X45 crank bearing smoked
My buddies 1200 took out the center cyl crank bearing. I havent gone over to take a look see yet but he says it bent the rod also. Any ideas off the top of your heads ? He said no obvious signs of water intrusion.
This may be the killer- its an SBT long block.

How about a leaking needle and seat? I've seen them fill the cylinder and then BAM hydro-lock.
Does it have oil injection or was it removed for pre-mix?
I hate to ask BUT did it have oil in the container if it's oil injected?
How about some picts?
Otherwise I'd say their crappy bearings tubed.............

yep. I would bet its the cheap bearing manufactuer they use ,and it let go.
ditto on the hydrolock.. oil , gas ect...the bent rod is what makes me think that also

The oil injection was my first question to him... he is premixing.
And the bent rod is strange. Good call on the carb. Worth checking out.
I will be going over this week to have a look see and will get some pics if we cant figure it out.
