Ok I’m changing the exhaust on my 2007 VTX1300C to fit the style of bags that I want. Im rejetting the carb. Do I also need to change the air intake, just change The filter or decamp the air box and change the filter. Leaning towards just going with the Baron Custom Accessories Big Air Kit, mostly for the look.

Any advice is appreciated.

You do not NEED to rejet or touch the carb when you change the exhaust (you may want to, since from the factory it runs lean). You HAVE to if you touch the airbox. I changed airbox mine and had my bike dyno tuned. If you do change the airbox and rejet, ONLY use the Factory Pro Kit (you can get extra jets at www.jetsareus.com, but you need the Factory Pro Needle).

Here is my tune and dyno numbers:

It's not a bad idea to properly tune the carburetor when making any changes to the airflow through the engine. I emphasize properly. It is a science but if you are armed with good information and tools and an open mind, you can accomplish anything that you need to. Motorcycles are lean from the factory because of the EPA 'mandates' (an evil word these days) so even tuning a stock set-up can improve rideability. Some people think that because these bikes are liquid cooled that it's not harmful to be on the lean side, but that is just not the case. Lean causes heat in areas of the combustion chamber that liquid cooling cannot help out but adding fuel will help and, more importantly IMHO, affect longevity of the engine in a positive way. More power is a great side effect of proper tuning as well. Who doesn't want more power for just a few $$ more without changing any expensive parts in the engine? These bikes have a lot of bang for the bucks we shelled out and that is just awesome. I have fuel injection on my 1800 so it's a tad different for my tuning but the result is the same on how it helps the engine. Look around on this forum and you will find a plethora of info to help you in deciding on changes that you want to make. Good luck and post your results so we all can learn from it.

While doing this work, also install Glen's permanent A/F screw and do the pair mod using dimpled block off plates. Also install a high flow reusable air filter like a K&N. Tuning instructions can be found here on the Cafe in the thread titled something like, "Carb - what affects what".

Thanks all, I appreciate the advice. I got the Factory Pro Kit, Glens screw and the Big Air Kit. Just need new headlight and driver and passenger floorboards and I'm all done.

Get the VTX Daymaker (NOT Harley-Davidson) LED. Several makes of floorboards still available, Rivco, Cobra, Kuryaykn, maybe 1 or 2 other brands.

Well as a reminder, my bike wasn't running poorly. I'm changing my exhaust to accommodate a specific style of bags. And I figured since I was changing my exhaust and I was going to be right there I could change the air intake and reset the carb. I don't need the upgrade, but I do like the style it adds.

I've got the new Vance and Hines pipes in as well as the Factory Pro Jet kit. They threw in the long screw, tho it's not s long as Glen's but it was free so I won't complain. I'd planned to get Big Air intake but went with the Cobra instead cause I liked the look more. The Cobra air intake will be here by Friday.

The floorboards (Kuryakn ISOs) and matching grips will be here by Friday. So I'll get started on the mechanicals Friday and then take her for paint and mounting the bags Tuesday. I'm still searching for a way to extend the passenger footpads/floorboards out past the new side covers that come with the bags as well as trying to find some lights I like for the rear bags as the LEDs that came with don't seem like nearly enough but I'm pretty close to just being able to ride in a few months when the weather turns. The passenger floorboard thing is only semi important because my partner will ride with me but she isn't enthused about the idea. And 99% of my riding is just me alone, so its not like I need to be able to give a buddy a ride if he breaks down. I just feel like it would be a shame to lose the ability to two up so I'm hoping my body guy can fabricate something to get my past this.

Oh and technically I'll probably ride a little before the spring/summer, I live in Alabama and there are always a few days a month when you can ride. I'll check in next week or the week after with an update and pics once its all good.

When you install the new grips, do not install the throttle grip sleeve too tight to the end of the bar or it can bind.

Vinish, the grips I got just go right over the existing sleeve. I also got a throttle lock that I'm going to order today or tomorrow so I'm going to change the crips and add the throttle lock all in one go. And I'm toying with the idea of changing the mirrors, I'd like to get them out to the end of the bars to get a little more vision.
