was already to make first long ride of this year today, but when I went to put it in first gear, clutch held in, clunck! Engine stalled. Tried again, and same stall. On CS, clutch in, I found rear wheel very hard to turn, almost needing two hands. Alway seemed OK the previous two around town rides last week. Checked clutch adjuster nut, slackened it off, then turned in adjuster until pressure on clutch spring felt, then back out 1/2-1 turn. This made no difference in hard to turn rear wheel while holding clutch in. Could this be a loose clutch basket nut (the one under the plates)? I followed OldBrits rec to only torque to 40 ftlbs not the 70 the shop manual reccomends...used some Locktite on it as well. Primary fluid is fresh, ATF F.
