Ok. Just as long as I'm not the only one with the problem
A bunch of folks have posted about this in the past (assuming that were talking about the same sound). Ive only had my 07 12R since May of 11 and have run across this topic on this forum and others several times. Mine makes the same pinging noise but only under hard acceleration. Interestingly enough, and I've posted about this before, I used to drive a 94 ford ranger that made a nearly identical pinging noise under hard acceleration. It almost sounds like a few quarters bouncing around in the dryer and, based on my experience, the noise is rather inconsistent with the engine speed. In other words the 'pings' do not increase or decrease with revs. I've never really heard a good explanation for what causes it. I've assumed that it may be the lifters but that wouldn't explain the fact that the noise doesn't change with engine speed. I will say that the truck did it the entire time I owned it. I sold it with about 170K on the clock of which I put about 120K on it - again, it did it the entire time I owned it and never caused any issues so I'm not too worried about the bike.
Both mine do it. Im putting together a third buell this winter, a salvage xb9sx. I'm using new cams, pushrods, lifters, pistons, a zippers oil pump and clutch hoping one of these cures the UN rhythmic clicking. When I'd brought the sx and rode it around all road rashed I noticed the clicking with every low rpm full throttle pull. After riding that bike it infected my ears and I started hearing on my 9r every now and then. I was leaning toward lifters til I got the 12scg and it didn't click till the middle of the 105° summer now it wont do it. The 9r motor still does it even with race gas when its more than 75°. Maybe the 9's just have too much compression and are prone to immaterial detonation. To the eye I can't see any face defects to the old 9sx pistons I'm replacing

I also made a post about this. I just think its the nature of our engines. It is distressing to hear though. But i have almost 20k on mine and it still runs like a champ so im not worried

Been riding XLs since the late 70s, pinging under heavy throttle means poor gas..sometimes timing on older bikes..
clatter at constant speed is just the mechanical noise, cam, lifter, pushrod, valvegear action...
worried about it in the beginning, seemed to get worse while under the influence....
like stated before , its the nature of the beast...

Wha? "These engines are air cooled?" Which engines? The Rotax in our CR is not air-cooled.
