The reason why i Change to the Boyesen : The OEM Reed was Scrap , then i Change to Vforce 4 Had 3 broken Reed Pedals in 2 Years so i Change to Boyesen Run the Boyesen on all my Ktms, they run perfekt but the fitment on the 2019-2022 KTM-Husky is Not ok But I don’t know how it looks like with Standard Mikuni and WP Shock
