IS ignition timing adjustable on '83 1100e???

[browe58]

took it for spin to get it warmed up & rechecked w/ timing light. owner's manual says to check below 1500 rpm and above 2350. amazingly, w/ plate turned clockwise to the end, it's RIGHT ON on both timing marks and the knocking at cold start is gone. timing went from one extreme (fully advanced on the plate) to fully retarded and other than the cold start knock no longer present, there is no noticeable change in performance. befere & after, it started easy w/ immediate throttle response and pulled strong in all gears / rpm without skipping a beat. now i have to observe if my mileage improves. overall, i'm very pleased. thanks for everyone's help. peace.

i just got back from a "spirited" ride and i can now defintely notice the differnce, especailly above 60 mph. needless to say, i have a huge grin on my face.

Does your signal generator plate look like this? if yes, note 3 screws holding timing plate on- loosen them and you get some movement, but not much. review rapidray's advice. Remember to mark where you are now, in case you decide to backtrack.

Ok, I have run every wording for ignition timing procedure I can think of in the english language. I can't come up with anything... What is "rapidray's advice"??? Please point me to the right spot/thread for proper timing procedure...

That would be because it was not designed to be adjustable. All rapidray mentioned was that there was a little play in the slots so it could be adjusted by taking advantage of this play. The timing numbers are listed in your Service Manual. You could possibly dremel wider slots in the timing plate, but I doubt its effectiveness.
