    Posted: 24 May 2019 at 10:51
Hi everyone! I have recently purchased a 1979 V50 althouthg this is my first Guzzi I have a few other older bikes  and I am used to doing most of the work myself. 

my first question is if there is an alternative to the gas cap with something that is easier to work with and better looking  and not plastic.


Thank you very much in advance

Is that the one you bought? Very pricy.....

My 1082-ish V50 has a steel panel over the petrol cap instead of that plastic thing.

Make a template and make one out of aluminium. Find someone to Tig the seams, insert  a lock barrel, then scotchbrite away....  
that is exactly what I’m about to do!!

The metal flap and foregoing plastic flap fillers are quite different. The mtal version has a metal screw in cap beneath, which is quite smart must be said. The plastic version has what can be best described  as a plastic bung on a coil spring with like a O-ring type of seal, which essentially blocks up the filler hole when flap is closed, ergo the filler hole is more or less a plain hole, with the steel tube beneath, so there's no thread for a threaded cap. The whole thing is really quite nasty.

I was thinking maybe something like this could be used to replace it, but they need the filler hole to be threaded.

Changing the whole tank is what I meant to say but of course could be expensive

Especially when that also means moving the brake reservoir.

The more I think about this, changing the tank might be the better option especially if that is going to resolve the cap issue and the gap that is left behind if you replace the plastic cap.

My 1979 Mk 11 has the standard plastic flap set-up. I agree that it is a pretty Mickey Mouse piece of engineering, and I don't understand why Moto Guzzi didn't just stick with a conventional steel or aluminium filler cap, which would have been classier and surely wouldn't have cost any more.. Having said that, it does the job and doesn't leak even when the tank is full, so my attitude has been to leave well enough alone.

It's also used to hide the brake reservoir. Might have been one of the reasons.

On the other hand, it is Italian.

There's a couple of V50 III tanks for sale on ebay at the moment.
