D Jet kit GS550

[headsbikesmopars]

Installed the Dyna Jet kit in my 1980 GS550E as per instructions. It starts good but will not idle on its own without help. It is GREAT 3000 and up but pig rich on the idle circuit. The jet kit had restrictors that glue inside of the air bleeds on the bell . It has pods with V&H 4 into one exhaust. Fuel screws are 1 1/4 turns out and stock pilot jets, so the only way to lean out the idle circuit is to remove the restrictors in the bell or go to smaller pilot and adjust fuel screws . Floats are all in spec. Carbs have been synced. It starts great but sputters badly untill almost half throttle and runs great after that. I think the main and needle are really close but the idle circuit is the problem. I am Thinking of going back to the stock set up on the idle circuit. I think the needle is really all it needed but went ahead and installed the whole kit believing the kit is designed to calibrate better as a unit and not in part. Thanks for an insight,..

Those restrictors only affect the needle and main jet circuits.
You can lean the idle circuit with the idle mixture screws and going down on the pilot jets.

Thanks Chef,..
The screws are out 1 1/4 turns . not much room for adjustment there, but Will give that a try , Thanks.
