Hi all, I recently purchased an ex race bike F4i which came with a TON extra of parts. Among them was an extra complete engine. The problem is that the complete engine has a spun bearing somewhere in it, and as I was trying to disassemble it I ran into a section in the manual which simply stated to use a "special tool" to remove the flywheel. Im using a scanned copy of the manual and cant really see what it is. Does anyone know how to get it off and if I do really need a special tool?
