Skiworx Triple Pisser Kit

To fix a Kawasaki blunder we designed a water bypass kit that will allow the rider to watch the cooling bypass of all three of their cylinders. From the factory Kawasaki only installed one in the front and the rest in the rear (where no one can see). Our kit not only relocates them all to the front, but it includes new head fittings that are straight not 90 degrees which can clog up. This is a must have for any Kawasaki 1200!

Note: This is a complete kit we have taken the guess work out of it. Remember the head fitting MUST have the correct ID or the craft will go into limp mode for an over heat condition.


Skiworx Stinger Exhaust Mod

The Skiworx Stinger mod will help your Ultra accelerate much quicker. This mod is simple to install. It does require you to remove your stinger and send it to us for the modification. The modded stinger section will be sent back along with a complete kit and detailed install instructions.

Skiworx CV Carb Mod

Our exclusive Skiworx CV carb mod is the real secret to making power with the Kawasaki 1200. Over the years many have tried to use aftermarket flame arrestors with CV carbs and have seen disastrous results. With this CV carb mod you will now be safe to use PROK (modded by us) FA's. You will need to send us your carbs and stock flame arrestor for this mod. If PROKS will be used we will not need your stock FA.

Note: We do not sell any parts for this mod outright. We also don't recommend this mod unless the compression has been raised. Before sending any parts please click here .

These are the only flame arrestors we recommend to use with the CV carbs. We mod them to work correctly.

Skiworx Blue Print Pump Work

One of the biggest performance gains on an Ultra 150 is in the pump area. The mixed flow pump uses shims to set impeller clearance. From the factory this clearance along with inferior pump seals can cause a huge loss in performance. Our blue print work includes proper shimming and installation of bearings and the correct seals.

Note: Price does not include bearings and seals. Before sending any parts please click here .


Skiworx Ultra 150 Pump Bearing Kit

Kawasaki has had major issues with the Ultra 150 bearings and seals since day 1. The problem has been inferior seal design. This problem can now be fixed with our bearing and seal kit. We prefer to install these parts in house, please call for more info.


Solas 16/20 Blue Printed by Us

Not all Solas are created equal. We check all impellers before shipping.

Note: The Ultra 150 uses a mixed flow pump that uses shims to clearance the impeller. For best performance we recommend having your pump set up by us. See our blue print pump rate above.
