Just replace the plug as you banged up the threads a bit. It doesn't look like it hurt the magnet. As far as checking the chain. I would n't worry about it. You never ran it no where long enough to hurt anything. SOme teflon tape and run it in just shy of flush and your good to go.

That is the correct plug for primary drainage.
It probably rubbed against basket or chain slightly.
Does not take much to grind it.
The hole for plug is straight thru the outer primary cover so it never bottoms.
Flush is good enough.
If needed there is a white teflon paste available next to loctite at autopart store..
I like the paste better because I think it offers less chance of a long strand coming off and blocking some passage inside or wrapping up against something.

This is what I did... when I RE-drained and RE-filled the primary with NEW fluid it was to inspect the chain and what I could see of the Clutch bell... everything seemed fine. I didn't torque the bolt but ran it in until just at "snug" but the floss type tape I was using was just peeling off. That stuff is crap! I put the Teflon tape 2-3 threads above the beginning of the threads so shouldn't be any issues of lingering strips of Teflon tape anywhere. I thought maybe they had tapped it too far at the Factory but looks like others here say there is no bevel at the bottom of the tap to stop it - so... Lesson learned - won't happen again.
Thanks for the replies...
You can see my chain and Clutch in the Att'd photo (and my HD Pegboard... $50)

One thing for sure. . . the Moco made an improvement when they got away from this kind of primary drain plug to one with an o-ring.
For those concerned about the teflon tape being wrapped too far over the end of the plug and coming off inside the casing... Even if it were to do that, it is not hard enough to do any damage. There are no small orifices for the pieces to plug. It would simply be chewed up if caught in the chain and sprockets. In the off chance it got in between the clutch plates, I'd think there would have to be a serious amount of it to do anything there like causing slippage.
Like I said in an earlier post in this thread, the magnet was completely sheared off of mine. And one half of the magnet was tossed off and stuck to the inner side of the outer primary case, just inside of the clutch inspection cover. The other pieces are most likely attached in a similar manner out of sight. When I pull the cover off next time, I'm sure I'll find them!

Never use TEFLON tape
Owner's manual stipulates - NEVER use teflon tape
Other posts talk about this plug chafing.
Not clutch basket; probably chain.
Use only LIQUID thread sealer.

That plug only needs to be tightened flush with the cover. Any more and it will go right inside. The newer models do have a shoulder on them. But, that is definitely a drain plug for the outer primary. I sure you were hitting something on the clutch basket. Do do that no more, ok.
