I had Eric Gorr punch out my 02 kx cylinder to a 265,good mod,but i wanna try the 310.My question is will a 99 kx 250 cylinder fit my 02 kx,because I might have one available but I am pretty shure that in 02 kawi changed the powervalve so i am not shure if my linkage is gonna work with the 99 cyl. ?Also ,can Eric rework my 02 265 and turn it into a 310 ? Any imput will be greatly appreciated.
