How do I know if my snowmobile reeds are bad?
Engine Symptoms Associated with Worn, or Damaged Reed Petals: Loss of horsepower and torque. Engine fails to pull hard at high rpm. Hard starting, and inconsistent idling.
What is the purpose of reed valve?
The reed valve function is to regulate the fresh gas intake in the crankcase and/or combustion chamber of a 2 stroke engine. The reed valve is therefore a key component for the bike’s performance: the fuel supply of a 2 stroke engine gives in fact the power and torque’s output values.
What does a reed valve do in a 2 stroke?
Reed valves are commonly used in high-performance versions of the two-stroke engine, where they control the fuel-air mixture admitted to the cylinder. The resulting pressure differential opens the valve and the fuel-air mixture flows into the crankcase.
How do I know if I need new reeds?
If you’re noticing that the tip of your saxophone reed is chipped, it may be time for a replacement. In some cases, chipped tips won’t affect playing, while in other instances chipped reed tips will make the reed completely unplayable. To verify the extent of the damage, observe where the tip is chipped.
What does a reed valve do on a 2 stroke?
What does a reed do on a 2 stroke?
Two-stroke engines Reed valves are commonly used in high-performance versions of the two-stroke engine, where they control the fuel-air mixture admitted to the cylinder. As the piston rises in the cylinder a vacuum is created in the crankcase beneath the piston.
How does the reed valve in a two stroke engine work?
Reed valve allows the mixture to move in only one direction – from the carburetor to the crankcase. It prevents the mixture from moving back to the carburetor. In the effect reed valve improves reloading of the combustion chamber with fresh air-fuel mixture. This improves power output of modern two stroke engines. Pic. 1.
How many times does a reed valve open?
(3) The reed petals pulse as the engine cycles, at roughly a one-to-one ratio. When the engine turns 8000 engine revolutions per minute, a reed opens 7980 times per minute. Needless to say, when the engine is running close to peak rpm, the reeds are really buzzing.
How does reed valve thickness affect engine size?
We offer high quality, carbon fiber & epoxy based material dedicated to self-cutting of any reed valve petals. We can also develop a material adjusted to particular needs or requirements. Reeds thickness is proportional to engine size and power output. The bigger the engine, the thicker reeds should be used.
How can I tell if my reed valve is damaged?
Typical symptom of reed valve petals damage and/or wear is difficulty to start the engine and uneven/non-smooth working manner. Reeds should be occasionally checked for proper sealing and lack of chipped material or cracks. One of the ways to check for proper sealing is to direct reed valve cone (with reeds outside) towards a strong light source.
What happens when a reed valve goes bad?
The hesitation in the engine due to failing reed valves can be very frustrating as the power is simply not available when needed. If too much fuel is poured into the engine and reed valves are failing, the result may be engine backfiring.

How does a reed valve work in a car?
The block fits between the carburetor and the engine. With a lower pressure zone on the engine side, the reed petals flex open to allow fuel/air to pass, when the lower pressure switches to the intake tract side, the reed petals are forced tight against the reed block to seal off the intake tract.
What do the Reed petals do on a motorcycle?
With a lower pressure zone on the engine side, the reed petals flex open to allow fuel/air to pass, when the lower pressure switches to the intake tract side, the reed petals are forced tight against the reed block to seal off the intake tract.
