gjeffers & cumn thru,

Just a note about my Saito 100. I too have a bearing noise in mine, very rough when I spin the prop. I have maybe 12 flights on it. I broke it in as per the instructions. We have had quite a bit more rain for the past couple of years than is usual. So... when the bearings started to make noise I attributed it to the humidity. I just disassembled the engine tonight and found rusted bearings alright... along with everything else in the engine. Cam, crank, rockers. And afterrun oil running out from everywhere. The compression on this engine is awesome. Funny thing though, I also use afterrun oil EVERY time I put the airplane up after the days flying. I never miss this, not on any of my engines. This Saito 100 is the only one I have ever had rust up. Now for the most interesting thing... I also have a Saito 72 that is a year older w/ about 40 flights. broke it in the same as the 100, same afterrun oil and kept in the garage same as the 100 but this engine has perfect bearings, very smooth.

I think there may be a problem w/ the Saito 100's, JMO though. Maybe packaged during very humid weather. I don't know.

This engine is still under warranty but I am not sending it in. I am installing ceramic bearings from Boca Bearing. Maybe I can get a few hundred more RPM's?

Tom...
