4B11 break-in
I have to flip through the manual to see if it's covered (I doubt it will be, but I've been wrong before), but does anyone know the 
-recommended break-in for the 4B11 motor? I only have 200 miles on mine and it occurred to me today that I should probably find out before I ruin the motor...
EDIT - Manual info
Page 3-2
Advanced automobile manufacturing techniques permit you to operate your new vehicle without requiring a long break-in period of low-speed driving.
However, you can add to the future performance and economy of your vehicle by observing the following precautions during the first 300 miles (500 km).
Drive your vehicle at moderate speeds during the break-in period.
- Avoid revving the engine.
- Avoid rough driving such as fast starts, sudden acceleration, prolonged high-speed driving and sudden braking. These would have a detrimental effect on the engine and also cause increased fuel and oil consumption, which could result in malfunction of the engine components. Be particularly careful to avoid full acceleration while in low gear.
- Do not overload the vehicle. Observe seating capacity.
- Do not use this vehicle for trailer towing.

There are two methods : the hard break-in and the easy break-in. Supposedly the hard will allow the rings to seat better again the bore walls. But people have different opinions of each.

Well on my 2007 Yamaha R6 the manual said not to go above 6k rpm for extended amount of time. After 200 miles don't go over 10k rpm for extended amount of time. Then after 1,000 miles you can go how ever rpm you want basically up to 16,000 rpm.

Well, I can't say I've treated my engine perfectly, but it'll be broken in after the couple trips I have planned tomorrow. Hopefully I didn't **** anything up too bad...

I'm sure you have nothing to worry about. It's not like you're absolutely torturing your engine. So what if you didn't baby it? If a motor is completely f'ed after a little hard breaking in (it's not like you tracked it or took it autocrossing), then that's complete crap. Does any company make a motor that can't hold up to a little abuse?
