m8 break in
As to break-in, most of it happens during the first 50 miles, where the piston honing and rings are setting in, so you want to take it easy on the engine during that time. Go through a heat cycle, and let the engine cool. Vary your RPM's, but don't exceed 3,000-3,500. Accelerate and use engine braking so the piston rings go through positive and negative pressure. After 50 miles, the rest of the moving parts continue to set in, like the sprockets, chains, gears, bearings, etc. Continue to vary your RPM's, but keep them below 4,000-4,500 until your first service. Generally speaking, after about 500 miles you're pretty much set.
All that initial wear has resulted in a lot of fine metal dust in your oil. Most of that will get trapped in the oil filter, and on the drain plug magnets, but it's still in the engine, so you don't push the engine to its limits during the first 1,000 miles. That's why the first fluid change is so early, and so important. You'll want to get that stuff out of the motor as early as possible. After that, your engine has broken in, all fluids have been replaced, all nuts and bolts checked, and you're good to go.
The MoCo says first service at 1,000 miles, because it's an easy number to remember, and it'll take most riders at least a month to hit that number. So you get to ride your bike for a good bit before you have to take it back to the dealer.
Me personally, I'll pick up the bike, do the 50 mile break in over 4-5 heat cycles in about 2-3 hours, and bring it back in for a quick oil change. That will get most of the metal filings out of the system. I'll ride the remaining 450 to 950 miles of the break in over the next week, and bring it back in for a complete service. After that just stick to the regular maintenance schedule. Bring it in at least once a year, or every 5,000 miles. While the oil won't go bad from just sitting there, other fluids will. DOT4 is hydrophilic, and needs replacing every two years, whether you ride it or not. Ethanol gas can separate if it sits too long, causing corrosion and/or clogging in the fuel system. Other parts may deteriorate more quickly if they're not lubricated regularly by the oiling system.
When you ride your bike, make sure it goes through a complete heat cycle. Don't hop on it to ride only 4 miles, and then put it back in the garage. This will cause moisture to build up in your engine and exhaust. Make sure you go easy on the engine until it's reached its operating temperature. Don't go doing wheelies or burnouts, or red lining it after you just started it.
