Another Fork Seal thread

I've read a couple of threads about seal issues on the 450X and I'm definately having issues. I bought a new 09 about 5 months ago and am needing to put in my 3rd set of OEM seals:banghead: I've read about the alignment issue so have taken care to tighten down the left pinch bolts and then compress the fork a few times with the brake on before tightening the right side but have a new leak again. I worked on the fork about a month ago and replaced the bushings even though everybody says the bushings should be fine. They definately look fine but here is the issue I noticed. I was checking to see if bike was stable after strapping it into truck and I noticed that it seemed like I could easily move the bars quite a ways without the wheel moving. I duplicated this with the bike on the ground by putting the tire against the wall while sitting on bike and also by just holding wheel between my legs. I checked a brand new bike at the dealer and seemed equally flexy. With the fork leg off the bike we could hold the upper on the table and move the lower slightly. Changing the bushings didn't help:banghead: The lower bushing on one side seemed to go into the upper tube very easily too. Anyway just wondered if anybody else noticed this? Seem normal? Any suggestions??

Could be the inner bushings worn out but I can't say for sure. I would put them in a gun case and ship them to Precision Concepts where the problem will be fixed right the first time saving you time and money. Bob Bell's work on my 450R forks is nothing short of miraculous! http://www.precisionconceptsracing.com/

This is normal. Just some twisting of the fork tubes and clamps together.

It would have no effect on seals.

Have you inspected your tubes closely?

I do keep a pretty close eye on the lowers after I noticed that even the crappy hard water we have here in AZ likes to leave water spots on the tubes so I dry them after each wash. I also noticed that this latest leak after replacing the bushings inlcudes some discoloring of the lowers behind the plastic shields. I will be looking at it closer this weekend and hoping it's not damaged. The flex in the front end still bothers me, we have a couple other bikes that are about 5 years old and ridden hard and dont have nearly as much flex, a Yamaha and Sukuki.

I'm in AZ too and have been saying for years the water spots on the slides eat seals so you're not crazy. That's a good observation. The flex you describe is not normal. Do yourself a favor and get a suspension specialist to go over your forks. I would recommend Precision Concepts or Johnny Wiseman who is in the PHX area and is Destry Abbott's mechanic. :thumbsup: Seriously you'll have forks that'll work so good they'll blow you away:ride:
