05 AIS and Exhaust

I haven't taken the AIS off my bike and I still have the stock muffler with the tip out and my question is: Do these things make the bike more finicky when it comes to jetting. The bike NEVER runs the same unless you compare it to a day when the weather was exactly the same. I understand that jetting is major but there should be a decent " all around " area you can hit and in my mind the AIS and non-straight through muffler might cause some problems. Would someone who knows about this please enlighten me or point me in the right direction. Thanks

The AIS will mask jetting problems, because you won't be able to tell if it's popping due to lean jets or the AIS. The pipe is also so convoluted due to the baffling that it will also create a jetting nightmare. The only thing I change on my bike now is the needle. Red 4/5 for hot weather, Blue 3 for cold. Everything else stays the same unless I change elevations, which almost never...SC

Thank you. Thats what I was thinking. My wife's 450R quad has the same problem just not as bad. It still has the stock muffler which is exactly the same as mine with the HRC end piece. You never really know how its going to run. I'm starting on the bike as soon as the money starts coming in again(spring). This is the ONLY place that I can ask a question like this and get a good answer. I'm sure there will be more.
