Yoir running stock boots right. If I put my 38 on my stock boot. I took boot from air box off clamped it to carb first then routed it around shock and reclamped it to airbox. But I had rad valve on my front.  Its a pain in the but. You could get sb design trx adapter plate then you use zilla boots on the 91 92 250s that what im doing on my 91.
