Hey,
Seems i jinxed myself, i thanked everyone for the advice and then ran
into more trouble. I blame the internet!
I ran through b-12 and noticed my bike getting more and more juicy
sounding. I roll on the throttle and it gets up and goes. Been loving
it.
Just recently though, i found it went back to how it used to be --
roll on the throttle, feel something accelerating but the bike just
barely trudges forward ... then eventually it'll fall into place and
shoot forward. I assumed it was the carb again because it would putter
sometimes, but after it ran enough it didn't putter anymore so i'm
thinking it's something to do with the clutch?
What other facts and observations can i give to help diagnose this? It
was near 60 today and with stupid traffic my ride was 2 hours. This
happened in all gears (back when i first got the bike, it only
happened in 1st and mostly in 2nd).
I stayed hella warm with my jett vest though ... just pulling my
elbows in squeezes it into me and it warms me all up. Fingers were a
bit numb but still alright - a stark contrast to riding in colder
weather without the vest. (I'll ride in cold weather with the vest as
soon as possible so i can estimate its impact).
And one last thing -- if i want to put the bike in storage, all i have
to do is throw that save-gas stuff in my tank?
Oy!

Listen, it is not possible to give really good advise by "remote control".
If YOU can't tell the difference between a stumbling engine and clutch
slippage, you're gonna have to find someone who CAN........right there in
person, not remotely. Any competent shop will probably give you a quick
opinion for free (or nearly so). While you're there, ask for advise on
clutch (cable) adjustment.

And charge the battery at a low rate for a couple of hours each month or so
(or connect a battery minder).

Your Suzuki is so simple the only thing that can go wrong is the fuel supply
and the carburetors. The only maintenance it requires is regular oil changes,
replace the spark plugs every 8000 miles or so and check the valve clearances
about every 10,000 miles (regardless of what it says in the manual).
Your current problem is probably just crud in the fuel system. Each
carburetor has a float bowl drain screw and you can loosen the screw and
drain the fuel into a clean rag. If you see rust and water in the rag, you'll
know it's coming through the system and plugging up those critical tiny
passages and jets in the carburetors.
The vacuum-operated automatic petcock has two standpipes inside the gas tank,
a long one for the main fuel supply and a shorter one for the reserve fuel
supply. Crud and water will naturally accumulate in the bottom of the tank,
and when you select reserve because you just ran out of gasoline, the crud
will go down into your carburetors.
If the vacuum hose going to the petcock develops a split, you can have a
vacuum leak and the petcock will automatically close on you. But it's easy
enough to switch over to the REServe position to see if you're having petcock
problems.

I hear you and i remember you suggesting that. I'll take care of that
and post back. In the meantime, riding, if i tap the clutch in a
little and back out a few times, it'll snap back into gear (for real).
That's a bad way of describing it. It's just strange that this problem
should present now, after running through the b-12. Maybe it loosened
up the gunk that's now reached a more vulnerable spot.

I was reading a website that said that, unlike the Intruder models, your
engine has only one
carburetor and that it's very cold blooded and takes a long time to warm up.
http://www.motorcycle.com/manufacturer/suzuki/suzuki-intruder-volusia-800-16519.html
I was looking at the parts list for the 2003 Volusia and it listed PILOT JET
(27.5)
That's the smallest pilot jet I have ever heard of on an engine that size. If
any crud
gets sucked up into the pilot jet and idle passages it's going to cause
problems.
But the parts drawing at
http://www.powersportspro.com/pages/parts/viewbybrand/default.aspx
does saw that the idle mixture screw is externally adjustable once you remove
the plug.
4 ADJUSTER
4A PLUG
Turning the adjuster 1/4 or 1/2 a turn counterclockwise should work wonders
for the cold blooded nature of your motorcycle.
