The manual says my ATV has a 20 hour break in period.  How do I determine how much time the engine has been running? 

[2015 Z Force 800 53/Trail EPS]

Got a watch? If not use the one in the pod. Just write down the times per day you rid it. When it totals 20 hours, she's broke in.

I trail ride mostly. If I loose track, I average 20mph so at that rate I am good at 400miles or 2-3 trips. I know not by the numbers, but close enough for me.

Personally, I heat sink it a few times and then pin it to win it. Just how I am tho... Although the Uforce in by the book.
