Ha, that would be great - unfortunately I’m short on time space and indeed skill to do that!

f you remover the filler cap and the base it sits on you should be able to see inside like this

Carby tanks have a less generous filler opening than the ie bikes though.

When Monsters went to injection, an extra ring was added to the filler cap and the aperture opened so the pump would in, along with the filter and a portion of your arm.

I removed the filler cap and it made very little difference to access, sadly.

I didn't realise there was such a difference - what damned nuisance!

POR15 highly recommended - used it on an old Guzzy tank 10 years ago - still OK!

Also still present on workshop floor !!

You could leave it dry in the sun to dry out for a few days, then steam clean the inside, then fill it with a strong detergent soloution for a few days, then drain and steam wash.
You still might not remove the residues in thicker 'varnish' deposits.
All you need is the equivalent of a teaspoon or less of fuel or anything vapourised to make an impressive bang, it will also reshape the tank a little.

That really leaves you with a few options which are:
Sod it, clean as well as possible and hope it is clean enough (or get a specialist to do it)
++ Expensive and potentially dangerous, potential for local distortion of the tank during welding. Will need a respray afterwards so the rest of the bike looks even worse so you end up having to paint everything,

Clean it as well as possible and tin solder in a patch, no a teeny Halfords soldering iron isn't going to cut it here. You need big copper or steel bits and a big heat source to get them up to temperature.
+++ Very old school stuff and a right PIA to do using very big very hot lumps of metal to provide the heat and a mini forge, big propane burner or oxy-acetylene to heat your bits (Oh and very thick welders gloves). Still need to do a bit of filling post fix and respray so again that will lead to more re-painting.

Clean it as well as you can, rattle a few rocks around the inside then treat the porous area with some rust remover stabiliser and then (as per Chriswilly) seal the inside of the tank with any of the fuel proof epoxy sealers. You'll get a 1 - 2 mm layer of epoxy over the leaky section and stop it recurring anywhere else. Any of the now treated rust acts as a reinforcement for the expoxy so it will be much stronger and stable.
+++ Easy to do, very limited skills required and a pretty permanent fix. Probably just need a local touch up on the tank when you've done.

Thanks for all the help so far!
Next question (said wearing a reinforced hat and from behind a shelter!) as I’m getting it resprayed - what colour? I know red is the best and fastest (obviously!) but I’m thinking a change may be good...
Let the abuse begin!

Paint in haste, repaint at leisure

That’s ace, I’ll be stealing that one!

The silly part of me thinks the new orange - as sported by the new Superleggera - just because!
How about red with a white stripe along the length - especially if I can find the seat cowl?

I quite like white stripes...

Hi Jez,

I like the look of that. Do you have a side on picture you could post please?
