    I'll say it again...
    tap it to the F/D drain plug size, then grind down a F/D plug shorter .
    I bet I've done it 30 times in my shop days (other peoples F up's)
    NEVER had one leak!

    My understanding is that I would need to take the FD apart in order to tap the threads. I do not have the knowledge to do that otherwise I would.

    You said the drive shaft drain plug, all you need to do is separate the drive shaft housing from the final drive. Easy to do. Once separated the drain plug is visible and no further dissassembly is needed. Look again at wireworker's post/picture.

    Only thing is that you may have to remove some material from the 10 mm boxed end of a wrench to remove the four bolts attaching the FD tot he drive shaft housing.


    For the FD (looky here) all you need to do is pop the inner cover off, that is only removing the perimeter bolts around the inner housing then using long 5x30mm bolt in two holes in the housing and tightening them to pop the housing loose.No further dissassembly to get rid of shavings.

    Hardwaregrrl, wondering what you ended up going with and how it's worked? Looks like I'm also going to be dealing with this issue... While getting my /5 gussied up for its first outing, I noticed the FD drain plug not tightening up and, sure enough, the threads are stripped.

    I took it off and ran it out to Boxwerworks, and they walked me through the drill and tap, and then insert. Pretty boring....now wishing I had sent it to Wirewrk to have a little of his DNA in my bike.:cry

    Sorry it wasn't a more exciting fix.

    i'm kind of resurrecting an old one, but I found this thread to be pretty helpful as I had to fix a stripped shaft drain too.

    I got one (actually 2 since i didn't understand how they worked) of the Dorman self-tapping oversize drain plugs. it mostly went alright, but i bent a part of the final drive (crap!). i did exactly what I was afraid of doing. the length of the oversize plug hit the FD and pushed it in. you can see it in the pictures. luckily it is not a problem any time soon. on the plus side I think it is sealing pretty good though.
    in the pics, the large plug is a 14x1.5 which i bought first because i didn't understand that the oversize was built in. I thought I had to buy a larger size plug. the little one is an oversize 12x1.75 (which is not the correct plug of 12x1.5, but i figured it would work) that I used to tap the hole (i had to keep shortening the plug) and then cut down to the correct length.
