Hey guys brand new to the site, I have a 2014 night rod special and have noticed metal shavings on the oil drain plug. I got the bike at 5k miles and done a oil change at 7k miles and noticed no metal shavings on the drain plug, now the bike is at 9k miles and I’ve noticed metal shavings on the drain plug. I ride the bike hard and do wheelies on it I’m just wondering is this to be expected since the gearbox/engine share the same oil? I’ll attach some picture hopefully they come through clear enough. Cheers in advance!
