Had a potential disaster in that I'd obviously not got the circlip on the end of the kick starter shaft in properly and as I was doing the above turnover all the springs and gears came off the shaft into the sump. Luckily just managed to reassemble it with the bike on the side via the sump.
I had exactly the same thing happen to my CB550 yesterday. Had just fitted the kick start lever and Graham pushed down on it (it's on the workbench still on an engine stand) the kick start went down (yes, Graham can get the kick start down by hand on a newly rebuilt 550
)and, clatter, clatter, we heard a load of bits fall into the sump. Turned engine over onto her back, took sump pan off and the little circlip on the end had fallen off along with some other bits on the shaft. Easily rectified by putting all the bits back on and securing the circlip with some retaining gluey stuff just to make sure it doesn't come off again. If the engine had been in the frame and full of oil, I doubt we would have heard the clattering on the first kick !!!
