True or false? The experts answer to karters doubts.
1.An industrial drier can be used to heat the engine crankcase to facilitate inserting the bearings.

Explanation by: Alessandro Marrapese, owner of the Marra61 team, team manager, engineer and telemetry expert… A true “jack of all trades” in karting..

“When warmed up, the crankcase seat expands and facilitates the insertion of the bearings.

The task takes about five minutes for each side of the crankcase. We recommend you keep an eye on the time to ensure the surfaces of the seats are heated evenly.

The same trick can be used when removing the bearings to avoid damaging the crankcase seat during their replacement.”

2. If the engine is made to run richer there is a risk of breaking the reed valves.

3. A hand needs to be placed on the filter when making the new OK engines run richer, as was the case with the old 100 cc engines.

4. The deflector only serves to protect the radiator from debris thrown up by the rear left tyre.

5. The silencer greatly affects the performance of the engine.

6. A chassis made using 30 mm diameter tubes performs better on very twisty circuits.

Bearings have a key role in the functioning of the chassis, because they reduce friction and the wear of the components. The fundamental ones are those on the rear axle.
