Strange noise on a de-restricted '07 people 50 2t

OK, thanks! I am breathing deeper now. Calming down......

News flash! The regulator wasn't the problem. I'm going to checking grounds and connectors. For the first time today, I noticed my headlight gets brighter when I apply the rear brake. Bummer.

[CROSSBOLT]

Crap on the regulator NOT being the problem! Chasing grounds is good though. Was the higher voltage present with new regulator when you would speed the engine?

I didn't even check. Probably is, but I imagine when I find the wiring fault, that will fix it.

Any news on this, blufx?

I'm afraid not Karl. Not yet anyway. I have to rearrange so I can bring the scooter inside and just ain't got around to it yet. I need to get a move on. I'm gonna have places toi go soon. I'll keep you posted.

Thanks! I really get it! I have so much to do I don't know where to start!

Karl,
  take a look at this diagram. Is there any reason why I can't run a lead from the pulser coil to the ignition coil and run the engine? This is just for testing. I have no intentions of riding it like that. I just want to isolate it from all wiring and hear it run.

P.S. Sending a PM

[CROSSBOLT]

The CDI or ECU modifies the pulse coil output, adjusts for timing PLUS amplifies the signal so I don't think it will produce a spark.

You are correct. It didn't. I have it inside, and all the front wiring exposed. I'm flying blind with overly simplistic wiring diagram, but I think I'm getting close. It's only the rear brake switch that affects the motor running. Also I mentioned my headlight gets brighter when I touch the rear brake, but not the front.

[blufx]

I attempted a quick disconnect of the rear brake switch which only made it more confusing. The reason being I never considered the starter motor safety switches that also double as brake light switches. Besides scratching my head more, now I'm thinking of pulling the starter Bendix just to eliminate that possibility. Neither the teeth of the starter gear or the variator appear to have been clashing, but I can't help but wonder if the starter motor is somehow involved.
Input. I need input!

The two switches on the brake levers are mechanically and electrically identical. Usually the two wires that run from the switches to connectors on the main harness are green and black. The greens go together in the same connector and the blacks go to their connector putting the switches in parallel (OR in computerese) like the diagram. The two wires from each switch are usually housed in a tube or sheath of shrinkable stuff. One of these may be chafed and grounded in the handlebar area. I suspect the rear one is the culprit. If things got wierder could be they were connected wrong at the harness. All either switch is supposed to do is light the tail lamp and energize the starter relay/solenoid. What is happening to make the stop bulb brighter is a mystery to me.

Hello blufx, did you ever remove the stator flywheel?, make sure nothing loose underneath it?  Yes, take out the starter bendix, scooter should start easy with kickstarter, I never use my electric starter, just kick it, so should be able to test for that issue.  Cheers

I think we can disregard that last post altogether. Karl, I'm gonna have to lean on you again. I found something, but I don't know how to interpret it. I can't right now, but I'll post what I found later.

[CROSSBOLT]

You lean all you want or need to, brother! I will await the next message.
