I've seen threads re pre honed guides on the US site... What's the score with these..do these do away with the need for reaming after fitting? opinion seems to be divided?
Trigger:
There is plug and play valve guilds on the market for modern heads. They come as a set, valves and guilds, even today there are valves on the market that are Teflon coated so, you can't even lap them in. This is all apart of the throwaway society and making engineers in to fitters.
On these old girls, you should use the upgraded valve guides, that have oil seals on all. One of the best I have found are sets from Yamiya. These still need to be reamed with a Honda tool to spec.

Ok 👍 Thanks for that...ill probably end up farming that out! I've never reamed anything and probably not a good idea to start now! 😬
Trigger:
Just make sure that they know about old Honda's and have the right tooling. I spend half my day correcting other engineers work >:( And if they mention that they do brit bikes, RUN ;)
