your main seems real lean to me. With my 28mm on watercooled 70 in Ohio - a 42 pilot and 128 main w Amsoil 50:1 is about right. Now, your cold weather will change things. Your main will go up in numbers as it gets colder.

I have always wondered why mine was so high on the main. On our 90 malossi, 28 carb, hag intake and pcs pipe my main is 148, pilot @ 45, needle in the middle.:huh

The quad runs fine, the plug is dark tan, never oily or wet looking. The throttle response is fine......148 sounds crazy though.

Our polini built 50 has a 120, 45 and needle in the second slot. Plug looked good.

I WOULD START AROUND 125

My 2fast with Haggerty was good right around a 138 main. All running C12 w Amsoil at 50:1.
