110 main or 140? Got pics of your porting job? Original Keihin carb? 28mm maybe a little big. Where's your needle clip at? Maybe drop it one (raising needle). Check for air leak at carb mount.
I finally got it with a little more adjustment and dropped the needle to the 4th pos. Dropped the main to a 135 and it works great
