Re: Wierd problem with 5th gen VFR
if the brake light is causing this i'd guess on a short. if the draw of the brake light is enough to cause a stall and you want to prove out it's not the draw of the brake light pull out the front signal lights or possibly a head light and leave the brake light in. it's also easy enough to test the r/r with a multimeter.
if you need an r/r i recommend rrstator, they are a canadian company and their r/r is about 1/3 what honda charges. not as cheap as the ones out of china on ebay but you know where you're buying from. they have sales on ebay cheaper than their web site

Early fuel injected Blackbirds were prone to a harness plug corrosion issue that would cause things similar to this. Does anyone know if the VFR had any similar issues?

Yeah, the VFR's had corrosion/melting issues around the Stator, Starter Relay, and R/R plugs.
Re: Wierd problem with 5th gen VFR
I've had problems with those ground consolidation points (big orange connector) on other bikes, but yours doesn't look bad at all.
I don't "see" any problems in your pictures. Did the mechanic find (and solve) the problem?

The problem is somewhere in the circuit for the running lights, because as soon as any light is plugged into those sockets and turns on (the running light) it goes from 14.6v charging to 15v.

That is a significant clue.
The problem is not in the lighting circuit. The problem is in the common ground. My guess would be that the ground has failed in another circuit and is grounding through the lighting circuit and that ground is overloaded. That orange connector you have could be the problem; check the Voltage at each pin with power on (use mV range) should be less that 100 mV (to battery -ve). If the Voltages are unequal, there is a problem in the connector. If the Voltages are high, but equal took towards the frame ground.

Left him a message asking him to check that, thanks :) hopefully that fixes it, this bike has been out of commission WAY too long :(
Re: Wierd problem with 5th gen VFR
All of them are like 0.4-0.7mV he says, just checked them. Also cleaned all the grounds except the one at the back right corner of the bike, that is impossible to get to without disassembling the tail section.
Re: Wierd problem with 5th gen VFR
Stator turned out to be bad...27v on one phase, 45v on another, and about 80v on the last one. Could this be what is causing the problems?
Ordering a Rick's stator Monday, unless RM stator is better?

No.
Did you try running the bike with the stator disconnected? Did it make a difference?
No, it didn't. A defective stator would cause charging problems.

Ah. Well the stator needs to be replaced anyways, no biggie.

Going to take it back to Rosey Toes, as this is what the bike was doing before I bought it and they were supposed to fix. (their fix did work, for about 8kms)

Edit: He took it out for a ride today, said it worked perfect for about 30 mins then started to bog out and die. Fuel pump?

Sometimes while running the multimeter would read 0v off the battery then it would go back up to 14.2v. Hopefully a Canadian Tire has the battery in stock, so I can swap it.

Only starts with the kickstand down and the bike on its side, if I bring it up to riding position while it is running it instantly dies. If I turn it off then on while in riding position and hold the kickstand out with my foot to simulate it being parked, it runs perfect. Kickstand switch? Brought it to Ontario Cycle Salvage and they said it seemed to be ok.

K How many shops have you brought your bike at? 3? Why do you have it in your possession? Do you take the bike back broken? I dont understand.
Dont take this the wrong way but you need to find a shop and a good one and bring it there and let them find it. Your changing everything on that bike everytime you hit an issue. You went from a battery to an RR to an harness to plugs to switches and everything in between.
Bring it at a shop and leave it there till they fix it, I dont understand how you get it back from shops if it's not working? You towing it around to get different opinions? and trying stuff at home after?
Re: Wierd problem with 5th gen VFR
God d*** man, It's amazing you still have hair on your head I would of lost it all by now lol
My guess is it's in the wiring harness. I mean you have way to many here and there problems. my guess is you cant notice it and it's shorting somewhere. like if it would only do one thing it would be simple but you have so many weird little issues that it's got to be in the harness somewhere.
make sure you stick a new set of plugs in when you try starting it after just in case it fouled them again. Running rich as it's dissadvantage lol

The plugs in it are pretty recent, so hopefully they did not get ruined again haha. Right now the issue is it overcharges when bulbs are plugged in to the running light circuit, will update if issue is still there once the stator is replaced.
Re: Wierd problem with 5th gen VFR
Stator replaced but he now discovered the cover had been well messed up by the last owner. Found weld fixup spots, and I think caulking too. Told me when he replaced the stator it was hitting off of the flywheel rotor? Ordering a new OEM cover/gasket tonight/tomorrow.
Re: Wierd problem with 5th gen VFR
Cover replaced, waiting for final word :) Hopefully this bike has been fixed...
Re: Wierd problem with 5th gen VFR
I got my fingers crossed for you.
