OK,,Here is what I know to this point. If I am not 100% right I am very close.

There is a BME 115
It will have a different case design than the 110 so you can run conventional stand-offs without the fully supported ring mount.
It will have a larger/different carb
It will "possibly" be LIGHTER
It might be smaller in some dimensions
It will run stronger than the 110 (of course it's a 115)
I believe it will run the same jugs
It will have all the good characteristics of the 110 with some being better

I hope this will not turn into a my motor is better than your motor thread. This is just for informational purposes only.
