"Prior to 2014 the RT analog gauges were worthless, they tended to bounce and they didn't give you a good idea of how much fuel you really had. The gas gauge on the 14 and newer are pretty darn accurate. "......
There's no denying that after 2013, the fuel gauge accuracy got a helluva lot better, at least as far as the bouncing around & wildly innacurate readings were concerned; but sadly, even tho the 2013 & earlier digital 'bar graph' is more stable & better reflects the progressive fuel use, I've found that the sender itself is really,
REALLY inaccurate too, and even tho the digital gauge now shows a progressive reduction from full to empty as I ryde, it NEVER shows a true 'Full', and when it hits the bottom bar and the fuel light comes on, I invariably still have
AT LEAST 1/2 a tank of fuel left....but it's still never the same 'progressive fall' from full to empty either!! :shocked:
Sometimes, it says it's only 3/4 full when the tank won't hold another drop, then it dives to empty and shows the low fuel warning light after just 35km of ryding; other times it sits on full until I've ridden 200km then suddenly drops to empty/low fuel light in the next 10km; or the bloody thing starts out OK & even looks like it might do the right thing as it slowly & fairly accurately follows my fuel usage over the first 1 or close to 200 km before dropping to empty/low fuel warning light status soon after & a dip of the tank shows it's still close on or above 1/2 full!!
So these days, rather than using the appallingly inaccurate analogue gauge, or the slightly more accurate digital gauge, I just work off my trip meters!! Since I had the Rotax Racing ECU Upgrade done to my V-twin, it's been great - Cruising solo or 2-up, a full tank is generally going to be good for something over 400km; fanging it around the Hills or playing boy racer with the Highway traffic it's good for about 300kms; and that's a whole boat-load better than it was before & quite respectable for such a wind-jammer of a bike! Besides, the trip meters are consistantly accurate and have never varied in their 'rate of registering the kms' - altho I must admit that sometimes the 'reported distance travelled' doesn't really reflect my actual 'distance made good' over the ground, despite accurately reflecting how many times the rear tire has turned & how far it has 'theoretically' travelled - but usually if that's the case, then the speedo may also have said I was travelling at about 90 kph for a bit while the byke was barely travelling at a walking pace!!

pps: Oops, my bad!!

But it is fun!!! :thumbup:
