Fuel additive
Having my own race bike I think I am qualified to talk on this subject. You see we run racing fuel or fuel additives in the race bike. On street bikes alot of guy's run additives or racing fuel cause they FEEL that they are getting more H.P. This is not true. Only run an additive or racing fuel to stop a detonation problem. As soon as you start to run an additive or racing fuel to your bike you have just changed the specific gravity (weight) of the fuel. And guess what, this means that the engine is now burning leaner or richer and now you have to tune for this combo. Racing fuels have a specific gravity between .66 and .74. Racing fuels burn faster, so now you have to feed more to the engine. Also different additives and fuels require igition advance changes for optimum power because of the way the fuel burns. And remember this, an excess octane level is not helpful, due to the way it burns in your engine. If your timing and advance curve is not on the spot and you are pushing to much octane for your engine combo you are not gaining a thing. In my opinion unless you have to run an additive in your fuel for your engine, stay with preminum pump gas.
