Has anyone else had a similar issue and if so, what part(s) caused the problem. Thanks.
Not a similar mechanical problem, but a similar OEM Motorcycle company shafting an owner due to their poor quality verifications. I had a brand new 1997 BMW F650 ST, and it was using oil bad(!) I was putting in a third of a quart per 100 miles. The dealer said, "Oh, it's just breaking in" (my ass!) I rode like this for 2000 miles until I dropped it off and said, "FIX IT!"
Come to find out, it had no rings put in it from the factory (Austria)!! BMW from the Motherland (Germany) sent a complete sealed top end assembly with heads, pistons, and cylinders. Of course I'm thinking about the bottom end with that much metal grinding going on, but I was just glad not to carry 3 quarts of oil around with me and ride my motorcycle.
ANYWAY, in your case, IT'S NOT YOUR fault they don't know why they had a assembly error/vendor part's defect. That's not YOUR problem, their defect could have killed you on the road. YOU WANT IT FIXED NOW (a total new engine if possible)! They will keep jacking you around if you let them, believe me
