I opted for 10W-40 full synthetic oil (Yacco 1000 MVX 4T) and a slightly taller but compatible oil filter (HF204).
Post-change, I've encountered a couple of issues:
* **Reduced Power:** There is a noticeable loss of torque, particularly, the sixth gear feels slower than the fifth.
* **White Smoke:** White smoke is appearing from the motorcycle, but it's not emanating from the exhaust.
M50TUB20 (Euro '94 320i) - I've been running Yacco VX600 5W-40 since I got it, I'm close to 6k miles
