Howdo! Wonder if anyone has fitted low level Spark exhausts to a carby Monster? Just got myself an abused M900 (1999) and a set of 2nd hand oval lowl level Spark exhausts. On installation the nuts holding the Spark bracket is tight to the swingarm. I have measured the Monster headers and they are narrower than on my SS? 11inch compared to 12. Any advice???? Cheers Pablo
