So I have a blown fork seal on a 2006 zx10. My question is why would this happen on a bike with an indicated >4500 mi. I bought the bike from someone who had purchased it from a motorsports auction. At the time I bought it I was very excited and blinded by the fact that it was a zx10 although it was given an amateur check over. Bouncing the front suspension did not cause any visable leaks. Anyways long story short less than a thousand miles into owning the bike I am leaking fork oil. What would cause this? Has anyone else had this problem? I am worried I have a slightly bent left fork though the alignment seems good.

Maybe a dumb question but do you wheelie the bike a bit? if so how hard do you come down sometimes? i have known guys in the past who did alot of travel on one wheel but weren't too good at setting it back down softly AND had their rebound set stiff as hell which caused more than 1 set of blown seals. or they could just be old?

:+1: for wheelies causing them to leak, I had a seal leak on my 08 and I rode a few wheelies, but after looking at some pics I think it started leaking soon after I bought it... maybe just a bad seal?? anyways get some new ones and no more wheelies... thats my 2cents...

Also, I have had this problem... since I bought a set of 06 forks used at one oint in time and I just threw them on the bike and left it alone...

who ever I bought them from had the compression and rebound setting adjusted to the max on the left side... made my left seal blow out :-(

I've made the front end power up a few times up and then immediatly back down. The last time ,3 days or so before I noticed it was leaking, I did come down a bit hard though striaght and slamed my junk into the tank. It was more accidental then anything else we are talking a very small wheelie like an 8:30 oclock. I haven't intentionaly tried to wheelie the bike yet if that says anything. Another thing even if it's a stupid question is why would my left seal go and my right one be fine?

Thanks appreciate the info i'm kinda worried i may have bought a bike with a slightly bent left fork I was (and still am a bit) thinking that could of caused the seal to blow. I really can't afford a new fork right now hoping a seal will take care of it.

I have a set of stock 06-07 forks freshly rebuilt for sale if you need them. I was asking about $200 so keep it in mind :)

Strapped down to much in the back of a pickup? Forks need to be able to move
I did just bring the bike from MA to FL and then back a week later in the bed of a truck. The front tire was in a wheel chock and the bike was tied down with ratcheting straps tightly as we did not want it moving around in the 1200 mi.

Just replace both seals and see what happens? and i don't think it matters how "high" you wheelie it more than it matters how hard you come down. now if the left ones breaks loose and starts leaking again after replacing them both then you have Garth as a backup but you should be fine man.

thats probably what did it, thats how mine blew, my buddy strapped it in the back of my truck for me down wayyy to tight!!!

this is why a canyon dancer is a great investment!!!! you dont have to strap the bike down so tight, it will work perfectly with the forks maybe compressed an inch or two...

the forks may have been good when you bought the bike,it only takes a tiny bit of grit too get by the outer gaurd and put a tiny cut into the main seal and it will leave a nice little channel for the oil too run out....
i allways wipe my forks with wd every ride and after every ride..i know it may not stop it but it helps in my head anyway?

a big +1 on the back of the truck blowing the seals. mine was strapped down all day, over night, all day the next day. a week later i've got fluid all over the left side caliper/fork bottom. i think a boxley wheel chock is in my future. as to why one and not both, there really is no rhyme or reason to it. one just gave up!

If a leaking seal is your only symptom, quit worrying about a bent fork. Seals can leak for the reasoned mentioned, and they can leak just because. They are a wear part, they fail. Just replace them and move on.

I make a habit of wiping off the forks pretty much every ride. If you want to use something try silicone spray, not wd40.

Biggest thing to watch out for is a tiny nick on the fork. While apart, slowly run some pantyhose up and down it and ensure it doesn't catch on something. It's a bitch to install new seals only to have a nick cut the fresh seal too.

If you plan to haul your bike much, a chock that holds the wheel (baxter and many others) is well worth the money. The pit bull is the best, but the most $$$ as well.

If it makes you feel better, I replaced mine before 3k. I just used it as an excuse to have the forks reworked with penske internals.

it would be cheaper to get your rebuilt ones than to go through the shop costs..
