Is this a a brand new bike?... use the oil it came with...
...or is this a rebuild?... Shell Rotella dino is fine...
Shell Rotella is fine for any engine that ain't running a cat... diesel or gas...
... and I'll run it in a cat...
I wouldn't use synth oil,... or any oil with friction modifiers, etc...
The most important thing during break-in, is that you don't go 3k miles on the original oil...
Some folks even change it out at 100 miles... 300, and 600, and 1k...
I'm not so picky...
I'd go maybe 300,... then 1k...
I'm lazy and cheap...
Don't do any WFO runs... or long highway cruises...
It's like breaking in new tires... be gentle to start... each additional mile you can allow more leeway, up to somewhere between 600 and 1k miles...
Then,... yer' good ta' go...
JMHO... no one does it same...
... it's just that first miles are seating the piston rings and other parts... You'll get some shrapnel in the oil filter, and that's normal...
After the first few hundred miles, the metal shavings die down, and the engine smooths out...
I even knew a few old timers that used to just get out on the highway, and push their cars up to 100mph for an hour or so to break them in...
Their cars always smoked, and only lasted 30k miles...
... but they had great faith in what they did...
... don't do that...
...
Ask 100 people,.. and you'll get 100 different answers...
Honestly,... I don't know why I'm answering your question...
Others can probably give better advice...
I have seen metal shavings come from new engines... and it's scary to look at, but normal... you just want to change out the filter and oil to remove them before you strain the engine too much...
That's the basics...
