I did not think that there was a change so far! (◎ _ ◎;)
I installed it in YSR 80. First, although the appearance is Cut-out's intake man is Parenthesis good. The carburetor Body also gets bigger than expected when compared with OEM's 18 π.. I was able to attach the pon without any trouble in the installation. It is performance, but it is much better startability. OEMcarburetor probably was overflowing (^_^;) I feel that the feeling of Torque has increased considerably with Smooth. I think that you can enjoy even more by packing detailed settings!
