How to Properly Break in Your Engine
<ul>
<li>Lubricate everything very well when assembling.</li>
<li>2-stroke: add some extra oil to your gas tank 80:1 if oil-injected sled.</li>
<li>4-stroke: you must prime your oil system</li>
<li>1st fire-up is the most important! Let it sit and idle.</li>
<li>Do not go over 2k rpm.</li>
<li>Make sure your coolant is cycling.</li>
<li>Make sure the thermostat opens + 30 degrees.</li>
<li>Then shut it down.</li>
<li>Repeat the steps 4 times.</li>
<li>Run it in a break-in sequence, so we can seat the motor.</li>
<li>1st run Run it about 2 hours and no more than quarter to half throttle and 1000 rpm below your maximum (DON’T PIN IT).</li>
<li>2nd run 2-4 hours.</li>
<li>Do small WOTs (Wide Open Throttle) no more than 1 second of wot!</li>
<li>After 4 hours, change your oil (4-stroke only)</li>
<li>2-stroke After 4 hours, decrease the ratio to 100:1 until you hit 8 hours.</li>
<li>Make sure you let the sled get up to operating temperature.</li>
<li>Must have the Thermostat open up before you load on each ride for preventative maintenance.</li>
<li>If you start your sled cold and get on the throttle right away, it will create excessive stress and resistance on your motor.</li>
<li>Increasing the chance of a breakdown</li>
