Boyesen Reeds

I have a 2000 CR250 and I want to improve the low and mid range power and throttle responce.

I ride hare scrambles/ single track wooded trails.

First of all can I get the Boyesen Rad valve any more or something like it because I noticed the rubber boot on my stock air runner is splitting from age.

Next which is the best Boyesen Reed to get for improved low and mid range torque and the fast possible thottle response and sensitivity, ( so I don't hit a tree), the Power Reeds or the Pro Series.

Thanks for the answer in advance.
Slam on Dec 9, 2009
BEST ANSWER: Thanks for your question! Unfortunately for this particular model there would only be the replacement pedals, we do not offer the complete assemblies any longer.

Great product
Easy installation, performance is great and even though the manufacturers suggestion is not to modify the reed block the moose racing spacer stretched the power curve from right off idle towards the mid range. Great combination.

Little more low end snap
Yz250 with 295cc big bore. The reeds are reasonably priced and seem to make my bike have a little more snap down low.

Awsome stock replacement
was an easy direct fit replacement for o.e.m. this is the first time ive ever just replaced the reeds on my personel bike ive always just threw in the v-force system. probly still will lol. but i was short on cash so i decided to try them out some of my customers rlly like these so, why not. well after installing them i noticed several things. my throttle response is awsome, the reed valves came with all new hardware except the screw, and it really gave my blaster a nice ping in the exhaust. all n all its not the v-force system but its the closest to it for a stock cage i've ever encountered
