I can't believe I didn't get this a long time ago!
This makes tuning your carb very easy .you can tune on the fly
Ease of use is amazing! Was struggling to get tuned properly. Made it super easy! Read some reviews 1st, so before install i pulled it apart and lubricated it well. I chose a light thin coat of lithium grease. Havent had any issues yet. And it will not fall out. I am actually kind of glad i lost my spring and washer on my quick adjust fuel screw because i never would have bought this. If you read this review and choose to buy one i gurantee youll be as happy as the other reviews on here. Worth every penny!
No more looking for that dumb red screw. And solved many problems. Lol
Put this on my 08 wr450f, instantly took away the bog when you hit the throttle hard. Just a little tunning and off i went. Feels like fuel injection, well worth it on my bike.
I read a lot of reviews when looking for an aftermarket fuel screw. The stock screw was completely inaccessable on my rmz250 and barely accessable on my crf250 so i knew it had to go.
Some reviews said the longer needle style would loosen up on people which concerned me, and it also would not have fit on the RMZ I'm pretty sure. Had to loosen up the carb clamps and twist it up a bit to access the fuel screw, then just unscrew, make SURE you got the washer and o-ring out, and then screw in the Flex Jet. Put it all back together and was able to effortlessly tune my idle mixture while sitting right on the bike!!!
A absolute must have.
An absolute must, makes air/fuel adjustments in a snap, as easy as pulling out the choke, make it easy on yourself and get this, you will not regret it!
This thing is so simple I'm upset I didn't come up with it........ The R&D works perfectly and makes it so easy to adjust your air/fuel mixture. Great device!!!
Easy to install, easy to adjust, and worked great. I've only had for a month but so far so good.
This thing is awesome. I ride high mountain trails one weekend and then head down to the coast to rip the sand the very next. This thing makes it cake to get the machine dialed in for the elevation. A few turns one way or the other and she purrs. Real stylish to.
Awesome product went in great and works great. It's super easy to adjust it.
Makes adjustment super easy should come factory
one of my best buys! I can tune my carb for different riding conditions with ease.
After messing around with stubby screwdrivers on the trails in the mountains for a few months, I finally broke down and bought one. Really glad I did because now I can adjust my air screw much easier and therefore am more likely to do it before every ride as should be the case. Much easier to lean over and adjust this than to stop the bike, get off, get tools out of my pack, start the bike, fumble around with a short stubby screwdriver trying to find the fuel screw and slot, adjust the carb, stop the bike, dismount, stow tools, etc.....
One negative is that the tip is not identical to the keihin, and a pilot jet change may be needed to get back in the correct adjustment range.
I would buy it if your thinking about it, definitely worth it, don't worry its worth it.
I have used other remote fuel screws in the past. They vibrate loose and even fall out. If you have a carburetor on your bike this is a must have! Easy to use and time saving so you can ride more. Thanks.
Much easier to access than other fuel screw designs. Just installed, so no rating on durability at this point. However, I expect 5 stars on that end, as well.
Best remote fuel screw
This is a must for makig your bike run correctly. With the screw installed, making adjustments to the air/fuel is quick and simple. Why a fine motorcycle like KTM does not have this installed at the factory is just too crazy to ask. This the best $20 you will ever spend on your bike. Don't even try to ride without getting this first. It will help you get the "bog" out of your throttle response.
They might have something for you.
