Ok, now this is something I've been thinking about for awhile. Porting and polishing the head. My question is dose anyone know much about this on the mt09? Is it pretty rough in there? Dose the intake and exhaust ports need much cleaning out? Is the inside of the combustion chamber very rough...
The grove that I'm talking about is two rectangles on the inside of the swing arm that the brake calliper slides into to stop it moving, it can be hard to see you have to get up real close and you will see.
Have you recently removed your rear tyre? If so make sure the rear calliper is slotted in to the grove on the inside of the swing arm, otherwise it can rotate then when u brake it snaps against the stop.
