Well, after the 4th tank in a row of gas, my fuel sending unit is doing the same thing reading erraticly. When working properly, it would drop one bar every 30 miles or so. Lately my gage will drop one bar between 48-60 miles and stay one bar down through 90 miles and will then drop 3 bars down and back up sporadically(over a short time period not quick) to one bar down, then to 4 bars down then to 3, etc. It does however seem to be still fairly accurate with only 3 bars left and down. I called the dealer today to let them know and was told they just need to call ktm to let them know whats going on and they would get back to me. So it hasn't been set in stone, but should be taken care of under warranty. Unless that part is also on backorder like everything seems to be for the 1290, then I'm just going to wait till it comes in and have them do my 2nd clutch cover(with the bearings) replacement and the fuel pump unit together. The clutch cover gasket had been on backorder since the end of september and came in around 4-5 days ago.

Y'know JR, I could pretty easily imagine that to be "normal" behavior. If you're doing pretty much anything besides straight line droning, there's gonna be a lot of turmoil in that tank especially when partially filled. So, unless you've experienced different behavior from this guage when driving the same route and at the same enthusiasm level, you may not get much satisfaction from replacing things. I've never seen really ideal bevavior from any bike fuel guages but they generally do the job of letting you know when to start worrying. I still use the trip meter for my cut-it-close adventures...
