Incorrect sizes
These are not made to correct specification. I needed to go up jet sizes but the #20 was about half the size of the genuine Mikuni jet that I removed. The #40 in this set was the same size as the genuine #20, meaning there was no option for me to increase jet size.Images show genuine #20 jet on the left and the #20 jet supplied in this kit on the rightWill be returning for a refund
