in cali there are a few gas stations offering 100 octane race gas will that make a differrence? can it harm my bike?

 

I don't see the need for it unless your running a high compresion motor. A stock motor runs good on 87 octane. The higher the compresion the more need for higher octane. I have a stock twin cam and run 89 octane with no pinging and no preignition problems at all. I don't think it will hurt it but just don't see the need to spend the extra $$ for it. MHO

no it will not hurt your bike but it probably not give you better performance I have run it on the street and on the dyno although I know guys who think it makes a lot of diffrence but I lost 3 hp on the dyno tq stayed the same, pipes usualy burn a little white inside if you try it not to worry I know guys who run it alot but more octane does not mean more energy.

 

More than likely you won't see any big gain with a stock bike over using 93 + octane .....but it won't hurt anything either...so knock your self out !

 

Key here is "They Think" it makes a big diff............more $$$$ must mean more power ....LOL ....fact is higher octane combusts at a higher temp .....so you can run higher compresion ratios without detonation problems,it also burns slower and more even.But again the average "stock bike" doesnt know the difference.I believe the white in the exhaust is a result of higher sulfur content ,just a guess !

 

HD doesnt have to mean "High Dollar" for everything...
LOL
