1977 RD400 Cafe Racer conversion project

I am just starting to convert my 77 RD400 into a café racer. I have it all stripped down and am taking it to powder coat this week. I have heard of the "M" Button wiring kit to help me put it all back together with new parts. Have any of you used the M button wiring system on your bikes?

You'll certainly have your detractors about the M-Unit. Check out Motogadget's and Revival Cycle's websites, and see if the features make it worth it to you. I use them on my builds, and have no regrets. It's a one time purchase that I consider a nice upgrade.

You can buy a lot of solder and shrink wrap for $400 ($500Cdn). I'd spend the $35 on the harness and shorten what needs to go in the headlight casing.

Soldering creates areas of potential failure. Pro quality crimps are the way to go. You won't find soldered joints in the miles of wire in commercial airliners.

Bad soldering creates problems. Soldering was used for decades before crimp connectors.

We also make airplanes out of metal now too.
Except those that are composite or tube and fabric.

Very few wood and/or fabric being made these days.
Two of the best back country aircraft, Aviat Husky and Maule, are tube and fabric, as are a bunch of LSA.
