So, long story short.

Doing a bit of maintenance on my bike, and after rotating the engine to replace intakes seals, rocker cover gaskets, and new fuel filters. The thought of doing the fuel pump no longer intimidated me.

I decided to go ahead and remove the swing arm. And when I did I found a lovely surprise.

Apparently one of the previous owners felt the need for more security of the swingarm axle. They drilled a hole right near the pinch bolt and put a larger washer that slightly covered the face of the swingarm axle.

I guess over time or from something else, it cracked.

The broken piece and pincher bolt still thread in and fit normally. But now I have this concern. I have ridden the bike for 2yrs before I just found this out (today).

Would figure, as I finally get my hands on some bigger task, this would happen. :)
