Message: [QUOTE="Jkirky, post: 1433809"] Hi everyone... Ive got an 02 kdx200 that im keen to mod... Ive sent out the cylinder to be overbored to accept a 68mm piston, which should convert the capacity to about 215cc or so... Whilst i'm at it, I would like to have a go at some port work. I dont want to drastically change the characteristics of the engine, but just want to improve flow... My idea is to restore the port timing to original spec after the rebore, and smooth out the casting inperfections within the exhaust and intake/transfer ports... Has anyone ported a kdx on this site? Any feedback? [/QUOTE]
