Tolulene and other additives do not raise the octane rating. Been tested and debunked many times. Your engine only needs 93, going higher does not increase performance as octane ratings have little to do with how much power is generated and more to do with how much it will delay ignition.
Tolulene will clean up the injectors and system, but too much of that will also dry out the o-rings in the system.

No offense intended here, but you have absoluetely no idea what you're talking about. Debunked? That's total baloney!Toluene and xylene are common industrial octane boosters in gasoline . Here on the west coast, we only have 91-octane gas available as a convenience for the refineries' needs to produce different seasonal blends of oxygenated fuels.A 30% mixture with 92 pump gas will raise your level of octane to about 98 with toluene and 99 with xylene.Off-the-shelf boosters use MMT or ferosene. Older carbon-builtup engines also gain advantages from boosting octane because the added space occupied by the deposits increases the compression ratio. Unocal's 100-octane race gas is already 25% toluene! Do notuse toluene or xylene as boosters if you have catalytic converters or O2 sensors, they can damage them.
Yes, BTW, I am an organic chemist.

Plus one on the "rocket Fuel", that's a brand name not the stuff NASA uses. It works when you can't get the good stuff, and comes in handy single use containers. Remember if you are using a pump that only has one hose you are getting quite a bit of regular befor ethe good stuff gets there. For that reason we know where most of the three hose stations are in our area.

In a stock motor there is no real benefit to higher octane. The motor is set up to operate on a specific octane level. An increase in octane does not always= an increase in performance.

RE: Octance booster
You are right, and I did type faster than my head, I meant/was thinkingacetone. The old myth that adding nail polish remover will bump up the octane rating and it's cheaper. That was debunked on Mythbusters. My bad, but I do have this link to some actual tests on most of the common fuel additives and how much is actually needed to bump up the octane levels.

Exactly what would be the benefit of 99 octane fuel in a stock bike? Even if these miracle snake oils did add octane, how does that increase performance or fuel mileage? Race gas is used in race engines because the compression ratio has been increasedand the timing has been changed. The higher octane means the fuel is more stablewhich helpsprevent predetonation.

I'm going to steal part of it because it does a better job of making my point than I did.[&:]
The important part is that going above the necessary octane rating for the engine will DECREASE performance.[:@]
As displacement, compression, boost, RPM, go up it becomes harder to keep the fuel mixture from igniting prematurely. If under load or high heat, you experience knock with 87 octane, stepping up to 91 octane is logical step for both performance and longevity. If you experience no knock or timing pull at 91 there is no benefit to you stepping up to 93 or higher. The additives that raise octane have less energy than the base fuel, effectively lowering the BTUs of the fuel. That is you will make the most power and have the best fuel economy with the lowest octane that is capable of preventing knock under your specific conditions.

Simply put, increased octane will NOT provide more power or better fuel mileage.
Higher octane allows for more timing, or more compression, without detonation. It is the increased timing and higher compression that provides more power. Not the increased octane.

So?????????? the octane does help increase power indirectly?

Plus one on the "rocket Fuel", that's a brand name not the stuff NASA uses. It works when you can't get the good stuff, and comes in handy single use containers.

For that reason we know where most of the three hose stations are in our area.

RE: Octance booster
No. Higher octane does not mean more power. It only makes the engine make the power it can in its current configuration of compression ratio and timing.You put 92 octane in an engine and it makes X amount of horses. You then put 100 octane in that same engine it will not make more than X asit did on 92 octane.

So?? in the end. If it wasn't for the higher octane the timing wouldn't increase causing more compression without detonation and increased power.

Increased timing doesn't cause more compression. You are getting confused with two completly different things.
If your motor is stock there is nothing you can add to premium pump fuel that will increase performance. Nothing.
If you make mechanical changes to your motor,,,, cams, compression,timing...... you can increase HP/TQ, but the motor will likely require a higher octane fuel to allow it to run with out pre ignition,,, pinging.
