Not a service item now either is it, fire brigade maintenance. Good plan to give it a clean occasionally as you did.

I assume the float is in the body of the pump  :187: did you manage to free it up before putting it back in the tank?
Have you taken it for a ride yet to find out if the fuel gauge is working ok  :027:

The float sender appears to move freely when I had the pump out

Its made from thin copper tube and looks delicate

I didnt mess with it as i did not want to bend or break it

Have not taken the bike for a ride yet but hopefully the zip tie may assist in preventing the float from getting hung up on the pump wires... I am doubtful

hi Zevk
I know this is not top of the agenda at the moment with your current rad issues but did this fix your fuel gauge inaccuracy?
i bought one of those 1 shot bottles of Redex last week, put half in with the fuel & then 2nd half before i filled up last night
- it seems to have cured it as gauge showed full after a half a mile & was giving me a 200 mile range again  :152:
it dropped a couple of bars really quickly this morning after about 7 miles but after 48 miles its saying i still have 150 miles to empty plus seem to be getting a bit better MPG 48 against the best previous of 46  :028:
i will give it another dose of Redex in a week or so just to be safe  :028:

Hi tigermike,

I discovered the following

I can get another 2 liters (maybe 3) when filling tank on Centr stand and then the fuel bars rise to almost full

The km remaining function is purely a guide and it takes the measurements from the eco fuel air demand at set intravals (ie every 3 min...) and not continuous so for instance if you are just cruising at a steady relaxed 4000 rpm 100 kph speed the fuel till empty, is optimistic and displays a HIGH reading of fuel remaining

If you are hammering at 7000 rpm, the opposite, less fuel remaining, so it is dependent on the engine demand not actual fuel in the tank...

I dont think a fuel additive would do anything to the float but glad it helped with your readings

I use motleys fuel additive made in nz with every fill. It has a lubricant in it and my cars run smoother as well
