Hey, I remember a while back someone asking what the differences were between the sx and es motors, well over the weekend I found out one major different..... the crankshaft is a different size.

The SX crank is BIGGER than the ES crank.

I was trying to put my SX clutches on an ES bottom end and no go.... I had to get an ES clutch to put on it....

Thought I would let you all know.....

good find, yes good find.. the rocker arms and the gearing are the only things i can add. (besides the color)
