Because the new main input shaft comes from the factory with a "facing" (I think that's the right term) on it, one must not exceed 40 mph during the first 2500 kilometers of usage.
This "facing" will be worn off by the action of the gears in the gearbox and float about in the 20W50 oil that is used within the gearbox.
Gearbox oil after almost 500 kilometers of usage.
As you can see, the oil is quite dirty and the metallic particles are visible floating within it. There should be, hopefully, much less when I do this oil change again in about 1000 kilometers.
Hopefully also, the oil will come out looking more golden brown than black as well!
Just takes a while, at 40 mph max speed, to rack up what will be a total of 2500 kilometers (1500 miles) of break in period riding.

The break in period is my least favorite part of motorcycling. A necessary evil as it were, but 2,500 km seems like a lot.....especially at 40 mph. Happy for you that it going well!
Thanks, AZ HD, nothing has blown up so far.... :)
"nothing has blown up so far...."
Such optimism... 2500km does seem like a lot. Even the new rigs don't have that long of a breakin period.
RichardM, yeah it seems like a lot. There's even a sticker on the tank detailing breaking in speed limits and it shows 2500 km. I think Bural said I could stop at 2000 km but what the heck, might as well go the distance if it'll result in a properly broken in gearbox.
