RE: Best 100c class engine?
In that size range, there are plenty to choose from. DA, BME, 3W, ZDZ, Kroma, Mintor 3M. Everyone seems to agree that DA as a company has a history of taking care of you best if something goes wrong with the motor - engine's fault or your screwup. I like the power of my 3W-106, it's a little stronger than the DA. The ZDZ is lighter, and the BME is the lightest - haven't seen any of the latest ones run. A friend has the Mintor 3M, looks beautiful, but don't know how it's going to run or how the company will deal with service - they say it has a lifetime warranty. Kroma, haven't seen one.
