Celebrating 100,000 kilometers! With a digital meter, it doesn’t roll back to zero, does it?

It’s wearing down nicely.

We’ll replace it with the later-model damper.

Starter motor O-ring replacement as well. It doesn’t appear to be leaking yet.

Generator damper replacement too. It had gotten a bit stiff.
We’re out of stock at the shop, so we’re waiting for it to arrive.

We’ll polish what we can. This is one of those rare opportunities, so let’s make it as clean as possible.

IN #1

EX #1 Slight scuffing

EX #2

IN #2 Some scuffing.

IN #3

EX #3

IN #4 Slight scuffing

EX #4
With this many kilometers on it, it must have been treated well. There’s almost no scuffing at all. Rocker arm design tends to scuff easily, but I’ve learned that it really depends on how you use it.
The valve clearances were spot-on except for two spots (and even those were just slightly off).

There is some sludge buildup in the oil, which is a bit dirty. Given the mileage, it’s probably just accumulated over time. The cam chain tension looked good.

Before doing the valves, we’ll assemble with the bolts we prepped and finish the head cover.

The oil level sight window is so dirty you can’t see through it, so they want it replaced.

It’s press-fit with liquid gasket.

If you pry up the liquid gasket a bit and warm it, you can sometimes get it out by hand. This is pretty gross…

It’s a standard part, but we’ll go with genuine OEM for peace of mind. GSXR has a specific part number for it.

Once we clean the cover side, we’re ready to install. We’ll apply a thin layer of liquid gasket to the edge.

Let’s roughen up the cover side overall. A gentle press-fit is the smart way to go.


This is something I made before, but when press-fitting parts, it’s best to avoid using a box if possible and instead make a “press-fit collar with good dimensions that centers easily and goes in smoothly.” It makes future work easier, and even after doing it 100 or 1,000 times, you’ll have fewer mistakes.
Unless it’s something extreme, you don’t need to tap seals at all—just push with your hand and it’s done with a “pop!”

Then apply liquid gasket to the edge and let it dry, and we’re done.

It’s clean now and I’m happy about it.

The oil’s dirty, so we’ll change it.
We’re waiting on the generator damper. Also, I’ll make that wire bracket thing for you.
