Part 2: Karting and Winter, and everything you need to know, with Lorenzo Travisanutto
Some Advice

In the first part of our special on setting up karts in winter, Lorenzo Travisanutto, our expert, unveiled the first guidelines for going fast with low temperatures.

Where to resume our talk? The fact that, if the front was too loaded, with too much downforce, you could run into a problem. Let's see what and then continue with the analysis.
 
Too much downforce: «An overloaded front end results in an all-too-precise front and also oversteer. To avoid this consequence, you can tighten the rear track; reducing by 0.5 centimeters per side is enough to raise the rear and not force the front too much when cornering. The counterpart in this sense is entering a turn; if the wheel rises too early, the effect is sliding on entry. If it happens, it is good to go back inside the tent or garage and re-enlarge or widen a little."
 
The devil is in the details: "Other small measures could involve widening the front to give it more potential and, having less distance to travel in the turn, you could even reduce the gear ratio to a minimum. But on this, one must be careful, since it depends a lot on the situation of the track. Considering that the engine in winter has more performance, if the track is very smooth and you can bring a lot of speed in the corners, then the ratio can even be lengthened. If instead you cannot have the above effect, then you have to shorten it.»
 
Carburation and bearings: «Carburation, this must certainly be increased because the engine heats up and varies a lot with the passing of laps. Finally, it helps balancing the setting of the bearings, you can try to pull or release accordingly to put the front in a position to lift the rear.»
