no extended swingarm for me. waste of $$ IMO. its money i could put toward that 240 kit with port/polish. i just pulled the head apart last weekend to inspect the piston and cylinder and it is still showing honing marks all around the cylinder walls. i dont know if that is a good thing or a bad thing. its a 2003 model and is still running on factory bore/stroke. no scuffs or visible wear marks at all on the walls.
