just a quick q... ive noticed some air bubbles in my oil pipe so im going to bleed it when i fit my new 70 kit, but if the pipe going from the oil pump to the carb is empty, how do you bleed that pipe?
Ensure top of the Oil Tank is open to atmosphere, undo the carb oil feed pipe (smaller bore pipe after the pump) and run the bike on a separate fuel line of 50:1 premix ensuring the oil inlet on the carb is sealed first. You will see the oil fill and once the pipe is full reattach to the carb. Kill the engine, swap the fuel lines over and away you go with no recurring air bubbles.
Yup, just place the can higher than the carb, draw the fuel through and attach to the carb (siphon method). Saves filling your petrol tank with premix and then draining etc.
just undo the bleed screw on the oil pump until all air is released then run it up on sperate fuel until its reached from the pump to the carb
