Hey brothers. I've got a 2012 classic SE and have done the stage 2 debaffle.
I've been considering some performance upgrades but not sure where to start. I've looked at the Cobra Powerflo air intake and a KN high flow air filter but not sure if I add one or both of these if I will need a PCV or some other air fuel ratio mapping device.

Am I on the right track or what performance based mods does anyone recommend? Just put smog block offs, KN air, and PCV on my 2012 zx6 and it made it such an insanely hard pulling machine, just hoping to do something similar with the Vulcan.

Upgrades

I did pipes and intake on my 2008 custom, and that made a huge difference. I am not running an aftermarket EFI controller right now and the bike still runs fine, but we are at a bit of an altitude here. Most everyone else in the forum has some sort of controller once they do both mods.

From what I've gathered if you do pipes only then you do not need a fuel upgrade. If you do an intake and pipes then you need a fuel upgrade.

In order to get meaningful gains you need to do all three. DANAD, you say it runs fine, but have you pulled the plugs? You could be running lean, even at your altitude (as these bikes are pretty lean from the factory)

You can do pipes and intake, but you won't have any extra fuel; so no more power.

You can do pipes and processor, but there won't be any more air because of a restrictive intake.

You can do intake and processor, but there still won't be any more air because the restrictive stock exhaust and cats won't allow exhaust gases to escape, thus there will be no room for all the new air!

Alone or two at a time you can get mild gains, but it all comes together (and runs right!) when you have all three. If you are really serious about wanting your bike to run well and perform the best it possibly can, pony up and take it to a Dyno. Every bike is difference, guesswork (using maps for similarly configured 900's) can get you in the ballpark but if you want it to really pull, get it on a Dyno.

Folks who have done 'the big three' AND got it on a Dyno, have reported some pretty incredibly gains, some getting close to 100hp I've heard.

LA Choppers xXx Big Air Kit love this kit and cheap price! I also have Cobra Fi2000R PowerPro Tuner (Auto Tune) It plug and play no set up love this mod to! and with the secondary butterfly remove ( make a search about this a lot of good info on this forum !!) with those you will have some good gain!!

I don't ride the 900 as much as I ride my V2K, and I rarely leave town on long rides when I do ride it so the FI was not a priority. As I said earlier, the bike appears to run stronger than with factory restrictions here so I didn't worry about it. I am interested in the Autotune though and if it works on 9's with BAK and cobra 2 to 1 pipes I will try it.

Unless you use a fuel programmer it WILL run stronger with the factory restrictions. It's just a simple mapped fuel injection system, it's not like your car- it doesn't adjust itself for the conditions. So it's dumping the exact same amount of fuel even if you are running a high flow intake and exhaust; meaning it's now running super lean and losing power! Add a fuel processor to dump more fuel, and you're golden!

I agree with Romans on doing all 3, I have the Ness big sucker with a kn air filter noticeable performance difference between stock and doing all 3 performance mods I live in west texas

while that statement is mostly correct , it is quite possible that his bike is not running any leaner than a stock bike would be at sea level....remember he is at about 7000ft elevation.....just that big of a change in elevation would put a stock bike on the rich side......remember these bikes don't have a means to adjust for altitude either .....and factory mapped to run at sea level...

High riding

So I went on a few websites to check how much difference altitude will make to a non-sensing EFI system. For my area, in which the altitude varies from a low of 2100ft to a high of 6000ish ft, there is a difference of 10 to 14% in oxygen density from sea level. This is probably why the V&H Fuel Pak controller (now removed) wouldn't work properly on my V2K as you need a laptop to change the settings on it. I pulled the plugs on my 900 and there is evidence of lean burning though the exhaust residue would indicate that it was running rich (only use regular fuel so no afterburn in exhaust). Regardless, I will probably put the AutoTune controller in now that I have heard that it works (at least when close to sea level....) As for the V2K, even with the Baron BAK and the V&H pipes, it produces black smoke like a diesel if I roll real hard on it. I would highly doubt that it is running skinny but if there is an autotune to fit it, maybe I'll try one there too. Never enough power.....:cool:
