Power Valve

[88 Turbo Coupe]

What will I gain or loose if I install a PV on my 250r?

[ATCR250R]

I believe the power valve is to just broaden the powerband and that you should not lose any power when having one compared to not having one.

you will lose some top end power, but in the end you will get a much easier to ride motor and it will be much smoother, it won't have that huge hit. It wells worth it.

You dont loose anything on top, You just wont feel the hit anymore. All a pv does is give a 2 stroke insane torque, If done properly it will ridejust like a 4 stroke. If you drag race its defently not worth it. Mx riding or trail riding its well worth it. You will not gain any Peak hp but you will get a torque monster 2 stroke.
