Perhaps we are arguing semantics here but I still think going round a corner with the clutch in is a bad mistake. To me it means you have lost control of the situation and are dangerously close to a crash. However, this is meant as constructive criticism, not a put down. God knows I made enough mistakes in those early days and you quickly learn from them. Congrats to jsan for posting them on here and getting feedback. It’s sure is quicker to learn from other peoples mistakes than your own, and potentially a lot less painful.
As you say, with the clutch in you will get that wobbly/jello feel that saps your confidence and makes the bike hard to control. Being on the gas ever so slightly will settle it down and it will feel planted, inspiring confidence for you to lean over and make the turn. Don’t want to get into the physics too much (mainly cause I don’t understand it) but I think it has more to do with getting the suspension working in the sweet spot than anything else.
