i did the dyno stage one on my o6..save your money and buy mikuini jets(check this site for size recomendations)
with the dyno kit the ONLY advantage for me was the
new neddle with adjustable clip.(no spacer filing)....you do get a certificate for a free dyno run but the closest one to me is four hours away and what would i do with it anyway??
i ended up using the largest main jet from the kit and finally ended up with an exhaust i like,k&n drop in filter,
irad plug...
bike goes in for fine tunig at the dealer this thursday they got the right meter(O2 ?) now so no more guessing on my part..
if i had do do it all again id go the cheaper route and spend the money on something else ...
