Hey, ID of tube is ~22mm, so cork float outer diameter is ~21mm wet (will swell up), & about 20mm long.
I've inserted a thin/stiff copper wire strand through the very bottom of the tube to stop the float dropping out, as it doesn't reach the bottom of the tank.
I'd like to use something non-porous, such as a glass ball (light bulb will fit) or a small metal float, might be able to solder something up.
I'm on my second tank now after float added & will see how it goes. I was a bit nervous about running it down to Empty, as the float sits higher than the natural fuel level is, so last 20km I was waiting for stall.
After hitting 100% empty on the gauge and range, I added an extra 5kms before refuelling - bike took >16 Liters, so still >2L usable left.
My theory is that the float/cork will provide a stronger reflection back up the tube to the receiver, giving a more accurate level on the gauge.
When I bought the bike 6 days ago, the gauge showed 1/2 tank but it quickly dropped to empty with the fuel light on while riding home. It only took 13 liters to fill at that time, so it still had 1/4 tank in it.
I'll have a better idea once I get a few more k's into it.
