This may be of help

I filled up my Tiger 955i 04 plate the gauge only showed 3/4 full but the tank was brimmed.

I took the tank off and removed the bottom plate and took out the fuel mechanism.

It consists of a long tube with a cap on the end, I removed the cap.
The inside of the tube has a long thin curcuit board with a float that shoud move freely up and down as the fuel level changes.

The float on my bike had got wedged 3/4 of the way up the curcuit board.

All it needed was a slight tap to the float and it became free, this fixed the fuel gauge problem. It also happened on a friends tiger, I think pulling the odd wheelie can cause this to happen!

If the sensor was the early type (ie the float is a white spongy material) this happens a lot. The later one with a dark grey smooth float cures all.....

And getting the old ones "un-stuck" is temporary. it will get stuck again later. You can replace the float in some cases, or replace the sending unit with a new one or eBay one from a 2006.

My 2006 is starting to show full and then dropping to empty w/ the fuel light coming on and then back to full or the correct reading. What's with that?

It seems like I've seen someone complain of that before. The float slides up and down a circuit board. It's possible the contacts are corroded or fouled up somehow but that's just a guess.

There aren't any contacts - the float has a magnet in it which actuates a series of reed switches varying the output resistance.

Yeah I remembered that later.

I actually think that float is bobbing with fuel movement in the tank, then getting stuck now and then. But I thought the 2006's had the updated float in them.

Have you checked your electrics? Often electrics problems show up first as weird unexplainables. My recent issues with the output from reg/rectifier were relatively sudden and heated. The meltdown at Madame Toussauds... and so I have 10 gauge wire from R/R to battery now, but I digress. Check fuses and wiring for issues.

This has happened to me 3 or 4 times! It started in the extreme heat in Spain on a recent tour of the Pyrenees. Just after brimming the tank, I noticed the fuel guage dropping alarmingly, the warning light on and seconds later, it all bounces back again. at the time, I blamed the extreme climb I was on immediately after filling up but it's happened about three times since (once in the UK) and I'm not sure it's related to the angle of the dangle anymore.

All electrics on the bike are good. I regularly run additional lights, heated grips, satnav, heated insoles and heated gloves for pillion, though never all at the same time & I've not done the charging bypass mod either.

It's not really an issue (yet) because it self-fixes but I'd like to find the cause sometime.
