Engine Break-In
Breaking in your new engine is critical for proper performance. Failure to follow the break-in procedures can cause engine damage and shortened engine life. Always use a
14:1 gasoline:oil mixture during the break-in process and when running the engine.
If you change fuel or run in dramatically different environments (hot/cold, high/low elevation, etc.) you will need to adjust the carburetor needles to prevent overheating and
maintain proper performance. Never allow the engine to rev freely with the wheels off the ground.
Use the optional Dynamite Pro Temp Gun with Laser Sight (DYNP2000) to check engine temperatures.
Break-In Procedure:
CAUTION:
You must complete the break-in process on a smooth surface, such
as pavement or concrete. Do not drive the vehicle on dirt or grass during the
break-in process; doing so will damage the engine.
NOTICE:
Unlike nitro engines, do not allow the gasoline engine to idle for several
tanks. Allowing the engine to idle prevents the engine from reaching operating
temperature.
Fuel Tank #1:
1. Drive the vehicle in a fi gure 8 for the fi rst tank of fuel. Keep the throttle position
between 1/4 – 3/4 throttle. Do not exceed ¾ throttle.
Engine temperature: Do not exceed
2 0 5 º F ( 9 6ºC )
Fuel Tank #2:
1. During the second tank, move the throttle position between ¼ and full throttle.
Do not hold full throttle for more than one second.
Engine temperature: Do not exceed
2 1 0 º F ( 9 9ºC )
NOTICE:
Engine temperatures are measured at the very bottom of
engine head and not at the top of the head like a traditional
nitro engine.
Fuel Tanks #9-16:
After the end of Tank #8, the vehicle is ready to run on dirt surfaces.
Maintain the same carburetor settings that were used during Tank #8
through Tank #16. After 8 tanks of fuel, you can tune the engine for peak
performance.
Engine temperature: Never exceed
2 6 5 º F ( 1 2 9 ºC )
Fuel Tank #8:
1. Lean the high speed needle 1-2 hours when the fuel level reaches ½ tank.
2.
Move the throttle position between ¼ and full throttle. Do not hold full
throttle for more than three seconds.
Engine temperature: Never exceed
2 5 5 º F ( 1 2 3 ºC )
Fuel Tank #7:
Move the throttle position between ¼ and full throttle. Do not hold full throttle for
more than two seconds.
Engine temperature: Never exceed
2 4 5 º F ( 1 1 8 ºC )
Fuel Tanks #3-5:
1. Move the throttle position between ¼ and full throttle. Do not hold full throttle for
more than one second.
Engine temperature: Never exceed
2 2 0 º F ( 1 0 4 ºC )
Fuel Tank #6:
1. Lean the high speed needle 2-3 hours when the fuel level reaches ½ tank.
2. Move the throttle position between ¼ and full throttle. Do not hold full throttle for
more than two seconds.
Engine temperature: Do not exceed
2 3 5 º F ( 1 1 2 ºC )
