id these radiators?

[Zakk]

i've had this pair of NOS triple row radiators for a few years and was thinking of fitting them to my YZ250K, as the ones on the bike are a little out of shape. although the 250 has twin row cores and never runs hot so i'm thinking that these 3 row radiators may be too large.
anyway these have the part #12703 and #02803 plus one has KA4 printed as well..






they are clearly stamped L and R, so i think radiator with the filler cap is on the left hand side, unlike my YZ which has the filler on the right hand side.
any one know?

Honda CR250 81-85 has product code KA4,Which exact year model you may find by doing a part # search, Those rads are right side filler cap

thanks for that, so the 81-85 CR250's had 3 row cores standard?. strange that the filler side is stamped L, maybe someone put them together wrong.

KA-3 is 81 KA-4 is 82 they look to be from an 82 to me they look the same pipe arrangement as my 82 125
