Iwould not install a rad valve on a motor with a stock pipe,, spend the money on a pipe it will be the best increase for the money you can buy,,,

i have a stock 86 250r i put a fmf pipe on BIG difference i even went back to the stock silencer ,, i like the quiet!!! it is way better even with the old silencer!!

OPPS,,,as far as jetting you might have to play with it a little to get it dialed in
