psyco33,
I am assuming that you are running an SA-200 and I know that they all burn a little different as far as heat goes, but it sounds like your machine may be set a little too hot in the OCV's. My SA-200 is set at 92 OCV's and I run my root at about 45-47 in 3rd gear......with my hot pass at about 55 in 3rd gear with a 1/8 5P+. If your OCV's are too high you will risk burning out any electrical appliances (grinders) that you run for extended periods of time........I know because I lived the nightmare of replacing triggers in my grinders (Makita 9005B) just about every month or so.
Just my two cents, hope this helps
