Boring Bit
When boring out a broken Spark Plug, what size bit should be used when tapping for the next size bigger plug?
I have a spark plug that broke off in the manifold. Only the threads remain. I plan to drill out the old plug and re-tap the head for a larger plug. what size bit and tap should I use on a 87 kawasaki 600r? Remember this is a metric.
STOP. Before you go to reboring or helicoil, try to remove the fragment of the old plug with a broken scew extractor, (looks like a conical coarse thread screw with a reverse thread). The fragment is already hollow. All you have to do is insert the extractor. Tap it a few times to 'start` it. The apply a wrench and you should be able to screw that 'lil bugger` right on out.
Also note: spark plug thread sizes are pretty close together. The right size drill for the new threads might not remove all the old threads leaving you with a botched head. If you have to drill, helicoil is the way to go. They'll tell you the proper drill size on the package.
