ok so i was at my freinds race on his apex and i noticed that he was taping something so i looked and asked him, if you put electrical tape(no other types of tape!) around your axle nuts next to the swingarm around them a couple times if you look down one day and the tape is split your nuts are loose. I wasnt sure but i tried it and one day the tape split and sure enough when i took it off i could spin the nut with my hand. And this can help preventative maintenence on damaging you're axle and swingarm and saving you a lot of money. Simply look down at them when you are cleaning you're bike real quick get in the habit of it and I just saved you alot of money!
