so I polished my ports last summer and raised my exhaust port 1 mm. this is the first time I have had a chance to look at it since I put it back together. this is with about 20 hours of ride time here is a few pics
one question though, on the top of the piston I have two lines in the carbon tha line up with the edge of the transfer ports. now there doesnt seem to be any damage that I can see so I was just wondering what it was from or if its a sign of something
thanks
