Just a quick one, I had issues with this Comet and it's clutch slipping.......standard 4 spring type, all components in very good condition with good friction plates that have a woven metal impregnated inserts. Springs seemed Ok at correct specs and length and so on, but on every test ride it would slip. I even had the spring adjusters done up to the point of coil binding and still would slip......... This was running with the recommended Motul 10 w 30 transoil that we have discussed on the postwar single clutches.........anyway I stripped the primary again, thoroughly cleaned the plates in thinners and blow dry with compressed air.......... I did rough up the steel plates this time for some added bite..........reassembled the whole lot, but this time only used good old ATF ..........Hey bingo........No clutch no slip no more........Happy as the cat. Whilst I had the lot apart again, I made up a cork disc with a hole in the center to clear the gearbox mainshaft, this cork disc just kisses the large ID washer that forms the inner side washer for the chain wheel bearing assembly. Not so thick so it creates drag on the mainshaft, just enough to touch with a light coat of grease.........Now the primary inner seems to be holding oil in as well.......Two birds with one stone.......... You can be lucky sometimes.
