I just installed a two brothers slip on and while I was in there I gutted my cat. Sounds excellent now.
Problem I'm having is that the idle is crap now. Its super lopey and rough. I can get it to smooth out if I raise the idle to like 1450-1500 rpm, but then the revs don't drop as quick as I'd like after revving.
Right now I'm running a map I found on sportbikes.net (getting it tuned soon). I find if I lean out the idle mixture quite a bit (from +15 to -5) I can get it to idle steady occasionally, but revving it usually breaks this steadyness and sends it back to being rough.
Covering half the exit of the mufflers stabilizes the idle completely, so this is clearly an issue of the exhaust being too straight through for good flow at idle.
Anyone else experienced this issue with a similar setup? If so, what was your remedy (or did you just leave it)?
