The popular inline spark checkers typically have a problem fitting to a spark plug cap of the type used by the KLR and most motorcycles. The bike spark plug does not use the thread on end so the spark checker won't slide into the KLR spark plug cap.
These are available everywhere at a good price so I used my bench grinder to roughly grind the end of the tester small enough that a threading die could cut some threads.
This allows a standard sized spark plug end to be threaded onto tip when using the tester or remove the standard adapter from the tester and place onto the spark plug when using on a bike.
Reminds me to pick up a hand full of these as face palmed a while ago at a friend's marine shop. He had six of them on an outboard which had an intermittent miss. Much better than moving one around (smacking forehead).
One can put one of these onto a bike and test ride to look for misfire although that can become exciting. ;-)
Will try to post a photo which likely won't work because still over limit...
