I'm taking a look at a BME 50 that was put in pretty hard. I have not seen the motor yet but a couple of the cooling fins snapped off on the back side from hitting the fire wall. One of the stacks on the stock muffler is slightly bent and the prop broke which may have bent the spindle. I plan to clean it up real good and bench run it and see how she runs. I would like some advice from some of you veterens out there. Should I tear this thing down? How can I check the spindle? Will the missing cooling fins allow the motor to over heat? I noticed there are a lot of folks selling BME's but can someone tell me who services them? I really need to know what kind of tempature range it should be running at. Prop size at what RPM. Come on vets...am I missing anything?
