My dealer installed a ripsaw on my 03 and 120 1.325's down the middle. The track loosened up a bunch the 1st 1/2 hour of riding, racheted bad and tore off the heat shield. I've since tightened and no ratcheting and everything seems to be OK, no green snow but have not inspected heat exchanger. Two questions....1. Are you saying there is no chance for warranty if I did ruin my heat exchanger and 2. Are the heat shields needed? Thank-you.
