Sounds Like your main jet size is Already too small , Bump it up to a 280-290 And Plug chop To confirm
Edit: See you say airbox delete , you should add 2 main jet sizes for that mod alone , Plus the Pipe adds another 2 mains , you might need a 300 or bigger if its cold enough where you are .

The only True way to be on Top of your jetting is Plug Chops and knowing your motor is leak free , I would Say get sizes from 260-300 and plug chop to confirm proper jetting for the weather .
You were probably on the edge of lean all summer. Personally I'd start with 300, even if it's rich it will be good if it gets colder. BE AWARE!! you can cold seize even if you are jetted spot on and warm it up. My son seized his WOT 6th @0*f or below on the lake. If it's real cold rigg some card board to sheild the engine
got all brand new seals on top end did the rebuild bout month ago took it out first time we got like inch of snow to go drifting was running fine goin down the road but as soon as i went to get on it in the feild started boggin at high rpms like that. idk it rain fine all summer till cupple days ago before n after rebuild
That seems almost worse than jetting issues then , Maybe do a compression check on it , Kick it at least 10 times With the Throttle Wide open the whole time .
