[QUOTE="davidd, post: 46084, member: 1177"] Craig, While I have a great interest in what you are looking for, I am not sure that you will find a satisfactory answer on this forum. I have suggested that there might be tangible benefits from dyno tuning for street bikes quite a while, but I have not heard of any owner doing so. I am also cognizant of the reason why- it is costly and a pain, so I am not surprised at the resistance. All my work has been done with racers on race fuel, so they are of little use to the average rider. However, I am not certain that any testing other than your own will be of any use to you. I have only tested modern pump fuel twice in the last four years and the tests were done with over the counter products to determine the amount of alcohol. Both tests showed less than 5% alcohol. So, I do not believe that there is anywhere near the alcohol in the fuel that there could be. I suppose this is bad news because if this small percentage creates as many problems as we have all experienced, I would definitely fear a 300% increase. Let's hope that all the bad stuff happens with just a small amount and the effects plateau after that. I do not think that you will find an owner who tested the fuel prior to dyno testing that will support the fuel ratio that you may be using. I am hoping that someone may have done so. David [/QUOTE]
