Ultra 150 Carburetor Question

I have a question about CDK II carbs, I have found little performance info on these aftermarket carbs. I want to upgrade the carbs on my Ultra 150, but i dont want to spend a ton of money and have to change the fuel system on my ski. The changes have to be done with the 48-50 style carbs. I have a few mods done to the jetski , and I feel it is time to upgrade the ski. I have a Billet head 165psi, Inland Jet exhaust mod, flame arrestor, Solas DynaFly 16-20 impeller, Shredmaster ride plate, Solas Intake grate and Aggresser Sponsons.

Hi Steve,
The Mikuni 48mm Blackjack carbs with Inland Jet Manifold works great on the Ultra 150. I would also recommend V-Force Reed valves for extra rpm. Plus, a set of 1.5 inch air filters. Its not cheap but You will rule your local lakes....
