I'm in the market for new valves. I'm looking for mostly a boost in the low end performance of my kdx 200, mid and high end would be a plus. Which valve is recommended Boyesen Rad Valves or V-Force Delta 2 Reed Valves? Where is th cheapest pace to buy?
for low end response and better response over the whole power band a get boysen rad valve Jeff fredette recomends this and if you still want more low end get a torque ring from Fredette racing Rad valve is $120 at rockymountainMC.com i got it for 126 dollars shipped
GO to Canadian Dave's "hop up Guide" and read what the final consensus is on the Rad Valve[$160 for no detectable difference] The Boyesen 2-stage reeds will give you increases on both top & bottom ends
