CB550K3 with PD carbs

(1/2) > >>

Johnny4428:
Without boring everybody with the PD woes, I fired up the 550 today after about 6 months in winter storage and I have never had this bike so keen to start in the 35 years I have had it. Especially coming out of winter storage. I had to remove the carbs after I discovered the tank filter had a hole in it. So decided to order as I should have done earlier new pilots, instead of ordering 42’s I ordered 45’s. Also I refurbished the coils with new leads (as per the Ash blurb). But I will reserve further bragging rights in anticipation of a proper road test. Happy days! 😄

(had to close choke to keep running too after about 20 seconds running)

Bryanj:
Sounds like a good idea, they were designed to be "lean burn" for the US market so probably a good mod.
Where did you get the pilots from?

Johnny4428:
Sirius Consolidated Bryan. Just wondering now if I have to adjust the mixture screw any from standard setting.

Bryanj:
Possibly but they have a very fine adjustment as the pin is tiny DO NOT screw them in very tight or you will damage the pin and seat.
I take it you know there is a spring, tiny washer and O ring on each screw

deltarider:
Here is how it looks.
