Responsive
put them in with a new piston. in my cr 125. first weekend, the bike ran good. but bogged in low rpms. after READING the calibration chart that came with the reeds. a simple 3/8 turn in on my air screw, the bog came right out. gained some torque in bottom end. and the power band is deffinatly twice as responsive.

Great service
Order was processed quickly. Being able to find the reeds for my motorcycle which is a 1994 model was a plus. The reeds made a noticeable improvement in power. Almost as much as a pipe and porting

I have a 2006 YZ125 with a full FMF exhaust. I bought these power reeds after reading the reviews and they were right. This is probably the cheapest way to get the most power out of your bike. I think it's noticeably faster. The power band is way more aggressive and it feels like it has better throttle response. The installation was a little hard, but nothing crazy. I had to take most of the rear of the bike off to do it, I'm sure theres an easier way though.

BOYESEN ROCKS!
These reeds work great!! The dual stages help smooth the power band while also increasing power on my yz250. I put these reeds right in with no jetting modifications. Instructions included for easy installation. Great set of replacement reeds for the money!
Overall
Awesome Improvement
Replace the stock reeds on my '03 Yz85 with these and WOW what an improvement. Response off-idle is great, but also top end was increased. I think it made more of a difference than the FMF pipe I put on my bike.

Do the boysen reed valves fit 03 kx 65?
have stock valves in the bike looking for a smoother hit from the power band so that 9 year old racer can build confidence when cracking the throtle

They do make the Boyeson Reeds for the kx65, by installing these reeds you will get more throttle responce.
