Well... one of the most subscribed motovloggers on Youtube has made a trademark of spending hours putting his gloves on at the beginning of almost every video of his.
RebelYell91.
The late Svengalie would often a/ not talk at all in a few of his videos and these weren't the shortest ones and b/ do many, many videos off bike and c/ breathe very, very, very heavily when crashing (often) or dirtbiking (even more often). And he, again, was one of the most subscribed motovloggers on YT.
Hell even Mordeth13 didn't have a decent HD camera up until a few years ago.
I don't think there are any rules to motovlogging.
I think the above mentioned rules are good for the bog-standard motovlogger to follow - they seriously are stuff that WILL put viewers off - but they will only get you to a certain point, and not much further. What makes the REAL difference is the rider's personality and his creativity with how he shows it.
To the question: "do I
actually want more?", the simple answer to that is that if you haven't got more already - you probably won't ever. And if you try too hard, you'll get caught a/buying subs b/buying views. Only the genuinely interesting guys get real community feedback. Not talking about views or subs. Community feedback.
