Need help analyzing the ticking...

[ddaniels]

...noise that occurs at take-off under load. 1981 GS1000G. I can hear it until around 3500 rpm's. I would appreciate anybody local to the Dayton area meeting up some time to take it for a spin around the block to see what you think. It's not because of needing valve adjustment. Did that...twice. Put in a different clutch basket with tighter springs. From the descriptions of cam walk, I don't think that's it because the ticking can't be heard at idle. At least I can't hear it. So, if anybody local wants to have a listen, pm me or respond here. Can't do it this weekend though. Maybe next. Thanks in advance.

How many miles on it? You looked down into the spark plug holes? If so did the pistons look overly carboned up? I think Dale (Dogma) was fighting this same problem with his 1000G. And I also think I read somewhere that this has been a problem for a few people..

Less than 7000 miles on it. Yeah, the tops of the pistons are carboned up pretty good. I ran some carb/injector through the tank and I think it cleaned some out. Sure stunk bad while running during that tank of gas. Smelled really rich. I might run some more through and see what happens.

My pistons are now nice and clean (water injection method, fun!), but this pre-ignition, or whatever it is, is still present. It's temperature dependent. It's only present when the engine is warm, and if the engine gets hotter than usual can happen as high as 5000 rpm. (NC-226, and depending on throttle position.)

Ignition timing is next on my to-check list.
