You’ll need a guage similar to this one found on the Comet site.

If you feel comfortable pulling the head off and can torque it properly back down, pull the head. Check for damage. If you want to be a little braver, pull the cylinder, but careful not to damage the base gasket. If there is any damage, pack it up and sent it to a shop. At this point, it doesn’t make sense to just hone the cylinder and put a new piston and ring in. There might be issues with the bottom end of the motor, the lower end of the rod, the crank or crank seals. I assume you do not have the tools or expertise to open the crank case. A failure in the bottom end could be fatal for the engine.
There are many good kt-100 builders up here in the north, including mine, but you probably don’t want to spend the money to ship it. Try calling TS racing in Homestead. Not a very long drive for you.
