I am assuming you have the old BME 115 designed and sold by the previous owner of BME.. I don't own one but from what I have read here on RCU is that the redesigned BME 116 is doing very well. Maybe you should have sent your engine into BME and let them do the mods. Also if I had an old BME 115 I would be very happy that someone took over the company so that I would have support for my engine. The new owners of BME took on a big task cleaning up the previous owners mess and I applaud them for that and wish them success.
