Some people don't recommend soldering connections on bikes because the connection will not flex and some wires, such as where they pass around the forks, need to flex.  If you do this on a section where there is no wire movement then I think it should be ok.

I was under the impression that a couple of layers with heatshrink would remedy this, but I looked it up and ther are different opinions on this. Thanks for pointng it out. I'll keep the soldering to a minimum. Thankfully I've used weatherpak connectors in most of the joints:

I tend to always  apply a small dab of solder to connectors after crimping...especially things like bullet connectors ....basically anything that the wire is pulled on to disco.....

Dug out the brake lines I bought for the bike last year and never got around to fit. The top one is a lot shorter than the one I have on the bike now, which means I don't need to buy a new one. These are made in the UK, and have good review from mid level racers. Probably works great for me. They are priced just below HEL, and I guess they struggled to make money off them because now they sel HEL on their site instead.

Accossato PRS2 radial master with matching clutch lever.  Blue ATE brake fluid matched the blue stripes on the tank and seat nicely :)

Was going to ride the bike home this weekend, but things didn't go well..   Neither of the petcocks I bought off of eBay worked. The short one was leaking at the riveted plate in the front. The longer one didn't leak but it didn't flow well enough to keep the right fuel level in the carbs either, and the bike wasn't really rideable. It really was a big dissapointment, because all the lights and all electronics except the magnetic pickup for the speedo now works. The bike ran well with the small plastic gas tank and all seemed well.. but the last trip of the season was a total of 15 yards :(
But lasted long enough for my brother to take a picture:

The project is now extended for another winter, and I've ordered a few new parts. I've ordered an Italian made petcock and a magnetic bolt for the rear brakedisc. The bolt will be used for the magnetic pickup for the speedo. I've had plans earlier to integrate this into the speedo gear at the front axle. The plan now is to place it at the rear wheel and route the cable in a nylon sleeve together with the rear brakeline. The frequency of updates will be lower for a while as I need to focus on my masters thesis the next couple of months.

On the positive side; the m-unit blue and Motoscope mini is awesome!
