first off, ill say some people have had great luck running mikuni flatslides,i however didnt.
the fuel inlet spigots arent the right size for the fue lline on mine ,the carb bodies are cumbersome ,huge, and barely fit into a banshee frame ,the parts are all special order and alot of shops wont carr y the stuff youl lneed ,the tm carbs have all these orifices and seats i swear these things are like womans vaginas... theres holes ,plugs, drains ,and tubes and shit just alot of unneeded dickin around IMHO ,the Keihin pwks reved faster and smootherand higher on my setup and jetting is a breeze ,plus theres more than 3.5 people on earth who know how to actually get them to run right too! :confused:the flatslides arent like the ease associated wit h the stock roundslides IMHO . :huh:38mm is beyond huge even big for an alky bike. overcarbing your 350 will only make you lose power
