Water proof extreme pressure chassis grease.


One last question and I think I should be set, I use the the whole 06 front end yes? Just want to make sure I don't need swap out different parts such as the 04 steering stem or something. :thumbsup:

Hopefully my next post will be good news and a picture or 2.

Well. let's see...

If you get the whole front end with clamps, they bolt right on.


The stems are the same, the bearings are the same, the wheels, spacers, and axles are the same. The whole deal is a 100% bolt on if you use them as a complete set.

Ebay. Only like $230 shipped but that was b/c there was some cosmetic damage to the bottom of one of the forks and the guy didn't clean them before pictures so it wasn't all "shiny". But it included everything, forks, trees, bars, extra new grips, levers, cables, brake caliper, fork guards. Most of what I saw was closer to the $400 range though.

UPDATE:

Got the parts swapped over and went to the track for a test run. Moved the forks up to the first line as I remember reading it makes for a better handeling bike that way. Much different feel, front end turns a lot quicker/easier. Almost too quick from what i'm used to, probably just have to get used to it though. Went big by the end of the day on some long/high doubles and bike felt plush.

As I thought though both seem to be seeping oil even though the seller assured me they were "perfect". I may just take them in to be revalved while I'm at it.

Question...I was playing with the clickers as they were both different and how do I go about finding the middle so I know both are set evenly?

Run the clickers all the way in until they stop, then back them out until they stop, counting as you go. That will tell you what the range is (should be about 22-23 on the compression, and 21 on the rebound.

Also note that the adjuster positions are reversed from your old fork; compression is on the top, and rebound on the bottom.

Being as I know nothing of susp settings and you have an 06 can you give me a decent starting point that I could try for the clickers until I get it revalved? I race GPs and desert in the open C class, 6'2 210lbs.

Standard original settings for the '06 were 11 clicks out from all the way in on compression and 7 out on the rebound. From there, follow this general guide:

The fork is more than night and day different, and a huge improvement. The '04 shock is pretty good, though. The '06 has a beefier shaft, and several other little updates, but there's not so much that I'd look for one instead of having the '04 re-worked.


I took a look and I believe that the rear shock is also set up for a 50lb less than myself guy. Instead of spending $100+ and a new spring and then going to get it all revalved I was thinking about swaping to a newer shock as well. Seems like it would be more cost effective and slightly better than the 04 like you said. What years swap over, and is it a direct swap or?

Thanks again, I printed that out and will try messing with it at the track this weekend at my bachelor party to see how it works. I'll be taking the forks in for a revalve though in a few weeks.

'01 to '09 will bolt up, but the '08 is slightly longer, and the '09 is valved for a different linkage ratio.
