Race gas

[KDXFreestyle]

If I use race gas for 1 race, this weekend, do I run it 50/50 (100 octane) with regular gas? I have a RK Plug, 2003 Stock KDX (airbox mod) do I have to change my jetting? and what should the premix be? I believe I am running 40 something to 1. thanks!!

If you aren't going to tune specifically for race fuel then there is no point in using it on your KDX. generic race fuel does NOT give you more power.

There are at least 100 different threads on race fuel that will explain all this in excrutiating detail. Take a look around.
Until the search function is fixed here are a couple of threads that might help:
