Hello all, just got my 54' B31 fired up for a test ride today. It has not been running for almost a year now. This last winter I changed all the oils. I made a novice mistake of not checking the clutch to see if it was free and separated before I installed the primary cover. Well, you guessed it. Before I started it I checked to see if would break free by pulling clutch in and rolling it back and forth, nope. I even went as far as to push it running, click into low gear and ride it for a mile or so with the clutch pulled in, different r.p.m.'s to no avail. My question is does anyone have a secret trick before I remove the primary cover? Thanks in advance!!! Kevin

A higher gear and going guns blazing up a hill with the clutch out is your best bet. It where the clutch is most likely to slip, having the clutch pulled in is not doing anything to break the bond. Another option is to get up to say 30 mph and then change to a lower gear, let the engine rev drop to idle and then drop the clutch lever so you are using engine braking on the clutch.

Bingo! …… First, thanks commando for chiming in! I was telling a good buddy of mine who is a Jap bike nut. He told me some of his do it frequently. He gets things going like I did, then lays heavy on the throttle, then hits the rear brake hard with clutch engaged, and he says that sometimes it may take a few hard hits to get it loose. I was a little reluctant to try this with the ole B31, fearing I might end up pushing it back to the shop. It took 3 tries, but now, after a 10 mile jaunt, we are both very happy.
