It woke up my YZ!
Got my 2000 YZ 250 out to freshen it up for spring. It has alway ran pretty strong with a hard hit but seemed to drop off a little to quickly compared to some of my other bikes. I figured it was time for som new reeds and since my intake boot was looking ragged I bought the Boyesen RAD Valve. Very finely made 1 piece billet including intake which should last forever. Dropped the main down to 170 and retained the 50 pilot. Set needle center slot. I could not believe how strong the mid and top end is now! You may may not like the loss of traction. It’s a little wild but if you are just playing you will love it. Worth every penny.

Rad valve
Dramatic difference over stock , increased power and throttle response across the board , can’t go wrong installing one of these on your YZ 250!
