don't side step the clutch, but use the entire rpm range. The same bearings and crank are in the 16v gasser that revs almost 2x what ours do due to the pump gov. Every engine I have ever seen broken in not using the full rpm range had oil consumption issues if you ever went over that break in rpm. All the racing atv's I used to have the engine guy would say "so many hours then you can use the full rpm" Later when he sponsored me he said "I only say that to people to buy time and if there is an issue I can say they ran it too hard, in reality if I did something wrong it will show up no matter what they do, just run it"
You want to use the entire rpm, but not like a drag race. Take it up a bit, hold a second, take it up more, hold a second, etc, for the first drive to get to redline, you don't want to knock the temper out of the rings. Then use the full rpm range for a while but don't do the .15 seconds for the pedal to be on the floor, take like 10 to 15 seconds or whatever, don't just run the piss out of it use the full rpm range but gently. Get some miles on it and run it like normal. I tend for overkill so I do 500-1,000 before I run it completely normal, after 100 it is probably fine.
