Good luck with your bike . My mother was the youngest of 5 and the only one born in the USA . The rest of the family emigrated here from Tonsberg.

Have you visited Norway? If not, If you have the opportunity to visit it I would really recommend it. During the summer there are some amazing mountain roads to ride on. Tønsberg is also nice, lots of viking and maritime history.

I ended up modelling and 3D printing a new mounting bracket for the Boyer electronic ignition. If you would like to print one, you can find the file and instructions here.

I got my son in law to print me one of these. Many thanks for sharing the file.

I fitted a new throttle cable from Andover Norton last week. I have only used it on three short trips, but both the end ferrules have split. The metal they are made of is really brittle, almost like glass. The ferrules next to the adjuster are a lot thicker and has not shown the same problem.

I went into a local bicycle shop and got the thoghest brake ferrules they had. These are made of hardened brass. I cut a slot in them using a Dremel, filed them a bit and fitted them back on the cable. Hopefully they will not break like the originals.

I have had some problems starting the bike when cold. Tried a few things, but I figured the pilot jet in the Amals could be partially blocked. Anyways, they do need a clean.

To clean the pilot jet I used a 0.4 mm cleaning needle for cleaning 3D printer nozzles.
