1986 Gsxr 750 Running Rich at Idle
Hello Looking for some direction on my GSXR 750 running WAY rich on idle... Black smoke everywhere....
Compression is 140 equal across each cylinder,
Check value clearances adjust all good
Checked cam timing ... it is correct.
The bike has a set of California carbs on it. (The pilot air mixture screw is plugged with a brass insert) I removed the inserts
The carbs have a plastic insert for the emulsion tube / Slide Guide, I have removed and replaced the two o-rings on the plastic tube.
The carbs are mint clean, slides, needles, jets all clean. but the bike is still running rich?
Question, I have worked on California Suzuki GS 1100/1000 in the past and the pilot jet passage is always plugged with a black rubber plug.
My carbs do NOT have a set of plugs in the pilot jet... are the plugs missing? Will this solve my rich running issue?
