I stripped the screw at the lower forks when changing the fork oil. The small screw that you need to remove to drain the fork oil. Any ideas on how to fix it. I would hate to be stuck buying a chrome fork lower.

 

Find out what is the diameter of this by manual or calling HD then drill and tap an new slightly larger one in the place of it.

 

Tape around the screw with some heavy tape (Gorilla,etc) so you don't scratch the leg and use a vice grip on it. The heads of those screws are big enough for the vice grip to grip. I'm sure others will chime in with other solutions, don't jump off the bridge just yet!!!

 

Stripped the screw, or stripped the hole in which the screw goes? If it's just the screw, it should be an easy fix by using an EZ-Out and protecting the lower as you're doing it.

 

I stripped the threads not the head.

 

That means possibly drilling and taping which means metal particles inside the leg which means if it was mine, remove the fork from the bike and do it right....But that's only me....

 

Just run a slightly larger self threading screw in it and forget it.

 

If it was mine, I would drill and tap to a larger size. Then, I would get a couple cans of starting fluid. Start out by spraying into the top of the tube and letting it run out your freshly redone hole. Lots of it. Oh, and NO SMOKING or other ignition sources, outside is preferable, blah, blah, blah. Don't be afraid to use a lot of ether. Then I would spray directly into the hole in the leg several times with a wand attached, wand inside and pointing up, each time letting it run back out. Then some more down from the top of the tube. Finish with a Q-Tip or two, mostly for inspection purposes.
I have been using starting fluid as a spray cleaner for years. Quick evaporation, cleans super, and pretty much will not harm any surface. Also the ultimate weapon for greasy stains in fabric/upholstery. Just keep your head working....

 

Also, if you do tap it a bigger size, try smearing some grease on the tap.
The grease will help hold the chips on the tap and keep them from getting inside the fork.
Turn the tap one turn, then take it out and clean it, re-grease and go another turn.
Keep doing that till it's done.
Don't use a spiral point tap cause they push the chips in front of it.
Use a straight flute or right handed flute tap.

 

As said.....Tap it, run a larger screw.......don't forget to install the o-ring washer on the new screw. If your concerend w/ metal shavings......run some cheaper lower weight fork oil thru to flush it out, then fill her up & roll on.........
