carb jet needles

Long before I rebuilt the carb system on the 1200 I may have gotten the 1 and 3 jet needles reversed. Bike's runnin' so much better since the rebuild except it dogs down just off idle. Once she hits around 1500 rpm it's great. I haven't done the sync/drop yet. Is there a simple way to tell which needle is the no. 1 and which is the no. 3?

There is no difference between the needles when new. The reason they say to keep them in the same place is to allow for wear patterns. Just change them back and see if it helps.

What you describe sounds like something more serious though. My guess would be a vacuumproblem or the advance not working correctly. The CA models have some pretty complex vacuum hose routing.

Hi again, Esco.

The best way to test the ECU is to replace it with a known good one. And since you have other GL12s, you can easily pull one from another bike and plug it in to the questionable runner to see if it helps. There was a test in the manual, I think, but I can't find it now.
