Truly amazing photo, absolutely digging the color of the RD!

Turning Wrenches / Re: RD350 with Powerdynamo help
July 31, 2023, 12:36:41 PM
Many thanks, that link was very helpful. I've moved around some wires, thinking possibly the relay wasn't grounding properly. Also, think I found the source of the air leak: I'd removed the oil pump to go with premix and hadn't blocked off the oil intake on the carbs (read on another forum that had caused a similar high revving). I'll get those blocked and retry!

Turning Wrenches / RD350 with Powerdynamo help
July 25, 2023, 07:23:19 PM
Let me preface everything by saying I have very little mechanical experience and even less electrical. I've been learning as I'm going, and this has been the biggest project I've faced. I WILL ask dumb questions!
I inherited a 1973 RD350, somewhat of a family heirloom, and the bike I learned to ride on, so a big deal. It was completely disassembled and given to me to put back together.
The old regulator/rectifier was causing major issues, so I got a Powerdynamo kit installed but I've run into a few issues. I would really appreciate any insight, I'm probably missing something really obvious. Most everything is put back together - the bike turns over (yay!) - but...
1) Once the bike kicks over and starts running I can't shut it off! The stock kill switch is no longer attached to the coils - all there is now is a blue wire that runs from the new coils to a relay. The relay integrates into the old wiring system just after a fuse that comes off the positive from the battery. Even if I detach the blue wire from the coils to the relay, the bike keeps running. I'm not entirely sure how the bike can even run without power from the coils??? Shutting the ignition off does nothing as well. The only way I've found to shut the bike off is to shut off the fuel to the carbs and let it run itself dead.
2) When the bike starts, it revs up super high and stays there. I thought at first I had the throttle cable tight but I've adjusted the carbs and the cable, and still nothing. It jumps up like the throttle is wide open and won't settle down to idle.
3) I've got the stock electrical system wired up correctly to my knowledge according to every diagram I've found. The only exception to this is the new Powerdynamo system, which I believe I've integrated properly (although, there've been a few points I feel like I'm guessing on the new system. The German to English translation leaves me scratching my head at a few points), and I still don't have any lights. None at all.
I can post some specific pictures of things if needed. I'd really appreciate any help I can get!
