Hello. I've been having a few issues since getting my scoot back from the painters, namely, some bead was left in the tank! So 2 things
1: I've cleaned the fuel pipe, carb filters, and petrol tap. When I am approaching high revs whilst going along, the bike seems to be running out of fuel, if I pull the clutch in and rev the engine, it clears but then comes back again. Is this still a particle issue or something else?
2: Is there an easy way of putting the fuel tap onto the tank? I'm struggling to maneuver it around my new silent block and trying to get a good seal? (I'm aware of the opposing threads !)
Cheers

The first issue might be a blocked air-bleed in the handle of the filler cap. If your tank isn't too full, try running the scooter with the cap off, and see if the problem goes away. If it does, try to unblock the air vent (fiddley).

The fuel tap is also fiddley. With two opposing threads, there is a certain sweet-spot where both threads catch. If you are really keen, try taking the tank out, fitting the tap and re-fitting the tank, but first you might like to try loosening the tank straps and rotating the tank to give a bit more clearance around the engine mounts.

Good luck.

Many thanks

Ok. New fast flow fuel tap on. My problem is still there! Poodling along and then the engine will start to splutter like it is running out of fuel and start to slow down, pull the clutch in and rev, and the problem goes. Does this sound like blockage issue still?

Have you looked into this yet?

Yes. Bought a new Casa one

You got a partial vapour lock or an air bubble in the line? Can be persistently annoying like you described and you should be able to clear it by flicking the fuel pipe to dislodge the bubble, with this warmish weather at the moment, its prime time for such.

Oh ok. I must say that I have seen an air bubble in the line but put it down to the inconsistency of a carburettor fuel supply. Thanks
