I got to talk to the service mgr/mechanic today on the KS.
It appears the cam tensioner might be an issue. I had the cam chain/tensioner replaced around 35-40k miles if I recall, it was noisy at the time. Pistons are real close to the valves so there isn't a lot of room for slack/error.
I think it has something to do with the 12k mile+ tensioner versus the early tensioner, even though the timing chain broke when the engine locked up. Some pretty good dents in one piston, which they won't replace but claim it won't cause problems.
He has to figure it out first to report to BMW before they pay for the repairs, then hope he finds everything that is no good the first time so they don't need to do a repeat. Lots of mandatory replacement parts on this engine (one time use).
top end needs rebuilt basically. They will not replace the head or engine.
it'll be a few weeks before its done hopefully, I told him not to rush, whats the point.
It will be 4 years I've owned the bike come Oct 2010. With this repair stint, I'm looking at near 6 months this bike has been in the shop (2 transmissions, final drive) for warranty repairs.
I just dunno if I can keep on going like this. I need my bike! I'm looking at used long rangers since I totaled my LT in Oct in the meantime. good grief. My karma is rippin me a new one lately! But I'm still alive and drinkin beer so my mantra still stands...LIFE IS GOOD...but beer is better!
