Following that logic, then they arent the right size, they are a bit too big ergo, its really not ducati whove made any design errors, as theirs fit the size they made... thats what i can gather from the above claims
That said, ive never heard of anyone having any of the stated problems, due to undersized engine bolts... im not debating wether or not they give any added stability, though i doubt it can be very significant, i just dont see a problem with the current set up...
