ROBIN 4.5hp

FACTORY DESIGNED FOR GO KARTS & MINI BIKES

3-year warranty

OVERHEAD VALVES FOR EASIER STARTING & SMOOTHER RUNNING

FEATURES:

The engine fits in the minibike and gokarts we sell. Also, gas tank may be removed for installation in a custom minibike frame if you are using a separate gas tank.
This engine bolts right onto most go karts and mini bikes without any modifications.
*3/4" diameter, 2-1/4" long keyed crankshaft
Centrifugal Clutches and Torque Converters for 3/4" diameter crankshafts will fit this engine.
4 Tapped bolt holes around crankshaft. Our Torq-A-Verter kits will bolt up to this engine. Chain guards, etc...will also bolt to it.
Soft pull starter - less pulling effort required to start.
Set up with a spring-loaded throttle return. This is a factory designed throttle return system for a Go Kart or Minibike to allow the throttle cable to return properly

NOTE: This engine is the updated version and has a manual choke. The manual choke allows the engine to be started more easily under most conditions

NOTE: Not just any engine can be used on a Go Kart or Minibike. This engine is factory designed to be used on Go Karts or Minibikes. It has the Throttle Hookup and Spring Return mechanism to help prevent the throttle from sticking in the ON position, a common problem when using a Utility Engine.

Lawn Mower and Utility Engines from other suppliers may cause you to have unwanted problems such as these:

They may not have the proper spring-loaded throttle return for the throttle cable
The crankshaft may be the wrong length and a standard clutch will not fit
The side cover may not have a standard bolt pattern for adding chain guards, Torq-a-Verter kits, etc.
It may also be completely under-powered because of the RPM range of the engine
