Don't let the excitement of your new purchase
overwhelm your good sense. A new pit bike must be broken in correctly if
you want the bike to function correctly. If you do not take the proper
steps, you will dramatically decrease your engine's life and possibly kill
Change your motor oil before and after break in. You
can use standard 4 stroke 10w-40 motorcycle oil (non synthetic & no
car oil & do not run it with the oil that comes in it).
Opinions vary significantly on the correct
way to break in a bike. We will discuss the most common method often
called "heat cycling."
Heat cycling means you run the engine at low idle for approximately 5 to 10 minutes. After this time the
engine will be right below the normal operating temperature. Then you turn
the engine off and let the bike cool down. Once the engine is cool, you
turn the bike on for another 10 minutes and then shut it down again. Do
this process for a total of three to four times. DO NOT put the bike in
gear during the "heat cycling" process!!
When you have finished this process, run the bike at
an easy pace, shifting thru each gear, during the 1st full tank of gas
at 10-15 minute intervals. Again, let the motor fully cool down after each
interval. After the first tank of gas you should change the oil for the
Avoid putting excess stress on the engine and avoid high RPM's for the
first 4-8 hours of run time.
Make regular oil changes from this point on (every 20-30 hours or every 3
months, whichever comes first).
