No need for anything higher. I ran 89 in my old stock 12R, ran awesome. Alot of Busa guys run 87. It only needs enough so that it doesn't detonate, anything more is overkill.

RFG gas = Ethanol mixed with gasoline.
It's required in the DFW area.
I'm still looking at all the "facts" to decide whether it's a good thing for Hi-Perf engines........

Chevron 89..............tried 87 and it was fine, but when it was really hot out I did not want to risk ping from bogging :-)

87 octane all the time, lower octane you can run without detonate the more hp it will make. Also ran 87 in my two Busa's and my zx12 and zx10

I've heard that 89 octane should generate a little more power than say 93 octane. Can anyone elaborate on this? I know in a car designed for say, 87 octane, this can be true but I didn't expect that to be the case with the ZX-14 since it says 90+ only.
89 octane is certainly cheaper and I could use the few extra bucks in my pocket with the miles I've been clocking. Put 1100 miles on my bike in 3 days.

the more volatile( lower falsh point ) the more power it generally will make,
... that is until detonation occurs.
high octane additives are to prevent detonation.
I ran regular 87 octane till 1st week of september, then the refineries musta started cheaping out, removing less of the butane, and the death rattle came.
In winter refineries typically remove less butane from the gasoline because it allows cold engines to start easier, but really hurts performance of high compression engines, and to deft ear can burn up pistons

why would you run the cheap gas in your precious 14? i run 93 in all my vehicles, i live in florida where heat and traffic can occur daily, if you get stuck idling and your motor gets hot you are a candidate for detonation or pinging. also if cheap gas makes more power how come all racing gas has higher octane(100+)
you might save some pennies but it will cost you big if you burn a piston
in my humble opinion....

Bigdtd, you could not be more wrong, the good race gas for bikes is MR9 and it is 87 octane, and for me it's not about saving money the bike makes more power on 87 pump gas then 92 or 93.

High octane does NOT mean better performance
quote:
... how come all racing gas has higher octane(100+)
Uhhhhhhh. that's not quite true. The most common race fuels found at a CMRA road racing event would be one of these four...
MR9 - MON Octane: 87
MR9 is for all classes in AMA Pro Racing that allow leaded race fuel. Dyno tests have proven an 8-9% increase in power over pump gas.
MR10
MR10 is our newest fuel for 4-stroke road racing where lower octane can be tolerated. It's targeted to make the most horsepower under AMA Pro Racing leaded fuel rules. Dyno tests have proven up to a 2 horsepower increase over our MR9 in 1000cc bikes and a one horsepower increase for 600cc's. This translates to as much as a 10% increase in power over pump gas, meaning nothing on the market makes more power than MR10!
Because the octane rating of MR10 is lower than MR9's, it may not be suitable for higher compression applications.
U4 - MON Octane: 92
Used in stock and modified 4-stroke applications, as well as stock 2-strokes. Makes up to 6% more power than pump gas and any basic nonoxygenated racing fuel. Passes fuel rules for AMA amateur racing and is also perfect for club level racing, CCS, CMRA, WERA and AFM. For optimum horsepower and performance, do not store this fuel in vehicle drain fuel system.
C12 MON Octane 108
Recommended for CRs below 15:1, satisfying the needs of 75% of today's race engines
So what is the most commonly used of the four? Most of the top teams use MR9. They would use MR10, but it was not easily available during most of the season. U4 would be the next most common because it is about 30% cheaper ( U4 @ $15 per gal. vs MR9 $24 per gal. - retail). So much for low octane equaling "cheap gas" (yes, I know you mean at the pump). You won't find many using C12 since it does not give much of a benefit over pump gas.
So the best VP fuel for road racing (MR10) has the lowest octane of all the fuels commonly used in AMA and club racing. I used to think that the higher the octane, the better the performance. That is not true. On the other hand, if your bike spends a lot of time in stop and go traffic and your engine temps tend to run substantially higher than normal, a higher octane could be beneficial. Something like 89 octane would likely be more than sufficient in almost all street applications... including stopped in Florida traffic.
VP's "Street Blaze" fuels are geared more for highly modified or turbo applications. A bike in basically stock trim would have little to no benefit using these fuels.
NOTE:
The Research Octane Number (RON) simulates fuel performance under low severity engine operation. The Motor Octane Number (MON - what VP uses) simulates more severe operation that might be incurred at high speed or high load. At the gas pump, the octane of a gasoline is reported as the average of RON and MON or R+M/2. The R+M/2 number will always be higher for these fuels. Still, the R+M/2 of MR9 and MR10 would likely be below 100.

Interesting Dub...........I noticed my 10R raising HELL last ride on the same 89 that I always run.. I guess during the cold months I need to step it up some. I didn't know those Bastids changed how they refine from month to month...... Bastids!!!!!!!!!!!

MR9 = How much a gallon and how hard to get?
I run 89 octane and never have pre-detonation.
I will try 87 next tank and see, I only get 90 miles a tank these days so its not like I have to run it long if it pings.
Maybe if I shift I will save some gas.

well next time try 87, but only a gallon.
Go around the block vary rpm, and engine load.
likely you will know the first intersection you pull away fro if it will ping.
If it does then top it up with premium.
the death rattle will kill you motor in short order!
ring lands disintegrate, and holes burned in pistons, damaged/ bent connecting rods and wrist pins.
combustion is taking place while the piston travels upwards still in to the explosion, rathger than down with the power stroke!
Nasty stuff!

MR9 is usually sold in five gallon cans (and 15 or 55 gallon drums), but some local dealers will sell by the gallon. The retail price for MR9 is around $24 a gallon, but many dealers will sell it for less.
The nearest VP distributor to you is Downs Energy in Corona. There number is 888-810-3835 or you can e-mail them at rons@downsenergy.com. If they do not sell to the public, they can tell you where the nearest local dealer is.

I guess CrotchRocket and kawasaki_rick who stated they use it were talking on the track only.
$24 a gallon sheesh.
I thought he was asking about daily driving.

yeh drag racing only for my 14. or you could call it suzuki eating . I get it for free also. I haul my buddys bike 2 the track for it. Only thing i hate about it is gotta drain it out, and the smell. My garage is fumigated with it after i use it.
