Question Fork tube has a small nick. What to do??

The left fork on my old Concours started leaking fork oil really bad. Thought is was just time to replace fork seals since it had been several years since I replaced them last. On close inspection of the fork tube I found a small nick/scratch. Must of had some small metal debris laying in the road kicked up from a car hit the fork. I can run my finger nail over it and just barely catch it.
Can this be sanded down smooth and save the fork tube? I was thinking about using a wet stone used for sharping knives to work down this nick.
Looking for advice?

I suppose you can try it and see if it works. I've heard of people filling pits in fork tubes with JB Weld.

In the end you might save some messing around if you can find a good-condition fork tube on Ebay or the Concours forum and swap it out when you replace the seal.

something like that happened to my old LTD. nothing i did to fix would work. sanding, new seals, even new bushing didnt stop leak. for fix i had to buy new used fork from mc salvage yard. since then, ive used fork-seal savers on all my mc's for no more problems. g-luck and ride safe.

What are fork seal savers? The little plastic seal cleaning tool.
A good reason to run fork boots.

A respected suspension guy in the bay area told me of how he deals with these. Fill with liquid super glue, then wet sand the area down to level of the fork. I personally haven't tried it but sounds like an easy thing to try.

Sounds like it's pretty small and probably not a big deal to fix.

rather than sandpaper (if you are not skilled in sanding rond things) locate the part of the nick that sticks up (hint, the divot on the leg isn't causing the leak, more than likely, it's the small amont of upset formed when teh divot was made . . . . . and try to disappear it using a small, extremely fine sharpening stone . . . .

Wet/dry finishing paper to polish. Work up from 800 grit to 2500 grit. If the nick is too deep to polish out then clean it thoroughly with carb cleaner, and fill with a two part epoxy (liquid) and cure it under a heat lamp. Finish by polishing the repair as described above. You'll have a permanant repair.

Never used glue or epoxy. But fine wet and dry, its the sharp edges of the nick the damages the seals. I use a jewellers loop to inspect.

I successfully smoothed out a ding in a fork tube once using a fine grit sharpening stone. Had the divot been deep at all, I would have used JB Weld to fill it in.

One great way to check to make sure your fork tube is smooth is to stretch pantyhose over it and run it back and forth up and down the tube. If it snags, then it's not smooth.

I agree the real issue is raised metal. More than likely you can get it smoothed out with a strip of crocus cloth or a very fine stone like was mentioned earlier. Try to avoid flattening the area you're working on.

Use a fine stone, not sandpaper. Knock down the sharp edges of the nick and you might be OK.

Thanks guys for all of the suggestions!! I have finished sanding down the nicked area. I used a sharpening stone and some wore out 1000 grit wet or dry sand paper. Now I can just barely feel the divot ( it is about less than the size of a pin head)with no high spot. I think I will try some 2 part epoxy in the divot area. I'll let it dry over night then sand it smooth. I guess I shall see what happens.

You did all the right things and it will be fine. Ive done this a few times on my Trials bikes.
