I've completely striped down the gearbox, in frame, and preparing to start reassembly. Original plan was to leave main bearing/sleeve gear untouched and just do all other bushings, layshaft bearing etc. But realized that getting good heat on shell in area of layshaft would be difficult without full access from drive side end...so took primary off. All bearings came out with lots of heat. My sleeve gear has no circlips for the inner bushes. One bush, timing side, came out with finger pull, other one needed a proper puller. Should these be both press fit? Is Locktite green the solution if so? Generally, all innards look top notch . No gear teeth erosion evident. No obvious scoring etc. Only worn bits were the kicker pawl and clutch release roller (which had a flat worn across about 1/3 of the diameter!). Bike has 12000 miles. Even the Dreaded Portugal bearing nice and smooth, cage pristine. Got the phenolic ball bearing from Mick Hemmings.
