Concerning rebuilding a 99YZ400 motor

2 posts in this topic

Let me first apologize for not looking up this in the owner's manual, as I'm overseas and will be home in two weeks. Just trying to get a head start on some thoughts about refreshening the engine.

My question is, if I am wanting to rebuild the motor to include pulling the head, replacing the piston and rings, and the rod and associated bearings, can I replace the crank pin and rod without splitting the cases? I really don't want to split them, but my WR motor blew because of a split rod.

Thanks in advance!!
