@dave I'm in San Diego.
There are 2 things that need timed in this engine.
The camshaft needs to be timed when you replace anything related to the camshaft or cam chain. This would have been done when they replaced the cam chain and guides......you said the engine has compression and turns over fine - so I believe the cam timing is likely fine as it ran for a year after they worked on it.
The balance shaft needs to be timed if the center case was split and the balance shaft and/or crankshaft was removed. There is no reason for the shop to have split the center case into the left and right halves to replace the cam chain or chain guides.
Something went wrong, and at this point I don't believe it was the shop screwing up the timing......if they did I can't see why it would have taken a year for the collision between the rod and balance shaft.
This photo shows a nice even "squeeze" of sealer oozed out of the crank halves, and I believe this is the original factory applied sealant, as getting the sealer this even by hand would be difficult.
