Yeah, he does it the hard way, as id expect from a diy'er.

What we do is remove the air filter and sprinkle sand at the intake while the bike is running and it hones itself while it runs.

Is really quite easy.

:D

That's why I use a K&N filter.

It hones itself continuously over the life of the engine so it doesn't glaze up.

Many years ago a buddy ground the valves on his 750 Honda with an electric drill and some sort of compass device and ground the seats with old valves cut to an interference angle and lapping compound.  Valves sealed perfectly.

The scary thing is I was almost thinking it was serious.....until I got to the part with the "ring micrometer".
