i had a bme 100 that i had converted to a bme 111 and the bme is about on par with the power of an 80-85 cc motor but i think the da-85 can beat or would beat my bme 100. the 102 is close to 5 lbs not sure what a zdz weights. bme has gotton a bad rap in the years for service the company has a new owner who is getting it up and running as we speak. the bme also needs to be prop in the 26 range as it likes to be up in rpm if it were me i would keep my motor or get a super 80zdz
