It's hard on anthing plastic or rubber. Like the tip of the float needle.
You also have to rejet to run race fuel. General rule of thumb is up two sizes on both pilot and main.
Most motorcycle engines and especially mini's, don't have high enough compression to run straight race fuel. You are just sending $ and HP out the tailpipe. Even though it runs better, you are wasting your $. 1/3 race gas to 87 pump gas is good. Or 50/50 as well. You will make more power and spend less money.
