Hi all,

Im having an issue figuring out what the standard jetting is on 81 GS550T.

Clymer manual that i have on hand does not have a list of jets used, and i can't seem to find the
list in the OEM manual either (looking at pdf file). The bike appears to be stock and im not changing anything,
just trying to troubleshoot bad spark plugs (all 4 are different in color/buildup). Pulled the carbs and i can
see that someone has definitely been in there, with screwdriver marks on the jets. Not sure if the jets have been
swapped at some point.

Where can i find the standard jetting specs for BS32SS carbs on gs550?
 
Answering my own question since i managed to miss the manual spec on this model somehow.

-- Specs from the manual:

Carb: BS32SS
Main jet: 92.5
Main air jet: 1.6
Jet needle: 4BEL2
Needle jet: X-6
Pilot jet: 40
Float height: 22.4 +- 1
Idle r/min: 1100 / +- 100
Spark plug: NKG B8ES, gap 0.6-0.8mm
