The US totally got the boring name scheme.
Japanese cars used to be named after flowers.  I think the numbers appeal to a wider demographic than teenage girls.  ;D

Motul is a premium fork oil.  The seals will be happier with it as well you should have less "stiction" as people call it.

The job is done - it was easy with Scotty's written help!  The only thing I would add is a modifier to my modifier - I still ended up chewing up my clutch cable housing a little bit...  even the electric tape I wrapped around the allen wrench got mucked up, as you'll see in the photo.  The two cables that come through the left side opening of the nacelle really impinge on the space the tool needs to turn.

I finally sussed it during reassembly.  I tied the clutch cable forward, toward the headlight - that separated the two cables for a little more clearance.  I threw all the protective rags away, and replaced them with a roughly 1"x3" piece of aluminum flashing with some tape on the bottom to protect the nacelle's paint, and bent into a U around the opening.  Problem really solved - I can see what I'm doing, and the cables are well protected:



As for the job?  Keep in mind that this is, for all intents and purposes, my first bike, and I've only been riding a year... if I hold the front brake and push the front end down, I think it's smoother than before, but honestly, I really don't notice a difference while riding.  Same thing with my Hagon rear shock replacement - it looks better, but it doesn't feel any different.  Like I said before, it's a good experience, and hopefully I've improved the bike's handling ability for safety's sake, but it feels like the same ride to me. 

I was more careful about collecting the old oil from the second fork; I managed to grab almost 190ml from it - maybe simply having near the right quantity of oil was enough.  If so, I can't imagine what bad shocks must be like...

The righ quantity is most important.  It creates an air space of known size that acts as a progressive spring.  Too little oil = too much air = too soft a spring, and it tends to bottom on hard stops and wallow in corners.  Better quality oil of a good viscosity matters too and will last longer and perform better but quantity is key.

Job well done!

Then again, the manuals I love the most are the ones I have with all the greased up, dog eared pages.  Still something to be said for paper.

Scottie: Yeah, even though I build my own I still don't have complete faith in any computer, regardless of format. Fantastic job on the tutorial, and many thanks in advance for when I do it!

mattsz: Beautiful job putting that tutorial into a .pdf!! I now have it on portable drive, and printed/added to my manuals, so I'm covered. And good thinking re the aluminum shield for the job! Thanks!

 :( Before I read this excellent article on fork removal I had my bike in for some other minor maintenance. Mentioned that I was thinking of changing the fork oil. The helpful mechanic at the shop assured me it was easy and he would do it for me as the front wheel was going to be removed. he then proceeded to try and removed the drain plug at the bottom of the forks. He found they  were really tight so he gave the left side bolt a good wack with a hammer to loosen it. Can now hear what appears to be something inside the forks turning as the bottom bolt is turned. I'm a bit pissed off and concerned that  he broke something inside the forks. Any one have any knowledge as to whether he might have broken something inside. No leaks showing and it still seems to be working fine but I'm concerned anyway. never did get the forks off and the oil changed.

Snug it up with a cordless impact driver.  I had the same thing when I changed my fork oil and a couple of bumps with the impact driver did the trick.  I read the recommendation somewhere else on this forum.

Sorry for dusting this one off, but I just wanted to get a bit of clarity here before I dive in on my project-  What was the final verdict on the oil amount per leg - 180ml, 190ml or 195ml? 

I plan on using Bel-Ray 10W Fork Oil, so I suspect viscosity has no bearing on volume.

Bike is a 2014 C5, so I'll see if there is any "upgrades" once I tear into it.

This is an amazing tutorial by the way - great work Scott!

I used 195 and never had any issues, and the fork felt good.  195 is 5ml down from 200.  I heard/read that at 200ml some people were blowing seals.
