Can anyone clarify what the white plastic tube is for ?? i dont see the point unless your running under water.

Often wondered the same thing Lou.
To try and figure out what it's for my 1st question would be do the Hall effect bean cans have it or is it just fitted to the points bikes.
Doubt it's a snorkel for running submerged.
Ok I just checked and it was fitted to 09/80 so points only.
I reckon it could be a vent to prevent the build up of ozone in the bean can.
