I took quite the high speed spill a few days ago with put me in the hospital, but im on crutches now.

Well anyways, besides the point, my bike freerevved out of controll after it came to a stop laying on its side, for idk maybe 5-10 seconds.

Well my brother in law checked the oil and coolant for me and took it for a spin and it locked up on him. It kicked over immediatly after but it was rough.

since im housebound for a while i cant get out to take it apart to see whats wrong. But I'm guessing a main bearing or big end rod bearing went. Is that what you think?

thanks in advance
