I had major issues with Delkevic also, pipes just would not fit,
looked as if the jig was wrong and after the second set was even worse than the first set, the so called manager had to cheek to say I did not know how to fit them, when it was clear the problem was with their jig allignment. With the whole lot together it was 25mm away from the frame mounting bolt hole. He was lucky he was on the end of an email and accross the Irish sea.
Bought two set of Motads one for my son and second one for my own fazer and had no problem, great to deal with, such a shame they closed.
