Surprise! Splines dry and worn
I guess I shouldn't have been surprised when I pulled the final drive unit and found the splines and coupler dry and worn. The shaft splines are worn about half way through but the coupler looks like it could've given up at any moment. I've ordered a new coupler, I'll pack it with grease and ride the bike. I wonder why the coupler/ shaft unit wasn't made wet? If it ran in a bath of gear lube it would probably last forever. I'll partially blame this on the dealer. The previous owner was very good about having the bike serviced and the dealer replaced the tires. The dry spline problem is well known, seems the dealer would've greased it while the rear wheel was off.
