The majority of owners manuals don’t tell you what octane to use, they only say: unleaded gas. If this is all that your owners manual says, or if you don’t have one, keep reading. But if it mentions a certain octane of gas to go with, use that, your motorcycle may require a higher octane due to high compression. If your motorcycle has a turbo, a supercharger, or nitrous oxide injection, then this does not apply to you. motorcycle accessories You should know all about fuel mapping by now (if you don’t… learn!)
If your engine is heavily modified, with high-compression pistons etc, you will need to use a higher octane as well.Ok, so, if your motorcycle owners manual does not tell you what to run, you do not have a turbocharger, supercharger, nitrous, or really high compression in your motorcycle, then: There is a big misconception that you should run the highest octane you can. This is incorrect.
Octane: the amount of resistance to detonation Higher Octane Gas: More resistance to detonation,Lower Octane Gas: Ignites easier and makes more horsepower, assuming no detonation is present. Detonation: when the air/fuel mixture ignites too early and causes a tremendous increase in pressure in the cylinders.Honda Motorcycle Parts If this continues for a long period of time, it can permanently destroy the motor.
However, most motorcycles are made to run 87 octane gasonline, and will not experience any detonation, but will actually LOSE power by running a higher octane, plus it will make it run hotter as well. Check the tank:If it says: 90 ((RON+MON)/2) – Use 90 octane or betterIf it "knocks" or "pings" at all, increase the octane until it stops.
Knocking and pinging: During detonation, when the explosion occurs it creates a shockwave that reverberates inside combustion chamber and raises the pressure immensely, creating a metallic "pinging" sound. If you experience this, stop the motorcycle immediately, Wholesale Motoring Parts turn it off, put a higher octane gas in your motorcycle.
Being a blawger is like being in charge of your own personal insane asylum.
