Fork Oil Replacement
 

If you ever needed any persuading to change the fork oil in the stock shocks regularly, this photo should help. That gunk...!!! Taking it out today to see how it handles.

Also, I discovered someone had put progressive springs in my bike. Don't know what make or spring rate but win win! :D

You'll need to put fresh oil in as well as taking the old oil out ;), Measure the air gap, rather than relying on volume when re-filling.

The stock springs are progressive, can't quite tell from the photo but I think those may well be standard :)

They are? All the photos in the haynes manual showed linear springs with a huge spacer, but maybe I'm going mad and had a silly moment! Either way, they seemed to be doing ok for my weight for the time being, and hopefully fresh oil will help a bit more. My rear shock is kaput mind you, but that's on the list of things to sort. :)

I did indeed, old oil out, new oil in (Bottle on the left is what's left of my fresh oil! ;) ). Measured the air gap according to the manual (94mm from the top fully compressed with no springs in).

On a different note, I'm going to have to drill out my front mudguard bolts as some muppet overtightened them so much the allen bolts rounded off instantly... :mad: Meant I had to do my forks attached to each other. Fun times were had!

Edit: Having re-read my original post, that is the most unclear thing I've written in ages...! Doh...

It was this photo that confused me then, as my spacer is tiny compared to that one! Threw me off completely!

Stock for the curvy are linear springs 0.7 rings a bell.

The items in your original post look very much like the standard ones I took out of my k4.

Fair enough. Just that photo confusing me mightily! Still, took the bike out for a ride and the front feels pretty good. Rear is still shot, and I've still a 'lurching' problem when holding steady throttle at 20/30mph or so. Those two are next on the try to-fix-list! :)

EDIT: Wonder why the spacer in the Haynes manual is so massive. Different bike/fork? Would be odd wouldn't it?

Re: Fork Oil Replacement
 

standard spacers on the pointy are 45mm.

Yeah, just wondering about the manual though. Ah well. It's not particularly important. Just piqued my interest! The stock springs with 10w oil seem to be working pretty well for my weight so far. Cable tie shows I'm using almost all available travel under very heavy braking so pretty pleased! :)
