I think its 10 hours? 10 tanks of gas would take a long time. You have no way to tell how may miles you got on her unless you got one of those Speedometer things!

It really depends on how you break it in. I have always said two tanks as a rule but, depending on how you ride, it could take less/more time.

Ride easy for 15 mins. Let is completely cool down. Ride easy again for 15 minutes. Let is completely cool down again.

You are now broken in

:D

Yep, this is the correct method when you are only breaking in the cam and rings. Just make sure you DO NOT let the bike sit and idle for a period of time...that is very bad when breaking in a new cam.

I have always done 2 tanks of gas and then i change the oil. I then run 2 more tanks through and change the oil, adjust valves, and new spark plug.

I always considered mine broken in after 2 tanks. Dealers say to bring it in after about 10 hrs. to change oil and adjust valves.
