Yeah, Grigg you showed us that with your adapter plate. That accommodates Fenton dual exhaust, then the one above works for anything with a triangle mount, which isn't every engine out there, so that's why I made a clamp-on adapter. The only engine we haven't figured out yet is the one with the upside down L triangle.
Bypass owners just need to remember to put a 1/16th restrictor in the adapter somewhere. I tap a stainless bushing 1/2" NPT with 1/8" NPT inside with 1/2" fine thread (only near the bottom) then drill a 1/16th hole through a bolt (the long way), tighten it in good with loctite red, then cut the bolt off. A little tapering around the hole and you are in business. Screw that directly into the Transdapt 1028 in the Outlet and done.
