Motorcycles with two-stroke engines are now a completely endangered species. However, with a number of deep-rooted fans around the world, the technological innovations and advancements in the aftermarket scene have been greater than one might think. It's been almost 20 years since domestic models disappeared from manufacturers' catalogs, but the two-stroke fans are still very much in love with them! Fans of the 2-stop sprinter are especially enthusiastic!
Thorough maintenance is naturally combined with high-performance engine oil additives, which were not available in the past, and an overwhelming number of users are taking care of their engines.
High-performance engine oil additives are a favorite of many 2-stroke engine fans. Moreover, they have an extremely high repeater rate, so when it comes time to top up the engine oil, they say, "I always use it! Many people say, "I don't know what to do. So many riders are experiencing the benefits of the additives. Not only for the sprinter and sport models but also for the 2-stroke touring models and the more practical models, by using high-performance engine oil and additives, you will be able to maintain a dry exhaust sound without the build-up of oil sludge in the muffler. Let's take a look at these high-performance oils and additives.
Super ZOIL, the most popular of all.
Superzoil for 4-stroke engines was first introduced as a high-performance engine oil additive. More than 25 years after its introduction, two-stroke high-performance engine oil and high-performance additives were also added to the lineup, and by the mid-1980s, motorcycle manufacturers were calling them "two-stroke and four-stroke" instead of "two-stroke and four-stroke" in the motorcycle scene.
If you have a favorite brand of engine oil that you've been using for a while, you can mix it with Superzoil for Two-stroke (silver label), a 100% chemically synthesized, high-performance engine oil with Superzoil added in advance to make it available for sale as Synthetic Oil for Two-stroke. The main feature of this product is the "red oil" that recreates the atmosphere of the 1970s and earlier. At that time, the most popular high-performance engine oil was green or blue, but Superzoil was designed to achieve high performance while being a red oil. The users asked for "high-performance red oil", The manufacturer said, "I'm not going to be able to do that".
Mix it with your favorite brand of oil.
Users who have been using the same engine oil for years may not be comfortable with the addition of additives, even though it's a high performance, however, they will notice the difference when they use it. For example, many people say that they can feel the smoothness and smoothness of the engine oil. If you want to mix it with regular engine oil, use Superzoil for two-stroke (silver bottle).
Use a four-stroke additive in the gear oil
A two-stroke engine requires gear oil as well as engine oil. Superzoil for 4-stroke engines comes in two types, Gold Label, which uses a 10% mixing ratio, and Eco, which uses a 5% mixing ratio.
The gear oil change is to remove the drain bolt under the crankcase and replace it with the old gear oil. If the engine is not warmed up, the oil does not flow well, so it is best to warm up the engine and run it for a while before draining the gear oil, as in the case of a 4-stroke engine change.
- No.1 - High-performance engine oil additive to be used as a "walking stick".
- No.2 - The 2-Stroke engine that makes it easy to feel the difference when driving.
- Be careful not to "drive it too fast" just because it spins well. Running the engine too fast can cause a breakdown.
- No. 4 - An engine that has already failed will never be cured by relying on additives. The mechanical noise is quiet, which is a blessing if you notice the problem early.
In a two-stroke engine, special engine oil lubricates the piston rings, the sliding parts of the cylinders, and the crankshaft bearings. This is because the roles of the "explosive combustion system" and the "drive train" are completely separated inside the engine, creating a "separate chamber" structure. This is why the 2-stroke engine requires special high-performance engine oil that can mix well with gasoline, burn well, and lubricate well. The engine oil in the oil tank is pumped through the oil pump to the intake port, where it is mixed with gasoline and then sucked into the crank chamber (primary compression chamber) for explosive combustion. In many cases, the oil pump function is not installed because of the use of the "oil pump", and some experienced riders run their bikes on "mixed gasoline", shutting off the oil pump when it is not working properly.
Fuel drawn in through the carburetor is mixed with engine oil, which lubricates the main bearings on the crankshaft and the bearings on the connecting rods. Primary compression (compressing the air mixture in the crank chamber as the piston descends) sends the air mixture into the combustion chamber (this process is called scavenging), where the oil component also lubricates the piston rings, pistons, and cylinder walls. The air mixture is compressed in the combustion chamber and then explodes in the spark plug. During this combustion, high-performance engine oil burns well and has the characteristic of not leaving any impurities behind. You may have heard of the carbon and sludge build-up in the exhaust system and chamber, but in the case of the 2-stroke engine, the engine oil burn residue will accumulate in the muffler. When you take off the muffler and turn it upside down, you'll find sludge inside... that's exactly what you'll find.
Using high-performance engine oil will not necessarily eliminate all of that sludge, but using a high-performance engine oil that burns well will definitely reduce the amount of sludge. If there is a lot of sludge buildup and strange white smoke, the problem may not be the oil, but a malfunctioning or poorly adjusted oil pump. Keep in mind that in the case of mixed gasoline, even too much oil mixture can cause these symptoms.
Immediately after starting and for a while after running, there is a lot of "white smoke". There are many examples of this. This is often caused by the re-burning of engine oil and sludge left in the crankcase and inside the muffler when the engine is warmed up. For example, after an engine overhaul, not only the engine, but also the inside of the muffler is poured with a carbon cleaning fluid and degreasing wash, shaken several times, and then drained. By repeating this process and allowing the internals to dry out before assembly, the exhaust smoke will be more consistent with the original condition of the engine. That's why it's a good idea to use a high-performance engine oil additive on a regular basis.
A fuel additive that works well for two-stroke engines that tend to knock
Today's fuel is not as powerful as the old fuel. The combustion power of both high-octane and regular gasoline is not as good as it used to be. This is the reason why you can sometimes hear a knocking sound coming from the engine at the full acceleration in the "torque-ridden" timing range. In some cases, it's not the carb setting, it's not the ignition timing, it's the gasoline that's causing it. Superzoil's "Fuel Tuner" is a popular product that improves the ignition performance and eliminates the knocking sound by adding the right amount of fuel to the fuel on the market. In many cases, when you notice the knocking sound, you can improve it with fuel additives.
