how high is too high to run in a bike
-1989 honda cbr 600
runnin 92 daily

 

I've run super unleaded for years (92-93 octane)

 

yup 93

 

I've ran Sunoco 94 and I've ran no-name 89 etc......Can't tell the difference, maybe the dyno would???

 

You can run as high as you want. The higher you go, the less combustible the fuel mixture. How much hp do you want to loose?

 

Nothing but 87 octane in my piece!

 

93 for me. You would figure since we put a beating on our motors that we should put the highest octane. Longevity is the key!

 

87 in my F2. More is just wasting your money.

 

it just changes the flash point of the gas igniting and burning cleaner. with 87 octane you run the risk of detonation with high compression engines like ours....leave 87 to the fiddys and cars

 

87 for me

 

spend the extra sixty cents to fill your tank are you guys that broke or what use 92 it raises the flash point yes to prevent pre ignition on a hot engine or advanced timming or high compresion motor and mine is all three and im sure most of yours are too and it will not take away horsepower that is just not true but if you are running higher octane than you need to you will just be waisting your sixty cents

 

I never run anything less than 89, but usually 92/93

 

i fill up with one or the other haven't noticed any difference between the two

 

I used to use premium but fVck that. i can get more practice in with the cheap stuff.......cant tell the difference

I think the higher HP/bigger the engine---runs hotter....needs higher octane

theres another thread somewhere around here.

 

I run 87 most of the time

 

89 for me

 

Exactly!

 

I read that 89 is the best mix for a bike...not burnin as hot as 87...but has a lower combusting temp than the higher oc's so your burnin more of the fuel with less waist...backfires

 

you know what gas in bikes is extra fun is 110 octane when you can find it. talk about your bike growing some instant *****.....

BTW....yeah gas is more expensive now than ever....but i have to say....40-55 mpg is something ill take every day...and honestly...it costs 7 bucks to fill up the tank unless you run 110 race gas.....

 

running 110 will not make your bike any faster unless you get high compression pistons. It does make it smell good though.
