1. Before starting the engine, fill the fuel
tank with the fuel.
2. Perform the pre-operation checks on the
3. Start and warm up the engine. Check the
idle speed, and check the operation of
the controls and the “ENGINE STOP”
button. Then, restart the engine and
check its operation within no more than 5
minutes after it is restarted.
4. Operate the machine in the lower gears
at moderate throttle openings for five to
5. Check how the engine runs when the
machine is ridden with the throttle 1/4 to
1/2 open (low to medium speed) for
about one hour.
6. Restart the engine and check the operation
of the machine throughout its entire
operating range. Restart the machine
and operate it for about 10 to 15 more
minutes. The machine will now be ready
The manual doesn't mention anything about "cool-down" periods. Should I let the bike cool down every 15-20 minutes of the first hour of riding? Is this necessary? When it says "lower" gears, do they mean 1st and 2nd?

Start the bike, let it idle for around 3 minutes then shut it down. Let it cool down, about 15 - 20 minutes. Do this proceedure 2 more times.
Use of lower gears doesn't matter. It's the RPMs that are critical. Don't over-rev your engine the first time out. You won't be able to do this if you haven't modified the throttle stop.
Your bike is ready to race.

You reinforced my comments. It's not the gear, it's the RPM. You can lub the beast in 1st or 2nd. It's riding at a moderate RPM that is important.
Like others have said 'It's race bike' let it lose.

Yes its a race engine, but when its first assembled the temps run considerably higher due to closer tolerances and the parts that hace been machined and forged need to rub smooth to reduce friction.
Dont be slack. do it properly, after all it only takes just over an hour.

I ride the new bike around for a few minutes and then dump the oil and filter. I change the oil, check the nuts and bolts and then I go riding.
Break in is bull schit in my not so humble opinion.
Stop wasting your time, go riding.
