Sounds like a nice ride. Congratulaitons ! What type of riding do you do (dunes, woods, desert, trails, track..)?
Boyesen rad valve is definately my favorite. It has an aluminum body intead of the stock rubber intake boot (much better looking, lasting, and less air leak problems). They are Carbon Fiber reeds which last quite awhile, depending on hours used. You can flip them over every season to keep the curve to a minimum.
The V-Force are good also, but you have to cut and modify your stock intake boot to use them. They are carbon fiber also, but there are double the reeds (not necessary in my opinion) and they are not held in by screws any more (not very durable/safe in my opinion).
Usually a pipe (Stock Silencer is best), reeds, and jetting will give you enough power.
