Tried out a UL-1 motor in my Revolt 30 this morning. All things being equal, but the new motor, I was 7.4 kmph faster than with the 1800kv motor. 80.7 kmph total.

Only one problem though. I ordered a new water jacket (AQUB9518 - stock I piece) and it's not sealing well to the motor body so water is leaking out. The o-rings look good but the jacket when installed, moves relatively easy around the motor body. The factory 1800kv motor + water jacket can't be moved. Which is normal? Any suggestions to create a better seal?
