Just about to do the 3rd oil change and debating on switching to synthetic. To be clear, I will only ever use the Honda branded oils as I know the spec will be a perfect match for the machine (and yes I know Honda doesn't make oil). So my debate is whether to go with the Honda synthetic or stay with the HP4. I thought I saw something about they will burn a bit of oil if you go with synthetic. As we all know, the bike shifts a bit smoother right after an fresh oil change. So that's why I am debating synthetic as maybe it will keep the smooth shifting longer. Thoughts?
