Thread: Carb Adapters
10-01-2008, 09:00 PM #1
I contacted Hot Seat and haven't gotten a response back yet so I thought I'd post my question here to get a faster response. Does anyone know if they make a carb adapter for the Keihin carbs to fit on the Hot Seat hi-flow air intakes? If so, does anyone have a set of 3 for sale? Thanks!

never heard of any.when i was doing all the sleeper carbs,which flowed 183 cfm vs 168 stock,the 42's were around 205.i remember the stock intakes were well above that cfm so there wasn't any restriction in the stock intake runners and even the stock cages flowed more than enough air with the ct petals and stuffers with the 42's.the real issue with the stock 40's is jetting with triple pipes and even more so with the reeds. and pop off.the ct light petals i have make for a erratic takeoff from time to time.the heavy tension are a little sluggish,so the v-force with stuffers would be the hot ticket there.my pro has awesome throttle response with the heavy tension setup

Update: Finally heard from Hot Seat, they never made adapters for the Keihin carbs to work with their intakes. I should send them a reply asking why...with so many Polaris watercraft using the Keihin carbs. I think they would of sold more parts overall if they had. I think it would be a rather simple plate part for someone to make...hint hint!..anyone? CrazyA?

the stuffers perform 2 things.1st they smooth out the transition from oval to to square??like port matching,2nd they fill in space that otherwise has to have vacuum created on it.personnally i think the v-force are overkill on a stock,unported motor,or small carbed motor as compared to stock,ie 38mm changed to 40mm,but if the intake tract is opened up(aftermarket manifolds)bigger carbs 44 and up the v-force are the way to go,as far as running keihins on an aftermarket intake??why,the stock intake ported to match a 43mm opening flows all the cfm it can move,only thing i don't like about the stock intake is the short inside radius closest to the motor,but on a bench this was easily corrected.
