350X stripped valve cover thread.

[ScreaminRed]

Hello all,
I was thinking of running a bottom tap through it to see if that would clean
up the threads. If that doesn't work, what's the next best thing? Heli-coil or should
I go to the next mm size up? The bolt itself is fine. It had some goop on it to hold it in place.
Any ideas will be appreciated.
Thanks!

That is how I'd go about it.

Invest in a good helicoil, or permacoil set, if the threads are stripped its pretty unlikely that a tap will clean them up, and if ya get some threads, it will be loose and the bolt will loosen up and fall out, before I got a collection of inserts the bike shop down the road from me charged $10 bucks to fix a hole..
