Carb clean...choke circuit fuel pickup tube

Choke (enrichener) fuel tubes should be probed with a stiff steel .010" or .012" wire.

You need some persistance to keep poking through the FIRST hole at about 30mm, then keep on using carb cleaner and compressed air and more poking until you've reached the whole length of the tube, which is about 60 mm.

(2nd gen, others similar)

 

is this to ensure that the choke is "choking" correctly ?

 

it worked and it did take persisitance. A guitar string at .010 worked great. Bike starts right up from dead cold. Thanks
