Hi COX, I have as yet not run the motor in, I bouhgt a run in bench from Serpent. You must remember that you MUST run the engin in with the fuel you will race the motor with, nothing else, and watch the temp. I would suggest you follow all the other recommendations of Novarossi, except for fuel. Remember that they need to make considerations for the people that live on farms and use tractor oil as oil in the fuel...
I use 16% nitro (nothing else is race legal here)
