I have zero idea of what to listen for, aside from reading on the internets that I should listen good for the first 15 seconds, shut it down, squirt a bit of fresh oil in each cylinder, and wait for the sound to come back. As far as I can tell it's not a problem, but I have a weird sounding click at high engine speeds, it's probably just the valves and rockers making usual noises. Of course I'm sure this is normal, and like I said my ear is sub-amateur.

Have any of you had experience with a slap-happy 850?
 
Firstly I think squirting oil into the cylinders is only for determining possible problems with rings when getting low compresion readings while performing compression tests. Never heard of using the technique for "piston slap" problems. That being said I have had recent experience with piston slap on a Laverda SF1 750 that was way out of spec (gotta love buying bikes long distance on Craigslist).

You will notice engine noise while accelerating at low speed and also cruising at medium speeds where it will come and go. Can get pretty "clanky" depending on actuall clearance. I would first make sure that your ignition timming is spot on and run some premium gas if timming looks good. Make sure you have the right plugs> heatrange.
