Message: [QUOTE="01RM250K3, post: 1254032, member: 77978"] hi i was just wondering if polishing my intake and exhaust ports on my 01' RM250 would do anything performance wise. I would like to do this myself because the intake and exhaust ports are very porous and rough and i would like to smooth it out. i was just wondering if anyone has any tips on how to do this like what type of grit to use for sandpaper and if anyone has pictures on before and after polishing that would be great.
