Welcom to the forum, and to the world of proper motorbikes for real blokes. Or something like that. PS: check your profile. You've got a "V&III Racer" according to the "My Bikes" bit. Looks a lot like "let go of the upper case button too late" to me.

That'd be "collateral benefit" then, wouldn't it? That vise looks like a handy piece of kit. Well scored.

Jealous...

I'm guessing, but... I went looking for pictures because I remember the anvil that my father had on the farm in my childhood had similar holes in it. Turns out, the holes have names Gerald G, CC0, via Wikimedia Commons https://en.wikipedia.org/wiki/Anvil#Structure I think the square one in your anvil may, perhaps, be a "Hardy hole" intended indeed as a mounting hole for "Hardy tools". https://en.wikipedia.org/wiki/Hardy_tool Perhaps the manufacturer of the vise offered accessory tools that could be mounted in the hole. Seems plausible to me. EDIT: I found what seems to be cofirmation of my bold theory. Someone asked the same question about the hole here: https://www.reddit.com/r/Tools/comments/8mzd5a/question_about_a_columbian_c44_vise/?rdt=46355 and was directed to here https://www.garagejournal.com/forum/threads/the-vises-of-garage-journal.44782/post-2383317 where there is a copy of a catalogue page showing the accessory.

Thanks for the photos, Tom. @fastaussie was looking for a Champagne Le Mans. Maybe you could get him interested. Yours looks very clean.

That looks amazing.

Hi Tom. It seems that one must be registered on Facebook (not going to happen) to see that. Have you got it listed somewhere else? Not that I'm about to buy it, but I'm sure I'm not the only person in the world who is allergic to Facebook.

Yeah, that happens. As long as you don't have to leave town...

Well done, carry on, that man.

I don't even want to think about that...

Indeed. For a completey unknown band, they had a couple of surprisingly quick successes.

She'll be right mate, no worries... Seriously, though, having a good regulator in the system will keep the volts under control. That, in turn, will keep the waste heat from bad connections under control. The formula is here: https://en.wikipedia.org/wiki/Joule_heating#Direct_current P = V²/R The resistance of the contact is constant, so the higher the voltage across the contact, the more work is done (power generated = heat generated). So keeping the voltage under control also keeps the heat generated within limits.

It occurs to me to mention that it is not only the blade connector that can have a bad contact. The crimp on the wire into the connector can also go bad. A good crimp is theoretically air tight, and should last a very long time. If the crimp is a bit shoddy, corrosion and oxidation can find their way into the crimp and cause a resistive contact. If there are persistant problems with bad contacts (too much warmth) despite cleaning and fettling, I would be inclined to pull the connector out of the socket and check the crimp.

Yes, but the "heat photos" show that it is not the fuse itself that is getting warm. I wouldn't expect that, either, except when the current is getting close to the limit for the fuse. What is getting warm is the contacts in the socket, and that makes sense. All things being equal, that is where the highest resistance in the circuit is to be expected.

The picture is no doubt from one of those "AI" programmes, like Easy Diffusion, where you type in "a picture of a Moto Guzzi on the moon" or something and it generates a picture. I had a play with that a while back. Quite surprising what it comes up with.

Yes, that makes sense. Generally speaking, a contact such as the plugs in the fuse sockets will have a higher resistance than the wires that is is connecting. A higher resistance at constant current will produce more warmth than a lower one. The current through the circuit is constant all the way through, so therefore the contacts will be a bit warmer than the rest. Still, 50°C seems a bit warm to me. Have you cleaned the fuse sockets up?

Check the edit...

His name isn't Wittner, is it? EDIT: found him, I think. https://ferraridentalcare.com.au/ I reckon I remember hearing about him at the time as a front-runner in the BEARS series. The name kind of sticks out a bit.

Hmmm, that would likely look better too. More homogeneous, less grafted together.

Interesting ad, that one. I followed the urging in the text to look at his other articles. Some interesting stuff there, some apparently cheap, including a KR 250 that I would be very tempted by if it was in Germany. I have the impression that the seller had big plans, but that his business idea has gone tits up on him.

Let's assume that the owner cannot, for whatever reason, operate a single track vehicle, and praise him for his humour in making the best of things.

That looks like it has turned out nice. Well done.

Yes, it pays to really look at that stuff when the bike is going back together, really pay attention to what you are doing. I had one where the V35 Imola was "hesistant" at a particular engine speed. Nothing visible, but it turned out that the one plug cap just wasn't quite seated correctly. Another one: in the course of doing something or other under the tank, I had pushed the plug leads out of the way, maybe pulled on one whilst replacing the tank. Whatever, I didn't even notice it running badly, but the next time I looked under the tank I saw the damage. The lead out of the r/h coil was not plugged up properly. It was still sparking, but the shroud that the plug sits on around the contact had been eroded away to the extent that about a third of the material was gone. Cost me a new coil just for being careless.

I hear what you are saying, and agree. Having said that, I'm not prone to lugging a motor, neither generally speaking, nor specifically a Guzzi motor. My first Guzzi was (and I still have it) the V35 Imola. If you don't give the 350 motor a caning, nothing happens. And it begs you consantly to give it the berries. The third Guzzi is a Breva 750, also a small block, and also more than willing to be flogged. That brings us to the V11: it is obvious that the motor is set up to be revved out, and that is one of the reasons I love it. Even so, the way mine spits and farts and carries on can't be normal, I reckon. I'll keep looking, but when, as you put it, I am certain that everything is right and it still misbehaves at lower revs, then I'll take your advice and ride around it.

That's this again, isn't it?
