Hello all,
I have a '95 ST1100 that I was thrilled to purchase from the original owner. It only has 22K miles on the clock and is in great condition. It was in need of a carb sync, which I performed using a mercury manometer. (FYI, I have sync'd two other ST's I've owned in the past, so I'm not new to the process) My issue was between #2 and #4. In order to get those two synchronized I had to turn the adjusting screw down to the point of completely compressing the spring that is under the screw head. The two cylinders were pretty close at that point and I was able to sync 1 and 3 to 4. The bike runs great but I'm not satisfied with that screw being bottomed out between 2 and 4. Something else must be out of adjustment.
Note: I did remove the carbs, cleaned them, and installed new intake boots prior to the sync procedure.
Any suggestions as to what is the cause/fix? Thank you in advance.
