Check your fuel taps

[EncinoBoy]

I'm looking at the original taps from an early 80's Ducati which are virtually identical and they offer a
reserve position with the "RES" stamping faintly at the 6 o'clock position on the plate. My guess is that
the description is just lax...

The late LF Harris Triumph 750's made after the original Triumph company went bankrupt and from about 1983 to 1987 have an Italian fuel tank and the same fuel taps as a Laverda. So any shop who sells vintage Triumph parts will have them. They are also much cheaper than buying from an Italian bike shop for the identical part.

Here are some on Ebay

Those are not a lot cheaper if you live outside the US and aren't suited to twins. They look wrong.

The spiel says 'the positions are on and off' ... surely there's a reserve position???

Looking closely at the central rotating part of the tap, there's no Reserve position, so the description is correct...

Just use one tap at a time and hopefully there’s some fuel in the other side of the tank….unless you’ve been going around twisty country roads…don’t ask how I know!

Surely, the fuel won't move to one side, unless you're cornering with the bike upright?

Assuming you don’t brake, accelerate and the tanks centre tunnel doesn’t taper to the rear. No baffles in a tank, fuel sloshes about all over the show, if you brake/ slow into a corner all the fuel will rush up front ( out the fuel cap!,) then find a side of the tank as you start to lean, more so as the fuel level goes down. My Morini has a two tap setup up, windy little Exmoor lanes, mostly going up, started to run out of gas, switched second tap- when I checked the fuel it was almost dry- it’s a bit like shaking a tank to get the last drop out. I literally rolled into a garage on fumes.

That's the technique used on both my Falcone and the Vincent where the tank is separated in the centre to a certain extent.
Open only one tap, the other serves as reserve.

Yep same as the Norton Commando's

I new a Shirley, and her reserved position was missionary. Quite striking and talented as well. Memories

How serious is this? There must be at least a hundred of these taps in use. Never had an issue with mine other than needing to get used to the shorter inner hose. Having the taps stop functioning on a big trip would not be fun.
