1) Make sure the oil injection is ready to go. (properly bleed)
2) Put a little oil down each carb. (1/2~1 oz)
3) Put oil in the fuel tank. (you need to run extra oil for the first tank)
4) Put it in a lake
5) Start it on the trailer, and check for leaks, and set the idle.
6) if that is good.... then go enjoy it. A few full throttle blasts is good for break it. Basically, don't abuse... and don't baby it either. AND... DO NOT let it stay at one RPM for a long time.
