Hello guys. I have two z”s and i bouth have new valves, timing chain , piston and for one of it i replaced also the cilinder. In one word “fresh new motors”. Now i don”t know what i need to to for a long life motor. I hear someting like: heat up the motor, let it cool for 5-7 time. Ride 5h at 50% power. Change oil and ride it in normal condition. What its the best practice ?
