This video made me go for it on mine. Always been scared. I have a question though. My forks are the same when i took them apart as the ones you are working on in the video, but i have been reading about changing the lower and upper fluid. The way you do it in this video, does that accomplish both? And is there a certain way you are supposed to "bleed" the system other than just pumping the air out like you demonstrate when you put the new fluid in? Thank you

@mxkx48 - If you have cartrige forks like in this video, you only have one chamber for oil; however, some are difficult to get all the oil out. if you can't pump the rod to get it out, take the large allen head nut out of the bottom (compresion stack). That makes it easy to drain.

How many miles were on the forks? Was the oil covered in metal dust?

@Bulgdoom - I don't know the miles or hours, but it had been a while.  No noticable "metal dust", just dirty.

What is the purpose of that plastic piece around the dampening rod? While I was changing my fork seals, it was broken.

@blazinhott112 - it is a spring guide. It keeps the fork spring straight when compressing. I suggest you get a new one.

Yeah I figured it out. Luckily Yamaha sells that specific part.

@TheTacokid09 - your 2002 will need a 46mm. Just go to our site and key in your model and it will pull the right one up!
