Hey there, I was wondering if anyone remembers the skyward motors from the 90's......they were black with a large "S" on the side, anyhow I bought a used plane with one and figure on trying to get it running before buying a new motor......I'd like to change out the bearings but the one place that sold this motor in the 90's told me it's discontinued and extra parts are long gone.........any thoughts on the bearing issue would be appreciated, thanks.....................i'd love to see that motor running with the 2 foot tune pipe that was included.............
