The higher the octane, the greater resistance to detonation or dieseling. It takes more engery from heat and spark to get a complete burn. If there is not enough energy to ignite the air fuel mixture you will have an incomplete burn which leads to carbon build up not only in the cylinder but in the exhaust.
This is especially true of our carburated bikes. We dont have an engine management system like the fuel injected cars of today. They can sense the cylinder conditions and advance or retard the spark as necessary.
If you have a stock engine (CR) and no timing advance then use 87. If you are using anything else you are wasting money and possible carbon build up in your engine. Not to mention causing more pollution due to the unburnt fuel into the atmosphere.
Do a search on google for recommened Octane and there is plenty of stuff :eusa_dance:
The reason I posted is my CR is 12:1 and running an advance curve. Wanted to make sure I wasnt pinging (dieseling) on my brand new engine
Thanks for all the help.
