Yep, I did my Saito 120 with the gold Valve Covers a couple months ago and it was so much easier then working on the OS Engines. My Valves had a lot of carbon on them but cleaned up OK. The one thing I notice about my Saito 120S, which does not seem to bother it's performance, is when cold it does not seem to have a lot of compression. Once started and heated up it pulls like a mule. On the other hand on my 150 Saito you can really feel a lot of compression when cold....it's a beast.
