Works as intended but....

The only issue I had with it was the fact that the numbers didn't line up like other brands.
On most aftermarket fuel screws the number one faces the user when bottomed out. This one started at 3, small gripe but still seemed odd to me.

It gets the job done

It's a fuel mixture screw.....makes it a ton easier to adjust your mixture without any kind of special tool. However, compared to others on the market, the knob is thin so it's a little more difficult to grasp. Also, it doesn't come with the spring, washer or new o-ring so be sure not to lose or damage the originals when you take the factory screw out.

This is a quality product. My only complaint is that it's hard to get to the screw for adjustment after installation.

Screw backed out

i had to ziptye the screw once it went past a turn and a half out. If not the screw would work itself loose and fall out. Save the time and hassle and by the Flexscrew that is for sale on here.

Great Purchase

Easy to install and adjust on my CRFX 450 with included instructions. Fits snug and has stayed secure. This part should come on a stock bike. Small blemish on the anno, not a big deal.

Makes Life Easier

Easy to install, easy to use. The design and large numbers makes it easy to keep track of how far you have adjusted your mixture.

one part that you just have to have on any 4 stroke bikes should have them as oem.

Works Great

Does what it was designed to do...makes small adjustments to the pilot mixture easy when the engine is hot. Looks good and seems durable. Install took about two minutes. I don't have a whole lot of time on it yet but it hasn't backed out like some other posts.

Simple improvement

This fuel screw has been a great improvement. No special tools are needed to adjust mixture. Even though mixture is set by rpm, the numbers on the fuel screw are a nice addition for keeping quick adjustments simple.

Extremely Useful

I'm not sure how I went without this product for years. Actually I do... I made one carb adjustment for dirt riding in the summer and one adjustment for ice riding in the winter. Now I can make minor low end (pilot) adjustments in literally 3 seconds and do so all the time.

This product actually helped me learn more about jetting because it is so quick and easy.

The o-ring and spring from my stock screw fit right on this fuel screw, and the fuel screw fit perfectly in my carb.

I'll be buying these for every bike I own from now on.... every bike that has a carb.

A: oh yeah its ez . the best way i have found how to get the stocker out is to use a bit from a cordless screwdriver it is short enough to get under the carb but not hit the motor. be care full not to lose the spring washer and o-ring from the stock one you have to use them on your new screw. hope this helps.

A: It can be done with the carburetor on the bike but it is much easier to do it with the carburetor off. You must be very careful as there are 3 small items( washer, spring, o-ring) that sit up inside the carburetor body that can be lost very easily. If you can have the carburetor turned upside down when removing the screw it is almost impossible to lose track of these pieces. Sometimes they will stay stuck in the carburetor and it is just as bad to have extras stuck in there, as not having them all in there. If you do install this with the carb on the bike, it is a good idea to put a white rag on top of the engine case under the carb so when you pull the screw if the those items happen to fall they will be caught. Sometimes they can fall out and you wont even notice it as they are so small and think they stayed in body and then with the new screw installed the bike runs poorly due to an air leak there. Just make sure to keep track of the items so you can assemble the new screw like the one that came out and you should have no issues.

Q: Where can you put this?
Over 6 years ago
Can you put this on the stock carb of a CRF 250R 2006 Model? Does this replace the jets? if not how do you put it in and what does it replace on your old carb?

A: It goes in the very bottom of the carb. Right now you will see a tiny brass flat-head screw that is a pain to adjust with a screw driver. Remove it, and it looks like the top half of this fuel screw. The bottom half sticks out of the carb for easy tool-free adjustment.

Over 7 years ago Location: Portland, OR
A: That doesn't make sense, I've never heard of the fuel screw being inside the fuel bowl. How do you adjust the fuel mixture than? I looked up the schematics of the carb on your bike and it doesn't show it in the float bowl.

A: reference your service manual for the actual spec on the factory setting. I've always been told that if you have to adjust the fuel screw out more that 2 full turns from MFG specs you need to rejet the carb.

A: put new screw in all the way back out 1 1/2 turns test throtle for bog keep going out till you get no hesitation. if its colder the screw will be turned in more and as it gets warmer out back the screw out. its a moving target ride to ride if the temp isnt the same.

A: once you install the product just screw it all the way in and back it out the factory number of turns. usually 1.5-2 turns out from seated. after that just make small adjustments until throttle response is optimal. its a piece of cake and the instructions are detailed and well written.
