Thanks for all the great tutorials! If I do not intend to take the valves apart to lap them, can I still still do the buffing wheel technique to get rid of the carbons on the valve and the cylinder head?
That is great point and not covered in the video so thanks for bringing it up. Since valves did not have any free play in guides, engine was not using oil nor did we notice any “blue” smoke, the conclusion was that guides were ok and did not need replacement. If any of these symptoms appeared during inspection, we would address them. Also, if you decided to send the heads for complete restoration, guides would be replaced at that point together with valves, exhaust seat and springs. None of that was done at this time since it was working properly. Thanks for watching!!!
This was cheap tool from amazon: www.amazon.com/Orion-Motor-Tech-Compressor-Motorcycle/dp/B08FZWQGF2/ref=mp_s_a_1_3?crid=3NATH2K9VGC6V&keywords=valve+spring+compressor+tools&qid=1668656670&sprefix=+spring+compressor+tool%2Caps%2C127&sr=8-3 I wouldn’t recommend it if you plan to use it regularly. In that case get something more quality.
Great video,thank you

Most likely even though you might have some small remaining carbonized part where valve meets the seat. Thanks for watching!
How about checking /replacing the valve guides ,surely that is more important than getting the heads clean

What grit do you recommend for the buffing wheel?
Gold (120 grit) seemed to work the best for me. Thanks for watching!
Where did you get the spring compression tool?
