sounds like a bad head gasket possibly
If your 2 stroke dirt bike starts to smoke really bad that means you have to much oil in the fuel or the wrong kind of oil. Or the pistons, oil rings or cylinders are badly worn.
40:1 is the mixture of gas to 2 stroke motor oil (only)
What's does the fuel valve do on a 49cc dirt bike
It's how the engines work. for the same amount of power, a 2-stroke will be lighter, smaller and rev higher. It'll also use more fuel and pollute more. A 4-stroke will run cleaner and more efficiently. It'll make more torque but won't rev as high.
A 125cc dirt bike typically runs on regular unleaded gasoline with an octane rating of 87 or higher. Some models may require a mix of gasoline and two-stroke oil if they have a two-stroke engine, while four-stroke engines use straight gasoline. Always refer to the owner's manual for specific fuel requirements for your bike.
A 2-stroke dirtbike will be powered by a 2-stroke engine and a 4-stroke dirtbike will be powered by a 4-stroke engine. For the same power, the 2-stroke will be a lighter bike. For the same weight, the 4-stroke will be a weaker/slower bike. The 2-stroke is likely to use more fuel and make more noise. The 4-stroke will run cleaner and quieter.
i use a 5 gallon jug and do a ratio of 40 to 1 its a little rich but will run good
No, you should not put 2-stroke oil in a 4-stroke dirt bike. 2-stroke oil is designed for engines that mix oil with fuel for lubrication, while 4-stroke engines have a separate lubrication system that uses engine oil. Using 2-stroke oil in a 4-stroke engine can lead to improper lubrication, increased smoke, and potential engine damage. Always use the recommended oil type specified by the manufacturer for optimal performance and longevity.
To convert a Razor dirt bike into a gas dirt bike, you'll need to replace the electric motor with a small gas engine, typically a 49cc to 110cc two-stroke or four-stroke engine. This involves removing the existing electric components, modifying the frame for engine mounting, and ensuring proper fuel and exhaust systems are installed. Additionally, you'll need to upgrade the bike's brakes and suspension to handle the increased speed and weight. It's crucial to check local regulations regarding modifications and safety standards before proceeding.
Its like having no oil in a nornal engine... No lubrication, it will stop dead an be pretty much unfixable
yes all Yamaha dirt bikes are fuel injected
The oil fuel ratio for a 1977 Yamaha IT 175 dirt bike is typically 32:1. This means that for every 32 parts of gasoline, you should mix in 1 part of two-stroke oil. It's important to use a quality two-stroke oil to ensure proper lubrication and performance of the engine. Always consult the owner's manual for specific recommendations.
