how can i tell if this old do a standard motorcycle spark plug hole 250 cc yamaha motor

You need to find the thread diameter size of your spark plug. Look up what NGK plug will work for your bike and then check this site: https://www.math.uwaterloo.ca/~rblander/NGK.txt Field one of the NGK code is thread diameter size. Then get the appropriate helicoil kit. Remove the head before drilling out and repairing the threads or you will get metal shavings in your cylinder and ruin your engine.

They are made from Chrome Vanadium Steel. I’ve used my set several times now and it’s a decent quality kit.
