The O-rings of the water pump mounted directly on the axle increase water cooling on fast tracks

There is always something to learn, especially from the best, indeed, the most experienced. TKART asked them to help clear up some of the doubts of kart drivers. Six quizzes, which at first glance may seem simple, but which can sometimes deceive even the most experienced drivers. Here are the questions in this article:





1. DOES MOUNTING THE O-RINGS OF THE WATER PUMP DIRECTLY ON THE AXLE COOL WATER MORE ON FAST TRACKS?



2. ARE THE PLASTIC CLAMPS THAT TIGHTEN THE BUMPER AND ATTACH TO THE CHASSIS USED TO MAKE THAT AREA STIFFER?



3. IS IT ADVISABLE TO SET A NEUTRAL CAMBER IN THE EVENT OF RAIN?



4. IS IT NECESSARY TO BRING THE STEERING WHEEL AS CLOSE AS POSSIBLE TO THE BODY TO MAKE DRIVING A KART LESS OF AN EFFORT?

And here are the answers!

The (theoretical) consequence is that in doing so...
