[QUOTE="Fred W, post: 1349212, member: 3828"] Well, nobody rose to my trolled question about why the rear wheel spins when on the center stand and the bike is in neutral. Maybe because of the whiny shit that happened right after it? So I'll jump in and answer my own question so that the next time someone searches on this, maybe they'll get the answer. When the bike is in neutral on the center stand the clutch is fully engaged (unless you are pulling in the lever) so the input side of the transmission is directly connected to the running engine. The bike is in neutral which slides the input and output halves of the transmission to a state where the gears are disengaged with each other, but... the gears are immersed in the engine's oil, so the relatively quickly spinning gear shaft on the input side churns up the oil that is in the transmission, which creates a very loose fluid coupling to the adjacent stationary output gear shaft, which is directly connected through the drive shaft to the rear wheel. If the oil were less viscous it may not couple as well (mentioned earlier), Warm oil is always less vicious, so you may not see the phenomenon on a warm engine. If there were some slight mechanical drag on the rear wheel, it may not spin even with the same amount of fluid coupling. (also previously mention) In the grand scheme of things, this is a byproduct of the design, and not really intentional, so whether the wheel spins or not is not particularly important, but it could be an indicator of some other situation which could be important (like binding brakes, etc.). That should be clear as mud. [/QUOTE]
