They use the same Rod Kit #13044-5073 / fits 1988-2015, same RH bearing. They don't sell a LH bearing, cause most can change it.
The 2011 screen doesn't show the Left and Right main shaft individual part #'s. Just a complete crank or a rod kit.
I think they changed the paint color on crankcase again, so different part #. Probably just to keep us all confused!
I see 2 different spacers, outboard of the RH bearing.
92026-1280 (30x50x4) '08-'10 / 92026-0150 (no descript) '11-'15
I see 2 different 'claw' washers, under the RH nut.
92200-1157 '08-'10 / 92200-0557 '11-'15
I'd guess a vendor change for the spacer and claw washer.
If I was buying a used part, I'd suggest interchangeable.
If I was needing a crank for my 1987 -A1, I'd have to risk it. They don't supposedly sell a crank to fit the 1987 -A1. Sold Out / No Longer Available / No Superseded Part #!!!! But they all (1987-2015) use the same bottom rod pin or superseded Rod Kit #.
