…feed that journal with premix…50/1 verses 16/1 on a plain bearing….not my motor…roller elements 50/1 is fine. With a high silicon piston skirt 50/1 is okay when things are perfect. Early pistons were soft and need 16/1.
I understand the gas flashes off leaving the oil film. 50/1 is not enough oil for a non-pressure fed plain bearing. 50/1 was a boardroom decision for sales. The newer crowd sees an oil cloud they assume the motor is worn out like a 4 stroke.
The very first week of getting my 4 year in mechanical the prof says any product that lasts too long is a product failure…and products are designed to make investors money but that’s another issue..
