If it extends engine life than how come when you run it on the dyno it has great HP gains on the first run and than it starts to drop after that? What % nitro are you using 10% 15% 20% hell it even goes up to 40%! Different nitro fuels are made for a reason, now if YOU want to run it hey by all means go for it but I like to know that my bike will start the next time I want to ride!
