6.3. Running-in procedure for the engine

Attention: Pay attention to safety advice of the kart manufacturer.
To ensure that components have the longest possible life span, the engine must be subject to a
defined running-in period at first operation of engine or after a repair of the crankshaft or
displacement parts.
To warrant the best running-in conditions we recommend to fill the fuel tank the first time with
slightly oil-enriched gasoline/oil mixture of 1 : 33 (3% oil).
After the end of the running-in period run the engine without fail on the specified oil/gasoline
mixture of 1 : 50 (2 % oil) to prevent trouble like coking of the exhaust valve.
Attention: Use only fully synthetic 2-stroke oil.
Load and speed changes mean:
Fully open the accelerator until the engine reaches the r.p.m. mentioned above – lift of the
accelerator completely – until the r.p.m. comes down to 5.000 r.p.m. and accelerate again.
After this running-in period the full power of the engine may be used.

The ON/OFF switch serves also as an emergency stop if engine operation must be
interrupted (e.g. carburetor piston stuck in full throttle position).
Close the ignition circuit by the ON/OFF switch only for engine operation. At engine
stop with the ON/OFF switch on, the ignition will consume current, thus discharging
the battery completely this will lead at the end to damage or ruin the battery.
Start the engine and run the kart for 15 minutes at continuously changing load and
engine speed fluctuation up to 9.000 r.p.m.
Then run the kart for 15 minutes with load and speed changes up to 11.000 r.p.m.
trolley) r.p.m. over 13.800 1/min are possible, this dramatically shortens the
lifetime of components (conrod, big end bearing etc.)
