Leave fuel in the system?

[rikrok]

I just removed the tins to get them all repainted. It will be apart for 3-4 weeks. Should I fire the motor up without the fuel tank to use up what is left in the fuel bowls? Or is it such a small amount and time, it won't make any difference?

Thanks

I've never drained any carbs for storage BUT I always run the last tank treated with Stabil so it's in the entire fuel system. Then I treat the full tank of fuel. In your situation I think Mase has given you the best defense against fuel problems.

In the 14 years I have owned my Valk I have never drained the bowls.  I add stabil or seafoam to the gas and let it sit with gas in the carbs.   In my opinion they may dry out and or stick without fuel.  Living in Ohio I have gone up to three months without starting but during the winter may average 1 month.  Just how I do it.

I doubt a month is going to hurt anything if the fuel is fairly fresh. I store with Sea-Foam in the system and I don't drain the carburetors.

What if one month turns into three or four?

Well, that could happen. Then I'd make sure somehow to get Sea-Foam thru the system. When I store all my junk for the winter [ usually 6 months] there is Sea-foam thru the fuel systems.

My bike usually sits for five months in the winter. I've always used Stabil or equivalent. Most years I've turned off the fuel valve and run it until it stalls. Some years I've just turned off the bike and shut off the fuel valve. It's always started in the spring. With the carbs run dry it takes a fair bit of cranking. I can't remember how much cranking in the spring when it's simply shut off in the fall.

Marine Stabil and Sea-Foam both. Sits for several months in a 40 deg. garage all winter. No issues since she was new in '03. Just saying that combination has worked for me. YMMV

I use Stabil year round. I use a heavier dose for winter storage. Gas starts to deteriorate in a few weeks.
I learned the hard way when bike sat for a few weeks and when I went for a ride it ran terrible. Luckily I ran some Techron through it and it cleared up. Living in Pittsburgh the bike and yard equipment sits for 5 or 6 months and Stabile goes in all of them. Never a problem starting in the spring.

remember to have a full tank of fuel too, it keep tank from rusting inside.
Just as it is done with airplanes.

I use this when I know mine's going to sit for any length of time.
