Luciano Medeiros from LM Motos in this program shows tips on maintenance and lubrication of your motorcycle's chain. Motorcycles use three types of power transmission from the engine to the rear wheel: drive shaft, belt and chain. All three types are good, but the one that has the lowest cost is the one that uses a chain and for this reason it is the most common in motorcycles of all engine sizes. However, this economy comes at a higher maintenance cost. The model that uses the chain is the one that requires the most maintenance. There are three situations where maintenance should be done immediately after use: excess water, beach sand and mud. Motorcycles that run on asphalt tend to comply with the recommendation of checking the lubrication status every thousand kilometers driven. But this will depend on what you use for lubrication. Some people use white grease -- which is actually for nautical applications and not for motorcycles. It has a problem: it collects a lot of sand and residue and it does not penetrate the internal parts of the chain and contributes to greater wear over time, because when they lubricate motorcycles that use marine grease, most do not even remove the old grease -- they just pour it on top. In another situation, only anti-rust oil is used, which cannot withstand the heat and strong friction of the chain ends up losing the viscosity necessary to reduce such violent friction. Finally, after much research and hearing everything out there, I decided to test on the Kawasaki Versys the model that uses washing the chain with anti-rust and then using W90 or W100 SAE50 oil -- Oil for 4-stroke aviation engines (I use SAE J1899, formerly MIL-L-22851D). Don't think that I used this oil because motorcycles fly. No. The oil used in aircraft engines has all the necessary additives to minimize the effects of friction between the chain and the assembly, since it has an excellent viscosity that is very suitable for this type of transmission. First, place the motorcycle on a stand that allows the rear wheel to be fully suspended. Then turn the motorcycle on and put it in first gear. You may need to ask for help from someone -- in my case, it wasn't necessary and I was able to control the clutch and lubricate the chain. With the rear wheel on, wash the entire chain with anti-rust -- all four sides (don't skimp). The two upper and lower sides -- the inside and the two sides of the chain until you notice a black liquid running down. Wash for another minute and then turn the motorcycle off and let it run down for about five minutes. Once this is done, it's time to add the oil. See the photo. This situation works best if done with the tire spinning. Add two or three capfuls -- release slowly, just a tiny trickle until the capful is empty -- repeat the procedure two more times -- that should be enough. Turn off the engine.
