0 15 Motorcycle chemicals and lubricants A number of chemicals and lubricants are available for use in motorcycle mantenance and repair They include a wide variety of products ranging from cleaning solvents and degreasers to lubricants and protective sprays for rubber plastic and vinyl Contact point spark plug cleaner is a solvent used to clean oily film and dirt from points grime from electrical connectors and oil deposits from spark plugs It is oil free and leaves no residue It can also be used to remove gum and varnish from carburetor jets and other orifices Carburetor cleaner is similar to contact point spark plug cleaner but it usually has a stronger solvent and may leave a slight oily reside It is not recommended for cleaning electrical components or connections Brake system cleaner is used to remove grease or brake fluid from brake system components where clean surfaces are absolutely necessary and petroleum based solvents cannot be used it also leaves no residue Silicone based lubricants are used to protect rubber parts such as hoses and grommets and are used as lubricants for hinges and locks Multi purpose grease is an all purpose lubricant used wherever grease is more practical than a liquid lubricant such as oil Some multi purpose grease is colored white and specially formulated to be more resistant to water than ordinary grease Gear oil sometimes called gear lube is a specially designed oil used in transmissions and final drive units a s well as other areas where high friction high temperature lubrication is required It is available in a number of viscosities weights for various applications Motor oil of course is the lubricant specially formulated for use in the engine It normally contains a wide variety of additives to prevent corrosion and reduce foaming and wear Motor oil comes in various weights viscosity ratings of from 5 to 80 The recommended weight of the oil depends on the seasonal temperature and the cemands on the engine Light oil is used in cold climates and under light load conditions heavy oil is used in hot climates and where high loads are encountered Multi viscosity oils are designed to have characteristics of both light and heavy oils and are available in a number of weights from 5W 20 to 20W 50 Gas petrol additives perform several functions depending on their chemical makeup They usually contain solvents that help dissolve gum and varnish that build up on carburetor and intake parts They also serve to break down carbon deposits that form on the inside surfaces of the combustion chambers Some additives contain upper cylinder lubricants for valves and piston rings Brake fluid is a specially formulated hydraulic fluid that can withstand the heat and pressure encountered in brake systems Care must be taken that this fluid does not come in contact with painted surfaces or plastics An opened container should always be resealed to prevent contamination by water or dirt Chain lubricants are formulated especially for use on motorcycle final drive chains A good chain lube should adhere well and have good penetrating qualities to be effective as a lubricant inside the chain and on the side plates pins and rollers Most chain lubes are either the foaming type or quick drying type and are usually marketed as sprays Degreasers are heavy duty solvents used to remove grease and grime that may accumulate on engine and frame components They can be sprayed or orushed on and depending on the type are rinsed with either water or solvent Solvents are used alone or in combination with degreasers to clean parts and assemblies during repair and overhaul The home mechanic should use only solvents that are non flammable and that do not produce irritating fumes Gasket sealing compounds may be used in conjunction with gaskets to improve their sealing capabilities or alone to seal metalto metal joints Many gasket sealers can withstand extreme heat some are impervious to gasoline and lubricants while others are capable of filling and sealing large cavities Depending on the intended use gasket sealers either dry hard or stay relatively soft and pliable They are usually applied by hand with a brush or are sprayed on the gasket sealing surfaces Thread cement is an adhesive locking compound that prevents threaded fasteners from loosening because of vibration It is available in a variety of types for different applications Moisture dispersants are usually sprays that can be used to dry out electrical components such as the fuse block and wiring connectors Some types can also be used as treatment for rubber and as a lubricant for hinges cables and locks Waxes and polishes are used to help protect painted and plated surfaces from the weather Different types of paint may require the use of different types of wax polish Some polishes utilize a chemical or abrasive cleaner to help remove the top layer of oxidized dull paint on older vehicles In recent years many non wax polishes that contain a wide variety of chemicals such as polymers and silicones have been introduced These non wax polishes are usually easier to apply and last longer than conventional waxes and polishes
