I agree, mine sounds nut'n like that. Could it be the dyno? ???Devious2xs said:EWwwwwwwwwwwww.
Not a good sound.
Is this why I notice the bike sputtering in first under 4000 rpm....I just noticed that it is beggining to do this more often.....anything higher than 4000 rpm and the bike screams.....Still thinking of that power commander...Devious2xs said:The problem is that the short tuned length of the Zard silencer wants less fuel at low rpm. We are finding that the tunes that work fine with systems using longer midpipes, need to be leaned down under 4600 rpm to improve performance and starting with the Zard silencer.
There have been several discussions about the issue on this site.
Let us know the outcome of the "dyno war", and post any graphs if possible.
