Factory Effex Fuel Adjustment Screw

Factory Effex Fuel Adjustment Screw

jroe12 - Huntsville, AL EXACTLY WHAT I NEEDED "Bought this for a 2006 KX250F. It fit perfectly, even came with the o-ring, spring and washer required on the KXFs (possibly other models). I cant say enough about how much easier it is to dial in my carb settings now. Very user friendly product. I highly recommend this product to anyone wanting to make adjusting their carb easier. As always with Motosport, shipping was fast and I received my parts in about 3 days. Factory Effex hit the nail on the head with this one. will definitely be replacing my OEM screws with these from now on."

Savery1 - Portland, OR, USA Best on the market "I am just replacing the one that has been on there for 10 yrs now so you know I like it. Beauty of it is, you can adjust your air fuel screw while never getting off of the bike. Perfect."
