I have a 2020 iron 1200 with only 6300 miles on it. I bought it the end of sep. Well before my first payment was due at around 900 miles it started making noise so I took it back to hb Harley , the found there was no oil in the primary. Well it burned the clutch they fixed ut. Then right before my second payment was due the engine locked up. Had broken sparkplugs and inch long slivers of metal in the oil. I've changed the oil 4 times within the 6300 miles but used Valvoline 20/50 motorcycle oil each time but they voided my warranty saying I used aftermarket oil. Well in my opinion no brandnew engine should have in. Long slivers of metal inside even if I never changed the oil. Just lookng for some comments from anyone on this.
