kx60 piston and cylinder match

[joshmay02]

i got a kx60 and needed a new cylinder and piston. i got a 42.95mm kx60 piston and am lookin at a cylinder witch says 43mm will this fit proporly??????

yes, it will, the piston is made a hair smaller to allow it to expand as it gets hot, otherwise you would probably seize the engine as the piston expanded without any clearance.
