i dont think the v force reeds can handle the extreme cold weather at all and the cold nitrous destroys them had a set of v force 3's in 02 ski doo 800 it was 56 below without windchill started up the sled only had prob 50 miles on brand new blew the left reed cage compleatly out locked up my motor will never put v force in anything i ride in cold weather again lucky for me it just barly got the bottom of piston half day in cold woodshed got sled going again 600 dollars later finished up are riding trip!

martinfan30:
So the concensus seems to be the Boysen dual stage reeds are the best for offroad?

I hope this isn't too OT, but what is stock HP for a 2000 KX5? What would this reed kit add HP wise?

GDubb:
Stewarts dyno says the VF2 are the best for power gain... The only bad thing I have heard about them is in regards to cold weather or nitrous as stated above. I'm sure anything is an improvement over stock.

Charlie500:
VF2, only way to go. unless you ride in -30 degree weather or your drag racing with nitro.

 Hey Don, don't some guys inject the nitrous after the reeds? or does that throw a different curveball into the mix?
