How to remove carbon from valves?

Recommended Posts

I'm trying to clean the valves on an old TL250 but am not getting much progress.  I have been using oven cleaner and the intakes are getting pretty clean but not the exhausts.  Is there a better way?

Can 1976 Honda valves be resurfaced?  It sounds like some valves can not.

A kitchen knife would work OK, if you can sneak one out of the kitchen.  To resurface the valve you grind a new surface into it at the correct angle, usually 45 deg.   There are many Heath Robinson ways of doing it, if you don't have the correct machine.   Don't forget to lap the new surface into the valve seat with grinding paste, for an air-tight seal.
