I just rolled past 11,000 miles so the forks were due anyway.






Now I really need to get these taken care of.

I'm ready to buy all the Fork parts Al has listed at American Sport Bike and I've been reading posts about Forks for about an Hour but haven't found any good posts on the seals themselves. I have a service manual and quickly glanced through it but though I thought I'd hit up Badweb for some help before I tackle this one.

Any input on changing the fork oil and all the seals???

Buy a seal installer. I did about 4 sets without one, I actually use PVC pipe but the Tool works much better.

Follow the directions closely.

Make sure the fork oil level is right and equal in both forks.

Dont forget to use electricall tape on the fork tube ends when sliding the new seals over those tubes,they can cut the new seals, then you get to replace them again ! !also you need to bleed the air out when you out new fork oil in to get the air bubbles out, Ok I havent changed fork seals on my buell, but I have done it many time on my dirt bikes throughout the years. I can only assume these same rules apply ! !

Ok, clarification needed.

My forks are leaking, thats obvious. To replace the seals and STOP THE LEAK do I need to remove the damper rod assym. and basically tear down the forks all together or can I just follow the fork oil change procedures and replace the oil seal while I'm at it??

No need to remove the damper rod just to replace the seals.

Just what I needed to hear Al.
I'll be placing an order at American Sport Bike later on today. Thanks.

Have you tried cleaning under the seals? Many times the seal is ok, just has dirt or grit under it. Just slide an old piece of film or a thin feeler guage around under the seal to remove the dirt. Might save you a lot of work.
Not that it can't happen, but fork seals shouldn't fail at 11,000 miles.

I havent tried cleaning under the seal. If I wasnt due for a fork oil change anyway I would look to avoid opening them up. Thanks for the tip though, I'll keep it in mind if they leak later on down the road!

One thing I did was to have a heat gun just to heat up the tubes ever so slightly...I don't know if it was the right thing to do, but it SURE made the things come out and go in much easier...I changed mine using PVC cut in half and held on with hose clamps. IT worked great. I had never done it before and I found it VERY EASY jjust take your time and keep everything organized and clean.
