Motorcycle Repair: motorcycle carb, varnish, carbs


Question
Hey Michael, my name is Butch and I have pulled out my 1982 Suzuki GS1100EZ.  It has been sitting for about two years and I was having carb trouble when I parked it.  

Anyway, I decided to tackle the carbs myself.  I pulled them and cleaned the main jets and the bike actually started.  However, it only runs with the choke wide open.

I saw where I think the piloet jets should be, but there was black rubber over the openings.

My question to you is, first, why do you think the bike only runs with the choke wide open?  And second, are the pilot jets under the black rubber?  And if the pilot jets are under the black rubber, how do I replace it?

I will appreciate any advice.  I hope to get this baby back on the road this summer.  Thank you.

Answer
Butch,
 Not familiar with this type of bike however, the bike should only run sufficiently and breifly when started from cold with the choke closed.  Other then that you should have the choke fully open after it warms up (15 seconds or so).  Pilot jets, if there are any in that model, only function at idle and up to 1/8 throttle.  They provide the fuel needed to sustain idle w/o all the air rushing through the barrel creating the venturi action at the main jet.  You may need to clean the carbs w/ compressed air and solvent if fuel was left inside to evaporate and leave varnish.  NEVER use picks or wire to clean out jets.

Hope this helps,
Mike
