V7 Charging issues / Dead battery -- PLEASE READ

My wife's 13 V7 has had a bunch of trouble with the mufflers completely burning up. first the left at 1500 and now the right at 7500. When I picked it up the never before seen check engine light came on. They kept it there another couple of days and said it was the cam sensor code. Could this voltage regulator have been causing all these issues ? When I say the mufflers burned up they turned glowing red at the connecting plate.

Cam sensor issue may have impacted timing. Retarded timing will cause an engine to run very hot. Your headers should be purple as well. If the headers aren't purple, then you may have had excess fuel burning in the exhaust which is un-related to the cam sensor issue.

I was riding around last night(80 degrees out and beautiful) and her bike is still running like crap. I think I'm beginning to see some discoloration to the left muffler now, Ugh. Never had an error code until I took it to the dealership.

The one it may likely have caused is the cam sensor. At least that is inline with the others I've documented. What is the idle voltage at the battery? From memory, the muffler issue could be a faulty map. I recall an extended open injector dumping fuel, fixed with a new map. Are you going to T.O.? I'm not too far away and can help you as needed.

You're welcome!

One small note: The upper and lower attachment points on the frame are not quite parallel.
When I tightened down the mounting plate it bent every so slightly.

My original plan was that the VR would rest on the heads of the lower plate attachment screws and on 1/4" spacers between the VR attachment screws and the mounting plate. This was a perfect fit on the mockup, but once everything was tightened down, the VR was only supported by the VR attachment screws.
 
Hi all,

Found this thread after I started a thread wondering why I burned up a battery.

TL;DR, maybe the VR, maybe bad management on my part. Here's the skip to the end highlight with follow up question:
===
The possibly bad news is, the multimeter is saying 14.99 at idle and 15.28 at 3-4000 RPM. That article I linked above says the idle was over 15 and at 3-4k it was 16 to 17 volts.

Granted, this all happened to a bike with exactly 450 miles on a 3 year old battery (I bought it 2 years ago on a year old closeout). It's possible I killed the battery by leaving it hooked up in the bike without a battery tender all winter (my garage doesn't get colder than 45-50° in winter).

Does that sound like a bad regulator or just bad motorcycle off season management?
===

Burned up? If you mean it doesn't hold a charge any more, just note that newer AGM batteries only last 2-3 years these days when perfectly maintained and put into service correctly (most are not). If you are using a battery tender style maintenance charger, best to not leave them plugged in all Winter. Only plug them in for a short burst every 2-4 weeks.
Lithium batteries are leading the way; https://www.guzzitech.com/store/product/antigravity-battery-bs12/ - expensive but I'm at nearly 4.5 years using them on my personal bikes, and I have yet to put even one on a charger.

Sorry, not actually burned up. It was down to 3v and wouldn't charge.
At this point I'm willing to assume it died due to age and mismanagement by me.
At the next service (first service) I'll have them check it.
 
I bought my 2015 V7 Stone used about 6 months ago, 3400 miles, and luckily inherited the warranty. I've put another 1000 miles on it. Just found this thread and immediately went out to check my charging. 15V off, 15.5 at idle, 17V at 3000rpm. I called my local Guzzi shop and they said they'd take it in and it *should* be covered under warranty. They're ordering a new regulator/rectifier from Italy, said they have no way of knowing when it will come in. Just want to note this here to ask if there's anything else I should make sure they check for? I'm surprised it lasted this long, but I have no idea if there were any electrical issues before I got it.
Thanks in advance for any input.

I know many didn't wait for a warranty and bought their own to get it taken care of. Yours sounds higher than most I have read about.

I hear you. Guess I want to take advantage of the warranty while I have it. The wait is a drag. Are there other checks I should perform on my bike to see if damage was caused by the overcharging?
 
My V7TT stopped charging recently, stator was not outputting anything, with the exhaust off and front cover removed the metal tab that the wires are tied to had fractured and pulled the wiring against the stator case.

This was shorting one side of the stator to earth

Might be worth checking if you have time.
