Changing spark plugs on my bike. Screwing in the the new one. Long story short I overcranked it and stripped the plug. The screw part is stuck inside my cylinder, with the rest of it in my hand.  [bang]

Any way to get this out?

Wilco, don't understand.  You mean you stripped the threads on the head and broke the plug off?   Where did the plug break?  

Or do you mean the thread metal sheared off and is inside the head?

Get an Easy-out bit (or even a flathead screwdriver bit) and put it into an electric drill on reverse -- should bite into the fragment and unscrew it from the spark plug hole.

Wow... never seen that.

For future reference - the torque spec is down around 25 Nn - really not that much
-Throttle's on the right, so are the brakes.  Good luck.

I tapped it out with a flat head screwdriver. Came right out and didn't even need a drill. Thanks!

That's a new one on me too.  Glad you got it out.  Defective plug?

i am surprised the steel plug threads didn't eat up the aluminium head threads

maybe the plugs are now designed to do that on over torquing?  how cool would that be?

fyi if you have no torque wrench, it's usually finger tight and then turn 1/4th.  the box of plugs i have in front of me has a wordless diagram to that effect.

you can use a plug driver, but turn it with one finger until the plug stops, then turn it with force 1/4th turn.

The damn thing cost $10 too! Just another part of the ridiculously large amount of money I've spent on this thing this week.
Anyone know the gap on these things? I've heard 6-8mm but I still want to check in case i mess up again.

6mm gap? 

that's some damn high voltage, how big of an alternator do you run?  2kW?
