I have a 1978/9 320 Majesty, its been hanging araund for years with hardly any use. It was started up every two or three years and always started second kick or so and ticked over superbly. The problem was it would not rev and was very hard to ride as it 4 stroked when you tried to ride it, so it just sat there. I have recenty tried to sort it, I was reluctant to try and remove the flywheel as I had no puller and had been told that even with one its sometimes a pain. But get this, it started to come off while I was messing with it I heard a slight scraping and it was the flywheel touching the inside of the cover. I removed it and changed the points, I fitted the new points on the back plate in the same position, and as the old ones were ok really I thought it was about right.The comming loose of the flywheel had turned the key to dust so I made another one. The keyway was a little damaged so the key was loose, so loose that the magnet pulled it off each time I tried to fit it, so I stuck it in with locktite. Before I did this I put it back without a key and alough it was a pig to start it ran much th same as before. (Back to square one) Its now stuck in with the flywheel on and it will not run (timing)??? I have got a good spark and fuel to it but it will not run.
I don't know the correct points gap but have a feeling it is big (something about the timing as its now a 320) and the back plate is all the way forward in the slots as it was before, the only other point worthy of note is that I had to tweak the coils as the flywheel was catching them when i put the flywheel back. the only comclusion to this is that they must have been knocked by the flywheel when it came loose, I undid the four cross points and adjusted them so the flywheel did not catch If they have to have a specific clearence I am not aware of this. Sorry about the long thread but it may save a lot of questions.
Thanks in advance
