First of all, whoever did the dyno runs are compete idiots because in order to get correct numbers you should be doing a fifth gear roll on and not a fourth gear roll on. Second, motorcyles are designed to be run on higher octane fuel regardless of what the manual says because of their higher compression ratio. Runnig a higher octain will not hurt the motor, higher horepower numbers can actually be achieved by just running better fuel alone. I cant think of the company but there is a company that sells 118 octane fuel that will increase power by 3%. Do to the price of it ($11 a gallon) I wouldn't recommend it but this is just an example of how higher octane fuel can increase horsepower and efficiency in a motorcycle. Last but not least, when doing modifications to your motor a carbs make shure to do things one step or setting at a time. Going ***** out on your settings will not allow you to see what correct setting on those aftermarket parts is right for your bike. Just cause the jets have 5 settings doesnt mean that your bike will run bettier on the highest setting.
