Hello All,
So I finally have received my '53 Golden Flash back in Australia from my Isle of Man trip in August. Bit Mildewy from 6 or so weeks locked in a container. The guy who freighted the bike(s) was very pleased with me as the dripping oil has given the container some extra rust protection for a while. Hmmm !.
Riding the bike towards Felixstowe in the UK, the lights went out shortly before arrival with accompanying extra noises sounding like loose chain. Couldn't do much there, but back home and took the timing cover off to find that the Dynamo chain was very loose, to the point that it had been rubbing on various parts of the casting on the timing case. The drive sprocket had sheared the rivets that attach it to the drive hub and I suspect that the Dynamo had been mounted with a loose adjustment or had come loose whilst I was riding over there.
When I removed the smaller sprocket at the Dynamo, I noticed that it wasn't snugged up on the taper, rather it bottomed out on the bearing boss and had a lot of wobble in the taper. It could be the wrong sprocket perhaps, incorrect assembly on the Dynamo perhaps, or the nut has been loose at times (it was tight this time) and worn the taper down on either the Dynamo or the Sprocket. First thought was to turn a little off the rear of the sprocket but this would misalign the chain somewhat.
Anyone had similar ???
