Well I just spoke with Jet Performance in Huntingbeach and they said for $495.00 each he could set-up two 650 DP 4150 carbs matched to the motor's cam, and both identically tuned together, and for another $250 each, powder coat the body and metering blocks, then chrome the bowls base plate and linkage NOT BAD FOR the kick ass river image everyone looks up to. Plus they warranty the work..Call them up 1-714-848-5500, they want your cam specs before they will build you your carb, can't beat that kind of meticulous attention...What do you guy's think?
