I have drained the tank and brought it inside for the winter. I know this is not necessary but these petcocks leak and I don't want varnish in my carbs.

My question is, what should I do to the inside of the tank for over the winter?

I have read that you can slush some engine oil around in there. That way it will not rust. Rust is supposedly the main problem (unless ofcourse you are worried about the risk of explosion). When you want to put the tank back on, you just slush some petrol around to clean out the oil.

I do just the opposite. Believing that fuel surface area and air in the tank is what causes evaporation and degradation and spoilage of fuel I fill my tank to the max with stabilized fuel. I also take advantage of moderate temperatures (like the 60-degree day last week) to take my bike for short 20-30 minute rides, freshening the fuel in the system. I have never had any leaks of any kind, not even when I leave the fuel tap on which I do during the warmer months.

I fear draining the bike without a means of complete drying will result in a film of fuel which will quickly evaporate and leave the dreaded varnish. I may be wrong, but that's how I see it in my mind's eye.

I thought the inside of the gas tank was already coated with a rust inhibitor (?).

This is what Id as well - but I haven't found it warm enough yet to go for a ride - and besides with the amount of sand & salt they lay up here in CT it would mean a 30 min ride followed by a 1 hour bath and wipe. My bike is winterized perfectly now and clean as showcase so I don;t want to go through the trouble of re-cleaning it and then in the spring find the places I missed filled with corrosion.

The petcocks on these bikes leak.

I have completely drained the float bowls only to find them full again 2 weeks later.

Just dont do what my mate did recently and fill it with diesel!

Why not? If I could get half the torque my F350 has, I would be in heaven...

Hey, Jose: I think it is a mistake to do what you did, but if you are worried about condensation in the tank now, you have some options : drop some of those moisture absorbing crystal packets in the tank? A better option is to fog the tank inside with fogging oil. Swishing around motor oil in the tank will do the same thing, but its hard to get everything covered that way.

Also, did you run your carbs dry and then drain them when you did this move? Otherwise they will varnish over anyway. And, since your petcock is leaking I would recommend replacing it, or get a refurb kit for it.

My suggestion would be to put the tank back on, fill it with gas, add Stabil and run it until the stabilized gas is in the carbs and quit worrying about it. One advantage is that on the good days that pop up now and then in the winter you can ride the bike and enjoy it.

This isn't a scientific recommendation but it has worked for me for 54 years.

I keep 100LL aircraft gas in my occassional use generator. Airplane fuel is very stable compared with auto gas. However, don't do this with an exhaust system that has a catylitic converter as the lead in the fuel will do it harm. So, filling the tank with aircraft gas, which you can get at just about any airport will probably keep it from going funky for a pretty long time.
