This is such a great product. It is so easy to just reach down and tune your carb. It will never fall out like the last two aluminum ones I had. Don't waste your money on the colorful ones that will fall out somewhere on the trail or track. Spend a little more and get this one, it's more than worth it.
Flex jet mixture screw is a must have. If you are fumbling with screwdrivers, or burning your hands trying too adjust the fuel screw, you need this part. Super easy to install. My only gripe is: I wish the would wrap a rubber band around, or tape the box it comes in. As in my case, the box came open & lost the small washer. Other than that, Great product.
Whoa! Gave my bike too much power. I literally can loop out in 7th gear every time now. I highly recommend this if you are looking to holeshot the finish line jump every single lap in reverse.
At first was a little difficult to adjust but then got it to adjust. Works great, idle is the best its ever been ony 2004 RMZ 250!
Easy to install and makes fine tuning very easy, even can adjust on the fly
If you have a hard to get to mixture screw then you're going to want this. It makes adjustments EASY as can be. If you ride in different altitudes as I do you need this
I cant say enough about motosport.com . I work on powersports for a living and they always have the parts i need at great prices to keep my business running smooth and my customers happy. The R&D flex jet is perfect for my customers who ride in all types of weather with dialing in the carb for temps and elevation at your fingertips. Its a must for any FCR carb!!
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
They might have something for you.
