I’m looking for someone to cut the valve seats on a drz400 head to match new valves.

Can anyone recommend someone in the country that could do this? Preferably a place that does regular work on bikes?

I’ve tried a couple local places so far (Wexford) and they’ve said they can’t do it without lapping which can’t be done on bike valves as the coating will be ruined.

Cheers 👍
