Wingwider,
The $334 for labor isn't that far out. Anything on a Wing takes longer, because you have to take so much plastic off to get to anything. R&R the forks is probably flat rated at 2 hours, and rebuild the forks (right) is probably around 1.5 hours, so 3.5 to 4.0 for the job isn't out of the realm of reality. Times the shop labor rate ($80-$90 / hour?) and there you are. Maybe plus some consumable supplies, shop rags, solvent, and so on.
Yes, it is pretty easy to do. Just takes patience and a little knowledge. A service manual is a big help, and so is Fred Harmon's video set. He shows you how.
If you want to do it yourself, you should have a manual, a torque wrench, and a way to drive the seals. It also helps to have access to an air zip gun, to loosen the bolts that hold the cartridge and damper rod in. And you need a long hex key socket to get to them. People take a hex key & cut it off straight, then put it in a socket. You also need a GOOD long 4 MM (I think) key to remove the anti-dive valve. The little bolts are easy to bolix up. Do one fork, then the other. Then you won't get parts confused.
We clean the tubes out with non-chlorinated brake cleaner, but any solvent will work OK.
If you're OK with taking the forks on & off, you could take them to somebody to rebuild for you. Half the labor is just getting them off & back on. Worse if you have a bunch of aftermarket stuff, like the Kury rotor covers & ring of fire. The connectors for the ROF fail as soon as you touch them.
There are some other things you might want to consider once you have the forks off & apart. Better springs, GoldValves, Traxxion AK-20s, replacing your stem bearings with roller bearings are a few things that come to mind.
If the fork seal is leaking, check to be sure nothing got on the brake pads. Oil on brake pads is kind of not good.. :22yikes:
If you want to discuss this more, PM me with a phone number & I'll call you, or you can call me. I'm at my real job right now, but could call you later. Or, we will be at Motorcycle Nightin Lowell tonight, if you live north shore-ish and would like to come.
http://motorcyclenight.com/ It runs from about 6-ish to dark-ish. You see lots of interesting bikes, mostly sport, but a lot of other types too. The weather looks nice tonight, good evening for a ride.
