Am reviving a V reg Cb250N. It is now looking superb and decided to fully rebuild the motor so it goes as good as it looks. Had a nice fresh rebore +0.5 and want to fit new valves and guides. The thing is that after fitting the guides I need to have the seats recut because they are not great and also to ensure they are concentric with the new guides. I have found the very odd size reamer need for the guides, but can find know one with the correct size cutters and pilot. I can’t be the only person to ever attempt this in the modern era! Can anyone help me out here?
