How To Tune Go Kart Engines

Learning how to properly tune a small engine on a go kart is an important step in maintaining your kart. These engines, while small, can be tuned to quite a high level of performance if done correctly and with some planning. Most engines are of four main varieties, so let’s take a look at them first.
The four types of engines start with the most prized, which is one of double-bearing specifications, and with a bore made of aluminum and a crankshaft featuring a roller bearing on either side. It’s a little rare, though, and maybe not worth the hassle. This is because an engine with a steel bore and a twin- bearing set-up is just about as popular and useful, and it wins many races, too.
The last two engines consist of engines of either aluminum or steel bores and a single roller bearing next to their crankshafts. Any one of these four engines can be very competitive if they’re built up properly and then tuned correctly. As for tuning, keep in mind that the most important activity - after regular oil changes — is the inspection and care of the single spark plug. Remove and inspect the plug on a scheduled basis, taking care to examine the electrode for signs of carbon build-up and any burnt or scored surfaces.
Always check the distance between the plug tip and the electrode. Usually, the gap will need to be between.025 and.030, according to engine specs. Take a gap tool and space it out or close it in, if necessary. After that, insert it back into the engine and then go over the plug wire’s surfaces for cuts or abrasions. Any damage to the wire can cut down on top engine performance.
The engine’s air filter will require an examination and a light cleaning with an air hose, most times. If it’s too clogged or dirty, just throw it away and put a new one in. After that, check over the carburetor fuel-air mix, making sure the needle valve is tightening all the way down and then turned back out 2.5 turns. This should serve to give the carb the proper gas and air mix. Once that’s completed, timing can be checked with a timing light and a ‘how to’ guide.
Practicing tuning and adjusting your go kart engine is a skill every hobby go karter should learn. Keeping a properly maintained and race-tuned engine up and running will help contribute to the enjoyment many people derive from racing these little motors. Perform regular maintenance and tuning schedules, though, to ensure top performance.
