Not only because you can easily adjust it just like and idle screw know, but it also does not back out on its own. I have had a few fuel screws fall out and it sucks. I am pretty stoked on this product. I recommend R&D Flex jet to everyone."

Unfortunately four strokes hae jetting issues...this makes it very easy to adjust fuel screw.....easy to install, and to use. Whether it solves your problem or not, depends on whether you know what you are doing or not....It will not solve issues that require rejetting your carb, but if a simple fuel screw adjustment is the fix, this makes it very very easy...you can do it while still moving, lol...."

The way the carb sits, you can't get to the end of the ...""I bought this from my 2012 WR250F. The way the carb sits, you can't get to the end of the stock fuel screw without twisting the carb. The fuel screw is recessed about an inch into the carb, so you need something at least that long to get to it. Bit the carb sits so close to the engine that you can't fit a small screwdriver in. Adjustment was tedious.This fuel screw is fantastic. There's no reaching under the carb to adjust it like with the other aftermarket screws. The bend of the cable keeps it from rotating on its own. You can also use the logo on the end of the knob to count how many turns out the screw is. This thing is great. It took 15 minutes to put on, and most of that was getting the old fuel screw out."

R&D Flex Jet Fuel Mixture Screw R&D Flex Jet Fuel Mixture Screw R&D Flex Jet Fuel Mixture Screw Padgett243 (Oklahoma, USA) Why did I wait to buy this"This should have been a factory part when carb four strokes came out years ago. Adjusting ...""This should have been a factory part when carb four strokes came out years ago. Adjusting the air/fuel mix is so easy and simple now. No more burning my hand tring to adjust the fuel screw. This product is the fix for carbed four strokes. If your bike has a carb, then this is one of those must have parts. I have installed the R&D Flex Jet on two bike, KX250F and CRF250R and I have had no problems and the parts has worked great. To me, it is a performance item to keep your bike running the best it can on that day. Simple turn of the knob and the bikes purrs like a kitten."

Once this happens it becomes hard to make small adjustments because the screw wants to bend back to its warped position. It worked great in the beginning but its time for it to go."
