Cylinder head number spark plug

So getting ready to leave work yesterday... Fires the bike up been running great.... Heard a hiss of compression escaping.... Started to take off the boom! Number three shot out.... Anyone know of a quick fix without having to pull the he's we have a week or so worth of riding left maybe more I just want to ride the rest of te season and rebuild her this winter

Two suggestions:

1. Read through the following thread on sparkplug hole repair:

2. Use a torque wrench and follow factory specs for spark plugs and anything else that fastens to the aluminum engine or other aluminum parts. Ed
