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.
I can’t imagine riding without one and the ease of tuning with elevation change.
Quick to install and made adjusting my fuel screw FAR easier. Plus, it comes in a color to match my bike. Would definitely recommend this!
