Pro Tuning Tips For Your Go Kart Engine
Tuning racing go kart engines yourself is an important and needed component of maintaining any good engine for a go kart. While relatively tiny, these motors can pack a punch when they’re tuned to tight performance standards. It just takes a bit of smart planning, for the most part. Now, there are normally four separate types of these motors which need to be looked at.
The first type of go kart engine is very popular, and it has a bore made of aluminum - called a cool bore - with roller bearing on either side of the crankshaft. It’s very high-performance, though a little rare and maybe not worth all the trouble it would take to get one. The second type can fill in just as nicely, and it features bore made of steel with the same roller bearing set up. Also, it can win just as many races.
The last two types are both single roller bearing examples, though one has a steel bore and the other an aluminum one. The bottom line is that all four of them can produce great performance as long as they’re built up correctly and then maintained and tuned properly. Remember to always perform regular oil changes without fail. After the oil change, remove and inspect the engine’s spark plug, taking care to look over the plug’s electrode for carbon accumulation and scoring. Replace it, if this is present.
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 air filter comes next. Remove and inspect it for excessive dirt or clogged-up surfaces. Replace it if required. You can take a compressed air hose and blow out any light surface dirt from a filter that’s not excessively dirty and keep using it until it is. Now it’s time to check the fuel-air mix of the carburetor. Tighten the needle valve all the way down and then back it out about 2.5 turns, which should make for a perfect mix of gas and air. In-depth tuning with a timing light can be done, too. Just download a guide for doing so and follow it to the letter.
Tuning racing go kart engines yourself should be an activity that any serious go kart enthusiast takes the time to 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. All it takes is a little time and patience to have your go kart engine running like a top.
