Gene Davis and Larrie Schneider ran Ocelot Racing, Inc, of Madison, Wisconsin. In addition to producing the Ocelot chassis, Ocelot engineering modified over 130 Suzuki GT-750 engines over a time frame covering from the early 70s to the mid 80's.
These Ocelot/Suzuki engines ruled DSR for many years, until the more powerful Kohler (140HP) came on the scene. Several DSR National Championships were won with Ocelot Suzuki engines.
Note that the Ocelot made even more power than the factory TR750 due to larger carburetors and a full 750cc displacement compared to the TR's carburetor size, limited by Grand Prix rules, and 739cc displacement. Note that with the horsepower listed below, Ocelot engines put out 2.5 HP/cubic inch or 150 HP/liter in the mid 70s! Ocelot made two basic race engine types:
A 750cc "regional" engine good for 110-115 HP. A 1978 pricing sheet from Ocelot shows the "Introductory" 750cc engine at $2,463
Their killer 850cc 130HP "national" engine. The same 1978 pricing sheet from Ocelot shows the "National" 850cc engine at $3,545.
Modifications:
Ocelot engines included these changes:
a modified TR-750 porting (similar to the Suzuki GP bike racing version)
a "squish" head offering a small combustion chamber.
un-tilted the outboard spark plugs.
initially used the German Krober ignition type, then later change to the Lucas RITA LR105 (Racing Ignition Transistor Amplifier).For more pics see
