Okay i gather its a magnito of some sort, My questions is do i need it? will the motor still work. Im going with friction drive, i removed the middle bolt on the spinning part but the whole fan like casing didnt come out. I thought maybe i could remove it and allow my spindal (bike peg) to go further into the motor area because it is much longer than i need... OR should I bolt a flat straight bar to the 2 holes on the fan part. drill a hole into the center of that bar and attach peg that way? Thanks!
