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?

They are a great way to build a scratch harness with a convenient junction box. But at $370 it is extremely over priced. The $70 "M" button has to used in conjunction with the Motogadget M unit junction box ($300)
Bad soldering creates problems. Soldering was used for decades before crimp connectors.
This one of those things where you hear about the failures of soldering connections. But if you think about how many billion soldered connections are out there and the rate of failure I think you would see is incredibly small. Yes, one is better than the other, doesn't mean the lesser one is not totally adequate. One reason crimping is used over soldering in mass production is the ease and expense of crimping.
Using aircraft as an example is not fair, they have their own issues that need addressing that are not common in everyday stuff.

Skimming the forum after being away for years. In my absence from here I've been working for Revival Cycles, I'm not going to praise Motogadget here but I wanted to mention that there's a lot of miss understanding and apprehension around the m-Unit. we've done 100+ m-Unit installs If anyone has any m-Unit questions concerns feel free to email us a [email protected] and we can demystify it for you.

The only issue I have with the M-unit you can't fix, and that's the extraordinarily over priced cost of the unit.
