polini big valve kit

[hybridrazz]

What kind of top speed gain could i expect with a 21mm or 19mm,and the polini big valve kit over my 17.5mm and stock reed block with carbon reeds?

i dont know how much faster your bike will be faster, but it will be a lot faster from mid all the way up if set up right. the bike will also be louder from because of the carb noise. what pipe are you using, i hope a race pipe.
