Hello all!
Currently riding a 1989 sportster. Stock pipes, moon air cleaner. Bike was running a bit shit, and it had one of those dynojet kits fitted, so i decided to change back to stock. Stock needle, stock spring,stock emulsion tube, 45 slow and 165 main, and changed the plastic fuel inlet for a brass one. Now the bike will barely run.
I have noticed that when i have the bike is running at idle, if i have the air cleaner off, i can see fuel spraying out from the needle jet. Which then just sits behind the butterfly until the throttle is opened, then the bike dies or has a major backfire through the carb. Im guessing this isnt right!
I have made sure the needle jet is in the right way, with the chamfered edge going into the venturi. Although i have noticed that the emulsion tube doesn't screw all the way in, as there are still threads exposed. Is this right?
Has anyone got any idea whats wrong!?
Any help will be much appreciated, as it sucks finally having some nice weather here in the U.K, and no bike to ride!
Cheers
