I am interested too. What my mechanic did few days ago was putting SAE 20. When he told me what he did I thought the bike would ride like crap, but it doesn't feel bad, specially for being on winter. I have to ride it harder yet to be sure. SAE 10 was not good on summer fast rides in Spain, but maybe the way to go is SAE 15.
