10PCS Carburetor Main Jet Kit for Keihin OKO KOSO PE PWK Crab Jet Kit 118, 120, 122, 145, 148, 150, 152, 155, 158, 160

I picked these up for a trip to St. Anthony's sand dunes. We ride at sea level. And the dunes in Idaho are about 5,000 foot. My TRX450r needed to be re-jetted. These worked great. I had no problems getting these jets into the carb. They had no issues during our week of ridding in Idaho. And they came out with ease when we where back home changing everything back to sea level settings. Would buy again if I ever needed another set.

Look and fit like stock.

The items ordered came in exactly as described.

I have like 200 Jets in my tool box, these are no different than any of the others

Well they're jets what else is there to say about them lol..

Fit great in my 2002 kx250 Keihin PWK carb. Factory Main jet is 162, so having the 160 and 158 is perfect. The # stamping and "K" logo were smaller than my original OEM main jet, but the dimensions all matched (unlike another Chinese cheap kit I bought..)

These are not Chinese knock offs, they are genuine Keihin main jets. Can’t go wrong. The dealer charged $5.00 each. If you want to retune your setup, this a perfect addition to your toolbox.

I used this product to jet a quad. Jets weren't marked well, few of them were just a guessing game
