Boyesen Super Stock Carbon Reeds
Brandon in TN
+++
Tried the vforce 4x reeds and they were great but they kind of mellowed out the low-mid punch these fi bikes have. The bike did rev out a little better on top but I felt like it lost too much low-mid. So I put these Boyesen reeds back onto the oem cage and they seal much better. 100% recommend

Tusk Fuel Mixture Screw
Chance in FL
THIS IS A MUST HAVE!
Anyone whose tried adjusting this on a fcr carb, knows the struggle. This makes simple on the fly adjustments easy! Bought for my 2008 yz250f. Simply remove and replace. Your back on the track. The price point is great and the quality of tusk is amazing! I have purchased so many tusk products and I have yet to be let down but the quality and price!
