Bamboo sheets are known for their softness and breathability, making them a popular choice for those looking for a luxurious and eco-friendly option.

Cover the valve gear with a clean cloth to prevent dirt getting into the working parts of the engine.
Oil seals work by squeezing and retaining lubricant in a thin layer between the lip and the shaft. Perfect sealing is ensured by the hydrodynamic action of the rotating shaft, which in turn produces a slight pump action.

Regular maintenance and inspection of shaft oil seals are essential to ensure their proper functioning and prevent costly downtime and repairs. Signs of a worn or damaged seal include oil leaks, increased noise or vibration, and decreased efficiency. If any of these symptoms are detected, it is important to replace the seal promptly to avoid further damage to the machinery.
Different types of spark plugs, each with varying heat ranges and electrode materials, can significantly affect your bike's performance Different types of spark plugs, each with varying heat ranges and electrode materials, can significantly affect your bike's performancemotorbike spark plugs. For instance, a colder spark plug can help prevent pre-ignition in high-performance engines, while a hotter plug can aid in fuel economy and emissions control.
However, the new variant also comes with less good properties. Namely less flexibility and less resistance during assembly. Most damages therefore occur during the installation of PTFE oil seals.
Make sure the fuel-pipe connections are clean. Unplug them and reconnect to the pump.
Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.
EPDM oil seals are less common. They are used in solvent, hot water and steam applications, EPDM resists low temperatures down to -50 °C and UV radiation well. Some types of EPDM are also suitable for higher temperatures up to +150 °C. EPDM oil seals are usually available upon request.
