Comments On Apr 30, 2013:I ride between 2,000 and 10,000 feet elevation so I need to be able to adjust the fuel mix easily. This does the job well.

Comments On Apr 10, 2013:This is one of the best purchases I have made for my bike. I jetted my bike and this allows me to adjust the fuel ratio without having to take apart my bike.

Comments On Mar 18, 2013:Seems like a must for a crf250x (or any bike) if you live in a place with huge temp and elevation swings throughout the day like I do. And it won't just fall out like some of the other fuel screws.

Comments On Feb 07, 2013:A little more expensive than other fuel screws, but it's worth it. It works great and makes tuning that much easier.

Comments On Jan 28, 2013:Makes adjusting the fuel mixture easy. The only problem I've found is that if you don't move the screw every so often, it winds up being really difficult to turn. Without this product though, you'd have a hard time turning your fuel screw.

Comments On Apr 27, 2011:This is definitely a slick setup if you need to make adjutments to your idle mixture screw. I've spent years burning my hands and arms trying to squeeze tiny screw driver bits under my carbs, and this is remote adjuster setup is well worth the money. Now I can tweak my mixture screw without even getting off the bike.

Comments On Sep 14, 2010:This thing works great I love it, I picked up another fuel screw and the idle mixture was off, went to this model and it is perfect just like my stock screw, with the added bennifit that I dont have to burn my fingers and stand on my head to adjust it! 2008 CRF 250X.

Comments On Sep 11, 2009:Once you get this thing mounted it works great! Be careful of two things, however.
First, when trying to screw it all the way down to set your initial mixture be aware that the flex part of the product will twist off and break. Don't force it. It doesn't have the same "bottoming" out feel that the standard fuel screw has when it can't be tightened any further.
Second, make sure to count how many turns you are coming out. Don't come out more than about 3-4 turns or you run the risk of everything falling out and your bike stopping. When you're out on the trail this can be challenging to find all of the parts again and get them put back properly. I would like to see R&D create a way that the o-ring, washer, and spring can't be lost off of the end so easily. My two cents.

Comments On May 06, 2009:I bought this in hopes of making my life easier, but it needs some adjustment to make it right. Super hard to turn after 2 weeks, so it needs to be oiled after every ride for smooth operation. Maybe a make a different mounting location or something
Additional Comments On May 21, 2009:It's a good idea and works well as long as you keep it lubed well. After one week of riding and washing I coudn't even turn it with pliers. I had to take it all the way out and re-clean and lube. Now after I clean the bike I have to spray it down. It's been another 2 weeks and all is well.

Comments On Dec 27, 2008:Works great and came with everything I needed. Makes adjusting the fuel screw easy and has a little resistance so no worries about it turning while you ride. It would be better though if the knob was easier to grab with cold callused fingers.

Comments On Jul 04, 2008:Flex Jet is great for on the go fuel screw adjustments. It mounts perfect on the outside of your carb, stays in place, and is easy to turn. I wish they made one for my four wheeler too.
