The most sensitive adjustment on the carburetor for ease of starting, and this makes it simple to adjust for temperature and altitude. Just keep track of the starting point, and move up/down as needed for current conditions.

The site said fits my bike but when I tried to turn it out to factory settings. It fell out when I was looking for the rich stumble and lean stumble. And I think its walking out of adjustment
Does what it says makes adjustment effortless 03 crf450r
can't ask for more
I would recommend this item to anyone looking for a Fuel Screw for their caburator.
These WILL turn themselves loose. Thought i sucked dirt into carb because suddenly ran very poor. Took it and did complete clean. Ten mins on track next ride and same poor running started again. It had actually come all the way out and was laying on case under clutch cable. I strongly recommend the flex jet. It bolts to carb and cant come loose and much eaisier to adjust.
This is junk it doesn't even screw into the carb. I took measurement with my digital capliar and and are not the same as the stock brass fuel screw. I would never buy anything turner again
no problems at all. makes getting that air fuel mixture right that much easier
No performnace gains, all for looks
easy install and works great
