Oil is one of the most argued-about items in all of motorcycling. You're opening up a can of worms, infested with a nest of fire ants.
The only things I can say are:
- it seems that mechanics and racers commonly state that break-in occurs well within the first 1,000 miles, maybe even less, contrary to the old break-in myth patterns. Older technology in machining required the long break-ins for all surfaces, such as transmission gears et al, but the surface finishing quality of modern machinery is way above such levels. Even Popular Mechanics did an article about it, pretty much stating that long break-ins are a thing of the past.
- I have
always driven my vehicles from the first day as if I was using them every day. Very little, to no, break-in, maybe 200 to 500 miles tops. Then change the oil. I have NEVER had a
single vehicle (and all my cars were turbocharged) ever use a single drop of oil or suffered from a single mechanical failure due to oil-type problems (never, ever ever a spun bearing, low compression, low power, thrown rod, engine knock, seizure, etc etc).
Actually, my very first car, so long ago. was a dealer demo turbo and I could tell that it had too soft of a break-in because it shifted a valve seal, causing low compression. After they replaced the head I broke it in my way, drive it normally from almost the first day (OK, don't pound on it, but don't baby it either) and I never had another problem like that, ever again.
- I switched to Honda synthetic at my first oil change at 600 miles. My bike's tranny did not like it, pops out of 1st / stiff second. Switched to Rotella T6, loves is muchly, no problems whatsoever and does not burn or lose one single drop of oil (14.5 months old, 14,500 miles).
So YMMV and take it with a huge cupful of salt.
I would switch, I actually did myself with absolutely no problems.
