I’ve been seeing wheel bearings that are surprisingly tight lately. Some don’t even turn by hand, which is rare, but it’s amazing how they don’t break. I think about it every time. This time it was just an adjustment.


The caliper looks fine. With single-piston calipers, try to remove the boots and clean them as much as you can.
Water accumulates, the pins rust, and the operation becomes poor.

Inverted forks need inspection when removed. They’re in pretty rough shape.

I cleaned it right up. Modern chemicals are convenient.

The grease around the levers has changed to something different.
Smooth input and return are ideal for the control system.

The throttle was clean.

The shift side is direct, so only the brake. Disassembling it occasionally really helps.

Poor sidestand operation puts you in a bad mood from the start. Smooth operation is best.

For some reason, the breather hose had come off. I wonder why.

The air cleaner might be worth replacing next time.

There’s no synchronization, so I changed the coolant and replaced the cap with an NTK one.

I thought the lamp was burned out, but it’s fine.

I was shocked by all the multi-taps. It was a grounding issue. That needs to be fixed soon.
All done.
