Ultima HSR 42 mm Carb Kit for Evo 1993-1999
The Ultima 42 mm Carb Kits will enhance the performance of any Twin Cam or Evolution engine in stock or slightly modified versions and are recommended for engines up to 100 CI.
These Carburetors will deliver superior throttle response, fuel economy, starting characteristics and horsepower when compared to currently marketed Butterfly Type Carburetors with bores of 1-7/8.
Ultima 42mm Kits come with a 1.625 I.D manifold to match OEM style EVO and Twin Cam Cylinder Heads, but have a larger 1.880 O.D. This will allow cylinders, that have been ported, plenty of material for port matching and they still can utilize the stock style OEM manifold clamp and O-ring. Twin Cam kits come with Map Sensor machining finish.
Mikuni Carburetors have a fitting in the back of the Carburetor for vacuum operated petcocks or VOES switches.
