Two Stroke Engine Break In

After engine has been installed and all fluids replenished (coolant/water, gear oil etc) you must then break the engine in properly. Improper break in results in lower reliability and possible engine seizures.

Use the gas and oil mixture ratio that you intend to run after the break in. Check all fluid levels periodically during the break in. Check the carb jetting periodically during the break in.

Part 1

Idle: Start engine and let idle with a fan blowing on the radiator to help it cool properly. Let idle for 15 minutes.
Cool Down: Shut engine off and let engine cool for a minimum of 30 minutes.
Idle: Repeat first step.
Cool Down: Repeat second step.

Part 2

Note: Be careful not to put unnecessary strain on the motor during the break in. Do not climb large hills or go through deep mud. If possible use a mild treaded tire. If you are on the sand do not use sand paddles.

Ride: Ride for 15 minutes varying your RPM not to exceed 50% of normal riding pace.
Cool Down: Shut engine off and let cool for a minimum of 30 minutes.
Ride: Ride for 15 minutes varying your RPM not to exceed 60% of normal riding pace.

I followed this, except while idling I "blipped" the throttle every 30-45 seconds to speed up the H2O impeller. An idling motor will not sufficiently supply coolant to the motor, which could cause overheating and you do not want that, especially during break-in.
