Hi i need a new float/sender unit for my yamaha xj900s diversion r reg any ideas where i can get one?
Don't get a new one!!! If you're anyway handy, drain the tank, slip it off the bike & turn it upside down. Scribe a mark on the body of the unit to the tank to ensure you get it lined up again rebuilding. Unscrew the 4 retaining screws holding the sender unit in place. The rubber seal can be used again but examine it first. Carefully remove the sender unit, it's crooked in parts so you need to twist it at strange angles to get it out. Once it's out you will see the float/metal rod attached to a black bakealite holder. There is a tiny star shaped washer holding it in place, very easy to lose. Prise off the washer. Keep it safe. Upon inspection of the bakealite holder(potentiometer) you will see the metal rod has elongated the hole and thus sends a wrong signal to the fuel gauge on the dash. To counter this, get yourself some plumbers tape, the very thin stuff, and wrap it round the metal bar where it goes through the potentiometer, the part that is most worn. The trick is to get the metal rod to sit evenly & square to send the correct signal to the gauge. You may have to add or deduct some tape but make sure the float/rod moves freely before you rebuild it. This sounds gimmicky but in essence it's really handy and you save £50 on a new sender unit. Before you refit the little washer, gently squeeze it between a flat pair of pliers to tighten the little gripper teeth, then refit it. Press it home with pointy nose pliers. To test it you can attach it to the multiplug on the bike and move it manually with your hand whilst watching the dash. You should have a working fuel gauge. Mines been repaired like this for 4.5 years and it's as accurate as it was before it went wonky. Hope this helps.

Fuel guage sender unit is prone to failure on this model, mine gave our at 60,000 miles.
I just use the odometer now. 200 miles per tank, so I fill up at the first opportunity after 140 miles.
