Guys, it seems that my K9 has blown the crankshaft with only 5600 miles on it, the bike is 2011 and it is no longer under warranty.
See the sequence of what happened:
1 - Bike was running around 140 mph;
2 - Engine started to vibrate like a mono-cylinder engine;
3 - I saw the temp on the panel increasing from 181 F to 194 F;
4 - Engine started to lose power;
5 - Engine stalled.
No oil leaking and no smoke at all.
Everything above happened in less than 10 seconds, I didn't even have time to think about anything.
Then I parked the bike on the road and tried to start the engine again... the engine didn't even turn.
I Took the bike to the dealer and he found the battery was not being charged, so he swapped the battery and the engine started apparently with no issues, however when he pumps the throttle a little noise comes from the engine and we feel the engine vibrating.
The dealer has not opened the engine yet, but since the battery was not charging we are thinking that the crankshaft is broken at the stator side.
I have read other people complaining about crankshaft issues on K9, see below:
My question is if the problem is really the K9 crankshaft, even if I get it replaced by another K9 crankshaft, the problem still can happen again. So does anybody know if I can replace the K9 crankshaft with the L2 crankshaft (which seems to have the root cause of the problem fixed)? Did anyone have a similar issue?
Their PN's are similar, but not the same:
12000-47850 K9 Crankshaft
12000-47860 L2 Crankshaft
