This is what you and I are talking about.  Also helpful:

I've used both, albeit I got mine from Dennis-Kirk a while ago.  Gauges are safer, and more durable.  I need to get another of the latter, mine got stolen off of my Bandit when I stopped for the night in KS on the way back to CO 2 years ago.

Yes, and the "Bouncing Needles" is caused by the little "check" valve on the line being open just a little too much.  You need to tighten/close the valve until the needle smooths out.  Allow less air thru the valve and slow the reaction of the needle.  It still draws the vacuum, but not as sporadic.

Wherever and however these are aquired, they are universal.  Of course, YMMV, and this wouldn't be aimed at the CBMMA.  I've got a tool that will fit right into that category, with my Bowl Float Level Gauge.  It's a piece of tubing that fits on the bowl drain, as is marked over a 10mm span near the opposite end, like a vernier flask(?).  You make it a tool by putting calibration marks on with a pinpoint Sharpee, or some such.  Put it on over the drain, and open the bowl drain screw, and hold the top mark at the reference point in your manual.  Read it back down counting off your marks to see how many MM the fuel is below that reference point...or if it is over.   :o  Use that to set the floats.

I made this tool when I was TShooting carburetion on a 1993 XV750 for a friend.  We'd done rejetting, idle mixture and float adjustment, but until I actually saw what was happening in the bowls, and made the necessary adjust to the floats, did the bike finally stabilize.

Cost of tool:  I dunno, how much of any size tubing in a 6-8 inch length cost?

This "gauge" is used with the bike running, and can gauge the fuel level at any RPM.  Suspect fuel starvation?  Easy way to find out.  And it is done without removing the carbs or anything else.

There are directions for making the float bowl level 'tool' in the Haynes manual.  Cost would be under a buck.

That would be obvious.   ;D

Didn't have a Haynes with me at the time...had the FSM.
