Boyesen vs V-Force, which vlve is better on YZ125?

[YoTRacer158]

i was wondering if any of you have put either of these reed valves on your yz? how did they affect the power? the dyno charts for the boyesen radvalve seem to show only an increase up top, but icant find any dyno charts for the V-Force

I would reccomend the V-force. Once you have it jetted correctly it improves a little down low. mid and high there are big changes. It pulls a lot stronger. I have one on my bike and i was glad i did it. A fairly cheap investment also.

I agree with marcv125 . I run a V-Force on my CR and can tell you I gained a much broader powerband throughout. I have not tried the Radvalve but have heard pretty much what you saw in the dyno charts. I believe the V-Force site had Dyno graphs ....This should be it www.mototassinari.com
