I recently purchased a 2007 F650GS. In the manual that came with it I noticed it stated NOT to use synthetic oil.
Is this really true? What are the implications of using synthetic oil?
I have a '71 R75/5 and mix regular with synthetic in that one.
I hope someone has a definitive, technical answer.
Thanks.
Dave
