I know on m cycles T4 for the wet clutch and gears but a 10w40 or 50. Being a big bore single it is a bit noisy and wonder if a 50 would be quieter?
The manufacturer recommends 40 but shell says 10w50
It all has to do with mileage, if your engine has high mileage, then you can comfortably go to a 50, as the thicker oil will take up the extra clearance between the worn parts.
You can even add a thick additive or as the "Old Toppies" did it with and old worn out motor, is add gearbox oil and help the motor do an extra 100 000 Km more then it would have done before bearing knock.
Thats how they got the beetle motors to run perfect with a hell of a play in the crank movement.
