...one of the hottest debates in the game and most people have their own variations that work for them. Some of the common denominators between most everyone's plan are:
* to use additional mix-oil during break-in
* heat cycle the engine, allowing it to heat up and cool down in increasing time intervals
* not to put excessive strain or load on the engine for a specified time while increasing the load put upon the engine during the break-in period
What we do:
* mix 16 oz (475 ml) mix-oil with 4 gallons of gas, resulting in 32:1 ratio
* heat cycles of warm up, easy 5 minute run, easy 10 minute run, easy 20 minute run with cool downs in between
* burn the rest of the four gallons going very easy on the throttle, avoiding steep inclines, etc.
* mix 16 oz mix-oil with 5 gallons of gas, resulting in a 40:1 ratio
* replace old spark plug with new spark plug
* take it easy on the engine while slowly adding increasing load to it as the first tank of 40:1 progresses
* start checking for small jetting alterations that may be needed
* pay attention for air leaks, coolant leaks, etc
* after everything seems kosher, start enjoying the bike remembering to ALWAYS warm it up thoroughly
