There are a couple opinions about storage.  Some like to use a gas stabilizer and others like to drain the fuel...I happen to be the latter, because I usually start tinkering and want the tank and carb to be empty.

This may be of help to you and others planning on the "winter hibernation".   This idea came to me last winter and when I did it, it was like a slap in the forehead...why hadn't I thought of that before?

What you do is pull the vacuum line to the petthingy from the carb and let the bike idle until it dies.  Leave the petthingy in the ON position, too.  The engine will use all the gas in the carb and fuel line, but since the vacuum line is off, the petthingy is closed.  

You then have a dripless fuel line to disconnect from the carb and you just need a gas can with a spout.  Stick the fuel line in the spout and turn the petthingy to PRI to drain (might have to put the can up on something like a box).

Here's the vacuum line....

Welcome.  

This was the first bike that I ever had with a vacuum operated petthingy and it took me 3 years of spilling gas to figure it out.  It was purely a matter of DOH!

I might be slow, but I'm consistent

Short of going downstairs and pulling off my hose to measure it for you, I'd have to guess that it is about 8 mm.

But part of my suggestion is to pull the hose off on the carb end, and just stick that end into a gas can spout.  If the can is raised up on a box or crate you don't need to buy another piece of hose.

I have a 5 gallon can with a long spout that works perfectly.
