Having jetting issues with my KTM 250 exc 2017. I swapped out the Mikuni for a Keihin PWK 38 and have been sorting the jetting. The bike has what I would call pipe bang or a chugging on de acceleration. I have up the pilot from 42 to a 45 which seems better, but is this something than can be cured by jetting or I have to live with .... it doesn’t seem right..... any jetting advice ? Cheers
