### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Jetting
  

*by A***R on Reviewed in the United States on March 17, 2022*

I was a bit wary of ordering some jets made in China, but I didn't have a choice as I needed to re-jet my carburetor quickly instead of ordering jets from JetsRus. I swapped out my main and pilot jet with this kit in my FCR equipped DRZ, and I was impressed. Everything went smoothly, and the jets worked perfectly fine. I am keeping the rest in my pouch for future trips with altitude changes for some jetting on the move.

*by K***N on Reviewed in the United States on August 3, 2022*

Be carful before you buy if you don’t know what the jets look like if it’s a fcr 39 off of a yfz only the main jet fits the pilot jets is to small in this package the jets work fine tho

### ⭐ 1.0 out of 5 stars







  
  
    These are not jets for a Keihin FCR-MX.
  

*by J***T on Reviewed in the United States on June 2, 2022*

It claimed these would fit a FCR-MX.  The slow/idle jets are for an FCR, not an FCR-MX.
