Factor,

Based upon the pictures of the connecting rod big and small ends, I would suggest a failure of the oil circuit to get oil pumped through the crank and out of the crank pin onto the big end bearing and of the spray circuit to spray on the oil hole drilled in the small end of the rod. See page 53 of the owners manual for the oil circuit.

This could be caused by several things.

Absence of or failure of the small oil seal in the left side case cover for the end of the crank shaft could cause the damage to both ends of the connecting rod and the balancer..

Installing the connecting rod backwards would put the rod small end oil hole on the wrong side of the engine so the spray would not direct on the hole.

Plugging of the oil pump circuit.

Improper alignment of the crank pin oil feed hole relative to the crank cheek oil drilling.

Regards,

Joe

Wear pattern is typical of an engine which has been lugged excessively and / or detonating.

Note the heavy spalling on the load side yet lack of discoloration.

Dale that is what the Mechanic/Engineer that is doing my engine told me. He also said that the crank was spread at the bottom indicating that as well.

He said it was time I changed my riding style... i tried to do everything right to the big girl but it seems i didnt ride it right

(would have thought it would cope with my riding style but i guess this indicates it dont)
