R&D ULTRA 250X
SUPERCHARGER BELT
TENSIONER WHEEL
R&D has significantly improved the
Kawasaki Ultra 250X’s serpentine belt
tensioning wheel system by redesigning
and precision machining a new tensioner wheel with a larger O.D. The new
R&D Tensioner Wheel offers a wider adjustment range and helps to reduce
belt slippage via more surface area for belt contact. Wheel comes complete
with precision bearing installed.

PULLER TOOL
The R&D wheel puller tool makes it fast and
easy to remove a supercharger wheel without
the removal of the intercooler system or the water muffler assembly. The R&D
Supercharger drive wheel puller will save at least an hour on a pulley removal
and replacement. A must have tool.

WASTE GATE BLOCK-
OFF KIT
The new R&D Waste Gate Block-Off kit
is designed to block-off the inconsistent
OEM waste gate. The CNC machined part allows the supercharger to deliver
its boost without premature pressure loss from a leaking waste gate. Kit
comes complete with gaskets and hardware.

BOOSTGAUGE ADAPTER
The R&D Boost Adapter installs between
the supercharger and the waste gate and
allows the ability to mount a boost gauge to
it via 1/8” fitting. This will enable an accurate
measurement of boost the supercharger is delivering. Kit comes with gaskets
and hardware.

BILLET HUB KIT
The R&D Supercharger Hub Kit will replace
the O.E.M.’s vulnerable part with a redesigned
and beefed up precision CNC Machined
6061 billet aluminum part that is much stronger than stock. The new R&D
design also offers pulley wheel alignment adjustments with a CNC machined
Shim Kit that allows for precision serpentine belt cog alignment. The R&D kit
comes complete with a special tool that will indicate the perfect alignment of
the crank drive and compressor pulleys. At 8,000 RPM, horsepower and belt
life can be greatly sacrificed through misaligned pulleys! The R&D kit offers
superior strength, precision pulley alignment, and extended serpentine belt
life. The all adds up to a powerful gain.

R&D TEMP. SENSOR INTERFACER
R&D Performance offers a unique supercharger air temp sensor interfacer
which may be necessary on some Ultra 250X units. There have been some
Ultra 250X models that will default into “limp home mode” if the charger tem-
perature sensor is peaked prematurely. Any Ultra 250 which as this default
occur on long rides on hot (115 degree) days should install the R&D
Supercharger Temp Interfacer Kit. The Interfacer is an inexpensive fix for
this randomly occurring problem on random boats.
