R1 and R6 is completely different engines...... And they did have a problem , but not saying it was a recall but did have a issue....Most likely the other owner either beat the shit out of it , and maybe rode it so rough it was starving for oil , or drained the oil and rode with no oil, what ever the case is.....What is done is done nothing he can do but fix it....Making calls is not going to get his bike fixed....
