To drain or not to drain, that is...

The newly purchased Vulcan is going to sit for 2mos. A lifelong friend is an actual motorcycle mechanic. He says I should drain the carbs.
The bike sat for 3+ mos before I bought it. I recently rode it for 7 mi, it ran fine. I own 6 or 8 vehicles, all but my GN are carburetor. I only start/drive them a couple times a year. Since 1988. No real problems.
I keep seafoam and xylene around all the time.
Opinions?

Stabil fuel treatment would be ok for a month or two IF your fuel system is COMPLETELY[/B] sealed from the atmosphere (incluing the float bowl and tank cap vents.) The 10% ethanol that they put in gas now absorbs moisture and gums up. Sure, usually you can get away with several months, but a carb cleaning is not pleasant on our little V-twin.

Just put the drained gas in your cage. You still need to seal up the fuel tank- don't want it to rust!

They are drained. Not much in them. Makes me wonder about the float level. I don't know how much longer I will have internet. Supposed to go of the 26th.



Once again, thanks wolfie and kelly.

If you are still online,you still need to fill the tank and add stabil or seafoam or both,will keep your fuel up to snuff for a couple of months and retard tank corrosion /rust.Fluctuations in temperature will cause a lot of condensation in an empty metal tank.

^^^What Denny said, fill it up to max and sit it out. If you feel the need in a couple months, drain it out put in the cage and fill it back up with fresh again. In my opinion, less condensate, rust ect.

04-3,200 miles bought July 2011 with 928 miles. Loaded with acessories to many to list here, see my albums for more details! I also make a custom tank bib specific for the 750 if anyone is interested, ck my albums for some pics.

Thanks fella's. Tank shows about half full of what has to be old gas. I will try to get a jug of gas and top it off. See if I can make a bigger mess.
On the internet, just don;t know how well ATT has their act together. Where i'm going the internet is government controlled pretty much I understand.

True about the condensation...but if empty, and the cap is left open, there can be no condensation. Think about a condenser on a still...gotta be almost airtight to work....An empty tank, left ventillated will just dry out. I did it on mine before fixing the holes in it.
