    Hi all,

    Anyone know if it is normal for brand new fork seals to leak a bit of oil?

    A few weeks ago I changed the fork oil and installed new seals on my 2003 ER5 with 13,000km on the clock. Leak is not too bad, Just bit of a build up on the dust seal which I need to wipe away every now and again.

    All the parts looked good, no real wear on anything. I did apply some grease to the seals as per the manual.

    Might have trapped a little bit of dirt in there, you can use a business card to clean it out.

    No it's not normal.

    Are they actually leaking?

    I happen to be well versed in fork seals

    If you put some grease under the dust seal it could be leaving the residue?

    They shouldn't have anything on the fork leg really. Pull the dust seals down and make sure nothing is lodged in there letting a tiny bit through.

    You may have pinched them or split them.

    I'll lift the dust seals and have a look over the weekend.
    supa, thanks for the trick I'll give that a try too.

    Feeler gauges always work as well.

    They are thinner too.

    A little embarrassing. I lifted the dust seals today, found that I put the new seals in upside down!

    Looks like I'll be well versed in fork seals too after I redo the job.

    Old film is the best iv'e found (short of my seal doctor) but trying to find any these days is getting a bit hard. Oh and well done on spotting the problem, at least you should be a bit quicker the second time round :p

    No they're not USD forks, maybe if they were the seals would have been right way around!
    Re did them on Sunday. Yes much, much quicker, still had to take them completely apart to get oil seals out but took me about 2.5 hours this time. Haven't ridden it since though.

    I recently had to redo some forks (actually to lathe down the fork legs) and they were a right shit to pull the seals on. Ended up having to make a puller cause they weren't coming out a more traditional way.
