I get some wobble going around high speed corners.

Others have said check your spokes and run correct tire pressure. Good advice. Next I would question your suspension. I am going to guess your fork seals are not leaking because that would be an obvious cause. Are your rear shocks set too low? Set your shocks to the firmest setting and go attack those high speed corners and see if it makes a difference.

I've heard it used to describe the riders legs slapping the outsides of the tank, gasoline slapping the insides of the tank (not limited only to motorcycles) caused by violent side to side motion. Never heard the handlebars before (I think something would have to break or bend before this could really happen on most street bikes). Anyway it sounds like a real bad thing :'(

Knees make a lot more sense. The handlebars seemed like some darned violent jerking around to me too; I just didn't visualize anything else in the vicinity of the tank.

Yeah, good one Bobo.
My longest recall of the term is the verb "tank slapper".
It occured when racing motocross and getting the wheels off the ground (mostly in the whoops) and landing awkwardly causing you to rise from the seat and have your knees bang both sides of the tank in a furious motion, generally spitting you off your bike. It was quite funny when you saw it happen.

Man that was back in the 80s. Hurt like hell too, especially on those rigid Honda ATCs and Yamaha Tri-Motos we had.

I remember getting a nasty headshake on my old Suzuki GN 400. Got a new leftover '81 for $999. in '82. In really hard corners above 40 mph the handlebars would suddenly wobble badly until either I slowed down or the road straightened out. First time it happened I nearly crashed in a corner going about 60. My S40 doesn't seem to do that but I haven't really pushed it to the limits. (yet) Shocked

from what i understand it is a very advanced riding technique, that under NO circumstance should be attempted on a savage. the technique is best suited for sportbikes and the squids that pilot them. it is used mostly to reduce the gene pool.

I thought that it might involve a sudden stop or a wash board dirt road.
