Anybody have an extra rod they want to sell?
This could have been the result of multiple hydrolock incidents. (pics attached are of one I am sure had multiple incidents.)
Yours was no. 2 or 3 so its doable from the bottom with the engine still in the frame.
1 or 4 requires splitting cases to replace.
I have some K and L marked conrods, but you need to replace the conrod with one of the same weight.
There is a weight letter designation printed across one side of the original conrod and the crank connector.
See attached pics - if you can't make out the letter, look up into your crankcase and find it on the other conrods. I don't think the factory mixed and matched opposing pairs, but its possible to do so and still maintain the balance of your crank and pistons assembly. I learned this from SISF.
The plain bearings also have a colored weight indicator somewhere on the edges of the bearing halves where they meet, indicating the size matched to the crank at the mfg.
I re-used the existing plain bearing halves in the replacement conrod / connector combo, verifying clearance with plasti-gage before committing. It was in good condition and already seated into the crankshaft.
