My brother helped remove a seized axle pinch bolt yesterday & I could tell when I picked up the forks they probably had been caned, so I was expecting the worse when I had a squiz inside.

I tore the the left leg down this arvo. I had never seen inside a cc fork before. Mmm-kay, here goes..

Free piston's shagged - o-ring & spacer split. The oil & dust seals and the circlip were rooted, too. Slider chrome a-ok, all other internals look good ats, including bushings. Pretty happy with that. I measured the spring, too - the stock (AUS delivered) spring rate was 0.459 so very close to what I have now in the Sachs @ 0.46.

Question - is there a difference between an oem placcy free piston & after market one (I would do the drill mod to a new oem one if i went that way)?

Note gate latch rod holder - works a treat!
On a side note, How do you measure the spring? Not sure what is in mine that's all
