I have a 2013 SG that I put cams in. After the install I have what feels like a miss from 2500 to 2800rpm. Not sure that the bike is running 100% at other rpm but it seems to be. The bike idles fine. The problem seemed to get worse after installing the dual exhaust. I've pulled the cam chest cover to re-check the timing and I readjusted the pushrods but it's only had a minimal effect. This is the stuff I've done to it in the last month or so in order of add-ons:
V&H naked air cleaner
V&H slip-ons
Power vision tuner from Fuel Moto
(note: at this point the bike ran perfectly)
Woods 555 cams, directional lifters, adjustable pushrods from Fuel Moto
V&H dual dresser head pipes
I received new maps along the way from Jamie and have run Autotune to try and fine tune things but this latest issue will not work itself out. Needless to say I've gotten a bit frustrated. I don't know what to do next. Hopefully one of you can shed a light on what my issue might be. Thanks in advance.
Have you tried adding any timing in the area of the stumble? Does auto tune do this for you or just adjust the air/fuel ratio? try adding 2-3deg of timing if that helps and a couple more when the gains start to feel like it's going in the other direction back of 2 deg.
I had to add 7deg of timing starting around 2500 rpms and my bike came alive with the T-Man 662-2 cams, I'm running the PCV (5)

Yes, I plan on calling Jamie on Monday. Already ran this by him last week prior to getting the new head pipe from him on Friday. Doing all of these upgrades is right at the edge of my skill level so sometimes I'm not sure what direction to go. That kind of why I wanted to throw it out here. Thanks for the input.

If you did all of those upgrades yourself, give yourself a pat on the back. Some people can't even change their own fluids....

I'm assuming you double checked your O2's were installed correctly with the duals? Ok, what do your VE's look like? Have you got a valley in that RPM range or maybe a peak? If they aren't smoothly climbing through that range, you may have some cam related reversion. Did you try some CDE adjustments to help them out?
I had this same problem after installing my Woods TW6-6 cams, my miss was very intermittent between 2500-2900 when rolling on the throttle. After talking to Brian a couple times at FM the decision was to add some timing like GaugeMods suggested. I ended up with a 2 degree add in that RPM range and haven't had a problem since.
