mcman56 Posted October 22, 2021 Report Share Posted October 22, 2021 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? Quote Link to comment Share on other sites More sharing options...

mcman56 Posted October 24, 2021 Author Report Share Posted October 24, 2021 Can 1976 Honda valves be resurfaced? It sounds like some valves can not. Quote Link to comment Share on other sites More sharing options...
phiggs Posted October 26, 2021 Report Share Posted October 26, 2021 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. Quote Link to comment Share on other sites More sharing options...
