Rusty Tank Anyone?

Never thought of looking TBH. Might stick the endoscope in there and have a look although the bike is barely 8 months old. I've never had this problem on other bikes with steel tanks. My Z is 10 years old now and no issues. This move to higher ethanol content fuels won't help things though.

 

Higher Ethanol certainly won't help things with it being hygroscopic so effectively attracting water from the atmosphere.

Quite a turn around of OLD ideas in that previously I would have brimmed it prior to a winter lay up in order to avoid or minimise an accumulation of condensation yet tonight I have done exactly the opposite.
Earlier today my 765 was drained of all fuel to the point of not running then one litre was added to allow start up if neccessary or desired

Ethanol, nasty horrible shite

Many years ago when carrying out some fuel research experiments anything to do with Ethanol was problematic. If you think good fuel with glue or honey added you will get the picture!

 

Another tip I've seen (and used) years ago was to add some 2 smoke oil to a pint or so of petrol in the tank and swill it round to coat the inside. Not sure how modern bikes running EFI and loaded with emmisions crap would cope with that. The CAT would probably shit itself.

 

That sounds to be from the same camp as the old brake fluid down the plug holes idea

 

When I had the boat and layed it up for Winter I'd run the outboard out of fuel, then spin it over while spraying misting oil into the carb venturi to coat the bores. The tank was plastic so no problem with rust but required draining due to vapour migration. The Husaberg also has a plastic tank but doesn't get layed up for long periods.
