Not to be a poo, but the solution for your drain plug problem (at
least in the future) is for you to buy a torque wrench, then actually
use it. Drain plug torque is typically somewhere around 12ft-lbs -
just enough to slightly squish the washer. You're probably putting
them on with twice that or more. Also, it doesn't matter that it's a
CRF, you would've ruined the threads on any brand bike.

Guys at the track laugh at me, I use a torque wrench for almost
everything on the bike...

Rowdy Mouse Racing, don't torque me off...

Head bolts only, and I couldn't pull hard enough for the final torque on a 1968
LTD. There are advantages to being a grrl.

I bet I'm the only one who has a wrench calibrated in furlong-hogsheads.

Nope, not the answer. It wasn't overtorqued. If you have one you would
understand. In the second stripped case, I used a socket connected to a
long extension so that I could thread it by hand. I think the socket was a
bit to thick walled and deflected the bolt just enough to cause a problem.
I threaded it by hand. I realize that seems unlikely but that's what
happened.

Both problems were not due to overtorque but of misalignment. It's really
difficult to get the long drain bolt aligned with the female thread boss all
the way through to the back of the right side case.

You're not a poo. Btw, this is dlevy.

I'm on board and I hear ya but.......
I have to split the cases to get to the thread in the case.

I'm thinking of trying to thread a tap through the hole to repair the
threads, or as we say in Louisiana, the treads.
