Dont use the clutch alot, i must admit the bike is pretty much vertical when i am out on it. But I doubt that would cause it to damage the box due to no oil. I am pretty sure its going to be the same as last time, stripped a couple of teeth from second gear. So maybe pinging it up in second is doing it. Dunno, just severly pissed off i have managed to do another and i have only done a couple of thousand miles on it.
