Fuel in the air cleaner assembly

[mrlmd1]

If it runs out of the carb that means the needle valve in the float bowl is not closing properly. Run some Berryman's or Seafoam through it periodically to keep that and the jets clean. And only use prime if the bike has been sitting for weeks and weeks, and then only for maybe 10 seconds to allow the bowl to fill up again if it was empty.
