Don't touch that!! It's spring loaded and if you take those bolts out it will jump out at you and all kinds of stuff will fly all over the place....
Kidding... it's the balancer assembly, which IF you do mess with it and have had the engine apart, it MUST be re-installed with strict adherence to the service manual for proper timing with the crankshaft. It is meant to offset imbalances in the crankshaft, and getting it out of time will just mean lots of bad vibrations..... and a bunch of work you have to re-do, like removing the throttle bodies or exhaust to get at it, etc., etc. Fun you want to have on the bench rather than in the bike.
Keep yer stick on the ice....
