Amelia Squariel: W/NG – Horn Restore

[ad_1]

 Properly it has been per week of cracking by means of little bike jobs, alongside welding up rust holes within the gasoline tank of one more Jap Bloc two-stroke, this time an MZ TS125 – however extra of that later.

For some whereas the W/NG horn has been slightly sensitive, as a result of the horn adjuster would not work very effectively resulting from a stripped brass lock nut, although I improved it quite a bit in the midst of final summer season by squashing the nut barely. It has an odd thread, 0.209″ x 36 tpi which I discovered by luck on eBay – it is a bicycle tyre valve core thread!

The adjuster lives behind the tone ring nut:

The one which was fitted had a ten mm hexagon and was a half nut – it might have been 0 BA at one time and compelled on, however I believe it was the unique because it was cadmium plated, or maybe pale nickel over brass. I made a brand new one out of 0.445″ EN1 hexagon bar, turned with a big chamfer on one aspect to clear the within of the domed tone ring nut:

It really works superbly.

That is it for a bit on W/NG repairs. I nonetheless have the bum pad to make and the dynamo bearing felt to place in, and I’ve to observe the brand new seal within the decompressor. The jury continues to be out on the sphere stand springs – they nonetheless have a security chain on, although it hasn’t made one other bid for freedom since I tightened and retempered the underside spring.
