Bike purchased from original owner last spring, and have put 2500 miles on it. Owner had been using regular BMW 20w-50, but I've considered going to synthetic.
I read somewhere that it might not be advisable to do so until the 'break-in' period has ended. Bike is now 15 years old, but very lightly used.
Am I over-thinking this decision? Or should I just go synthetic and not worry? Lots of garage time to think about all these weighty decisions.
