4 DIY SOLUTIONS AT NO COST TO SAVE YOUR KARTING DAY WHEN IT RAINS

What to do if a day in the kart, which started out in the sun, suddenly turns rainy… And you have nothing with you to face a session on a wet track? Going home may seem like the only option. But that's not the case. With a little ingenuity, some duct tape and a few objects recovered from the toolbox or the pile of "things to throw away", you can implement 4 do-it-yourself solutions to continue driving even in the rain, even if you don't have specific accessories (which ones are there? We suggest some in the "Must Have | Raining all of a sudden? Here are 5 accessories to adapt your kart to wet conditions just in seconds"). From protecting the airbox with recycled objects to emergency covers for electrical components, these are quick and accessible interventions for everyone, designed to protect the kart from sudden rain and not waste a day on the track.
 

Editor's note
It must be said that certain wet track conditions can pose real risks to the integrity of the engine. Driving in the wet is not in itself so harmful, especially if the engine is well protected, if you take some precautions (for example, after washing and final drying, turn on and warm up the engine in the pits on the trolley before dismantling it to go home) and if you evaluate the real state of the engine before going out on the track. It is equally true, however, that if the engine already has hours of operation behind it, or if you work to the limit with the airbox uncovered that is hit by water spray, the risk of damaging the engine is certainly there, especially for Shifter engines, which are very high-performance. So, in certain conditions, driving in the wet can lead to having to spend a few unexpected euros, but it is not a fixed rule that "rain = engine to be redone".

N.B. Do you think there are other products that can be added to this selection? Do not hesitate to share them with other TKART users in the “Contributions” section at the end of the article. The community will be grateful!

Deflector for the intake silencer with the conveyors positioned towards the front of the kart

Protecting the intake silencer is essential in case of rain, because the entry of water or debris can compromise the operation of the engine, reduce its performance or, in the worst cases, cause serious damage. A simple and effective DIY solution, particularly useful for those who use airboxes with conveyors positioned high and facing in the direction of travel of the kart – such as the CIK-FIA approved Power by KG Karting models (for more information, read “Tech Focus | POWER: the new airboxes by KG ”) – consists of making a deflector using a plastic bottle or a plastic bottle for lubricating oil (both empty, of course!). The procedure is easy: just cut the container with a cutter and shape it to obtain a sort of “shield” or “lid” that covers the opening of the airbox, but without obstructing the flow of air. The size and shape of the cut must be carefully calibrated: too large could reduce the effectiveness of the protection, while, on the contrary, too small risk limiting the air flow needed by the engine. A crucial detail is the orientation of the deflector. To work best, the cut part, which acts as a shield, must be facing the back of the kart, so as to cover the airbox inlet. The intact part of the container - i.e. the bottom of the bottle or flask, which must remain intact - must be positioned towards the front, i.e. in the direction of travel. In this way, the air continues to circulate, while water and debris are diverted away from the intake point, ensuring protection without compromising the engine's performance.
