Nice assortment. I needed a high speed jet but wasn't sure what size and I was able to try a few with this set until I got it right on mini bike. It is a nice quality set for the money.

I wanted to try out a 38 and 42 pilot jet and several main jets on a few different project motorcycles that have a Chinese clone of a Japanese Keihin carburetor.Was able to find out what size jets to order on my next Jets-R-Us order and didn't break the bank doing it.I don't have a micro drill bit set to verify size accuracy, but the 40 pilot jet I tried from the kit seemed to idle and 1/4 throttle the engine the same without touching adjustments on the crab.One motorcycle likes a 38 or 40 pilot and a 110 main. The other likes a 40 or 42 pilot and a 125 main.I didn't test fuel economy differences but the spark plug chop on the pilot jets are about the same color of tan, so I am leaving the richer jet in for a safer AFR mixture at lower altitudes.

I'm no expert when it comes to carburetors, but I have a GY6 150cc go-kart that I installed a PWK carb on. I needed a good selection of jets to get it tuned just right, and this kit has everything I could ever need to tune this carb! As a bonus, it also includes cleaning brushes.The carb jets are all labeled, so you can easily identify each one. The quality seems top-notch, and they fit perfectly. If you're looking for a wide variety of jets for your carb, this is the set you need! It offers so many different sizes and options for both the pilot jet and main jet. Highly recommend!

The jets in this product fit the stock Keihin carburetor of my Yamaha YZ250X. This product is priced at a low cost, making it a good value. As a point of reference, you can expect to spend $10 or more per jet for a genuine Keihin pilot or main jet. I can see two situations where this jet kit would be very good to use. This is good for those looking to experiment with different jet sizes or for those who are rebuilding a carburetor and need to replace jets that are not the factory stock size. I fell into the latter group. I needed to rebuild my carburetor, but all the rebuild kits I found only contained the stock size jets. I got this kit because it contained the jet sizes I needed and also for the included brushes. Prior to installing, I compared the new jets to the old ones and found that they matched up. Installation was easy, the same as any other jet. I used the brushes to help clean the passages in the carburetor. The brushes worked okay, remaining intact when using solvent on them. After completing everything, I took the motorcycle out for a test ride and it went well. I would get this jet kit again.

I recently did a carb clean on my dirt bike and these were perfect for replacing my jets. Everything was clogged and mostly needed replacement, and this kit got it up and running. I've also kept the cleaners which have come in handy on other projects when working with carburetors. I'm overall happy with my purchase and would definitely buy again.
