I changed the fork seals on my CSR 650 today, and I gotta say that it wasn't nearly as hard as I thought it would be! I put the bike up on the center stand, picked the front wheel up as far as I could, and put a block under the oil pan. Took the front wheel off, and slid the tubes out. This turned out to be much easier than my original plan of setting the whole bike on a milk crate!
As far as actually getting the seal itself out, I took a Craftsman 3/16" common screwdriver and bent the tip about 30º or so (this particular screwdriver needs to be replaced, anyway), after trimming the rubber off the inside of the seal. I hooked it under the steel part of the seal and pried the seal out lickety-split.
I guess there are two things to watch: first, when installing the new seal, don't push it too far down in the bore in the outer tube. There's a spring steel clip that holds the seal in, so just push the seal far enough in so that the clip can seat in the groove in the tube. Secondly, getting the oil level correct is a complete PITA! I think I got the level in both tubes within a quarter-inch (6 mm or so) of each other, and I hope that's good enough.
Overall, I'm glad I didn't put the job off any longer...the bike seems to hold the road a lot better than it used to. I reckon that might be because now the tubes actually hold air....
Just thought I'd put this out there for anyone considering tackling this job. As I like to say...if I can do it, ANYONE can do it!
