Petrol gauge - daviee - 28-03-18
Hi don't no if this has been asked before but is their a cure for the petrol gauge rising when you twist the throttle mine will show a Lot more when you twist the throttle as in it creeps up
Re: Petrol gauge - Disorderlypunk - 28-03-18
does this even happen when the bike is standing still??
as strange as it sounds you might want to start at the battery with a multimeter and see what the voltage across the battery reads as it is running and gets reved
think of it this way - if your regulator is goosed it could be firing too much power into the electrical system at higher revs and that extra power going through the variable resistor in your fuel guage could be pushing through more power and making your guage rise higher up
running with everything off (lights heated grips etc) you should have a reading of 14.** volts @5000rpm
- it is unlikely but it is certainly possible and worth checking as it can cause more issues further down the line
after that i can only think of a dodgy earth somewhere in the circuit (unplug and clean connections)

Voltage is bang on I run a volt Gauge it as part of the dash I have herd of a few doing the same but not come across a cure for it

It doesn't answer the question from Punk. Does it do it with the bike standing still or only when moving?
Re: Petrol gauge - fordlatch41 - 28-03-18
Mine does this when moving, rises under acceleration and drops when slowing down, it's because the fuel rushes to the rear of the tank (where the fuel guage is) when the throttle is applied and rushes to the front of the tank away from the guage when slowing/braking.

would need to check but its hard to hold the throttle when in nutral with the engine running but will try it with engine off with mine its not the fuel going to the back of the tank that would only do it on the initial opening the fuel would settle again , if i am in top gear and do it at very low speeds you dong get a massive surge but it still creeps up

I wouldn't worry, It's just the tides :evil

Re: Petrol gauge - Disorderlypunk - 28-03-18
fuel guages are not all they are made out to be anyway - chop never had one and using my cheap chinese koso i only have a F**k about to run out sensor, fill her up every 80-100 miles and you should be golden (im not running standard intakes and ride like a twat on long rides and easily do 100 miles + running around on a tank)
Re: Petrol gauge - tommyardin - 28-03-18
Might also be just vibration
Re: Petrol gauge - tommyardin - 28-03-18
Especially as it goes up and down with engine revs, and Davie says it's not fuel surging back and forth the acceleration and braking
Re: Petrol gauge - celticdog - 29-03-18
I wouldn't worry too much. The petrol gauge is about as useful as a chocolate teapot or that ashtray I fitted on the front end last year.

That was your big mistake Celtic, never, ever, ever mount an ashtray at the front of a motorcycle, firstly the ash can get in your eyes and the embers could worse case scenario could set fire to the fuel tank. Mounting it behind the rider is by far the safest bet, but I hasten to add not the most convient.
Anyway my ciggy lighter will never stay alight above 15 mph.
Actually I don't smoke, unlike my little Honda C90 that needs a rebore.

I knew I'd done summat wrong Tommy :lol I've also given up the dreaded weed many years ago and feel all the better for it.
Geoff Towers is the man up north if you don't fancy doing the rebore yourself-
