Nah, that would throw off the calibration of my torque wrench :wink:
I'll just use a Johnson bar, instead.
If it were my bike, I wouldn't fuck with oversized plugs. Remove the pan (or have somebody remove it for you) and have a machine shop install a heli-coil. Either that, or replace the pan.
I don't want any of those filings in my motor trying to butcher the oil pan to fix it.
Removing the pan is easy enough, but you might want some assistance when re-assembling. If you have some help, you'll be back on the road tomorrow afternoon.
+1 on this Nik. An oversize bolt would just be a temporary fix if it works at all. Most likely it'll just finish of what ever threads are left.
There use to be rubber replacement plugs for cars, don't know if they still make them. They looked like a bottle nipple. You press them in with a rod and when you pull the rod out the rubber springs back to seal the hole.
Even if you can find one of these you should still pull the pan for a proper repair.
