The way Saxton told me to break in was, Heat the motor to 200 with the heat gun. Then idle 4 tanks, keeping the temp around 200. Make sure the let the engine fully cool down between tanks, and use the heat gun to warm up each time. When the tank is empty, make sure the piston is Bottom dead center.

Once you have the 4 tanks idled, run 2 tanks on the ground, with a max of half throttle pull, again, heat gun before starting, and piston on the bottom.

After the 6 tanks, you can start to race tune, but leave it on the richer end for the first gallon. I use the heat gun on my engine for the first gallon. After that, you will notice you can lean the motor a little more.

Be ready, this motor will feel slow when you are on the track alone, but when you are around other cars, you can see how fast it really is. The power band is super smooth, hence why some say it lack top end. It really doesnt, its just so smooth, its not like the typical motor that either is idling or running like a bat out of hell. This is great because it lessens wheel spin, and helps fuel economy. I will stand by this motor, as i just received my 2nd motor for my truggy friday, and will be starting break in monday.
