The range of Kart Briggs is among the cheapest on the market in terms of running costs. This was possible thanks to the adoption of the Briggs & Stratton 206 engine, a 4-stroke engine that guarantees almost endless reliability and minimum costs of ordinary maintenance. But the regulatory project on which CRG has focused from a technical point of view to design this low cost category is also based on other choices capable of containing costs such as, for example, the adoption of tires with an excellent quality / cost ratio and the it is forbidden to replace the technical accessories of the frame provided with the standard equipment. In any case, we are talking about a kart born for use on the track and which, therefore, requires a minimum of maintenance to always be at its best in terms of performance. With the technical help of Marco Danieli, Racing Kart manager, dealer and team of the Briggs Kart Championship series, we have identified 5 checks to keep a Kart Briggs always in perfect maintenance. Some of these interventions can be done independently, but for better Kart management the advice is to always contact qualified personnel.
1.Check valves. It is recommended every 5 hours of use and to do it properly you need a centesimal comparator. The piston must be brought to the TDC (top dead center) and at that point check the valve tolerance by placing a gauge between the valve head and the arm of the rocker arm. Briggs & Stratton through its use and maintenance manuals recommend a tolerance of 7 to 10 cents. The adjustment must be made by means of the balance screw and, once completed, the balance nut must be tightened and the cover must be refitted. This is the classic operation that, for those who are unable or lacking the correct instrumentation, we recommend that you entrust the expert hands of a mechanic.
2.Carburettor cleaning. It must be performed after each day on the track, in particular we recommend cleaning the part of the guillotine and inside the tray with a simple spray for cleaning the carburetor. Attention: never leave petrol in the tank at the end of the day.
3.Bleeding and brake control. We recommend to bleed the Mini / FS4 Senior brake system at least every 5 hours of use, especially if you notice a slight increase in brake pedal stroke. An oil change every 5 hours is also recommended, while a general overhaul of the system with change of seals is recommended every 15 \ 20 hours.
4.Tire change. In the Mini it must be done after about 70/90 laps of the track as the Vega SL10 adopted by regulation is of very soft compound and prone to wear out quickly. As for the Vega FX adopted in the upper classes, we have noticed that consumption is very low and the same set of tires can last for 2/3 races. For a mixed use between races and tests it is possible to consider about 250 \ 300 laps on circuits with an average length of 1000 meters without significant drops in performance.
5.Engine oil and crankcase inspection. For an optimal engine efficiency, we recommend changing the oil every 4/5 hours of use, while for engine seals (cylinder head, exhaust and valves), we recommend approximately 10 hours of use. As for the base, our data indicates that an engine can safely last for 10 races and related practices (over 50 hours of use on the track) without any drop in performance and, even if these are fairly subjective evaluations, beyond that you should consider to completely change the basement (which Briggs & Stratton sells as a kit with the name Shortblock) to make up for a natural drop in power that the engine could suffer.
