Yes I mounted the Mosfet VR on my13 v7 special with guzzi brand engine bars. I used the stock mounting holes and elongated them with a file.I also used short spacers on6the mounting bolts so the wires from the VR do not touch the front engine cover
Maybe my logic is faulty, but I'm prepared not to care. Yes, maybe it's a bit hot. But I don't really trust a motorcycle battery after 2 to 3 years anyway. In my view, spending $75 for a fresh battery on a regular basis eliminates a lot of electrical problems and minimizes my worries on the road far from home. Heck, based on what KevM has found, it's not clear to me that this performance is even out of spec.
I have a 2012 V7R which is showing 15.1 volts. Can anyone confirm if this is cause for concern? I am confused by all the posts.
Ok, another data point. I've got a 2013 V7 Stone with 40,400 miles, and original battery and everything else stock.After a long ride with engine and everything else stinking hot, I'm showing:Idle 14.0 volts. 15.37 V at both 3,000 and 4,000 rpm. Main ground and all other connectors I'm aware of are known to be clean and tight. Just did the spring time DeOxit and tightening.Maybe my logic is faulty, but I'm prepared not to care.

SmithSwede, I'm with you, the jinx is in! Based on my findings for my bike, I'm going to keep the stock VR and take my chances.
OK, so cold start this afternoon gave me 15.4 Volts from 1-4k rpm.I figured I've had it for years and it's probably always done this, so I took it for a ride (to drain the fuel a bit, I figure it's probably easier to pull the tank to do this anyway, and I might as well replace that fuel filter now if that's the case).When I got back it was reading 12.8 volts at idle, but still 15.4 anywhere above that. I need a voltage regulator, and I'm starting to believe I won't be alone.
Well, I had to replace my battery yesterday. The bike is 2 1/2 years old. After being fully charged (Battery Tender charger) to 14V the bike sat for about a week. When I pushed the start button nothing happened...no click...nothing but some lights. My meter showed 11V. The battery shop agreed that this was probably due to being over charged for a couple years. With a sealed battery you can't simply pop the caps and see if there is a problem. Now she fires right up.
Now might be a good time to replace that VR.
Ha, ha, but he did. At about 5k but the damage to the battery was already done.
:1:. Others seem to think that it's OK to have a R/R charging the battery at +15V, I do not share that opinion.
From the service dept where I purchased my bike FWIW.Bob,We think Guzzi installed that higher switching voltage regulator/rectifier on purpose. They are all like that. All measure same. There was no way to expand the alternator size because of the wheel and casting positions so they bumped up the voltage of the zener diode gate switch. Yeah, poor substitute but it was cheap! You can go back to 14.6VDC reg/rec if you want but in our opinion it doesn't resolve anything really.
