Question for the racers

[Diabolus]

For those running racing events, what fuels do you generally run?
Regular pump gas, racing gas, or maybe a combination?

It race gas a waste of money in these small engines?

Thanks in advance!"

Unless you are running 12.5 to 1 comp ratio or higher you are wasting your time with the race fuel .
What comp ratio are you at ?

My drag bike I run 110 turbo blue, motor 14:1 compression. Most of my other motors I've recently started running 100% gasoline (no ethanol or alcohol) these motors are all around 12+:1.

Well for now, when the bike is done, I'm just gonna run an old flat head when used as my pit bike. In the future, I'd like to build something fast for a couple of races here in the Detroit area.
Just trying to get some ideas of what people are doing these days, I've been out of the sport for over 30 years.

Thanks for the info, I appreciate it!
