I've seen a couple people running aftermarket exhaust with a stock air cleaner with no tuner. Is this safe to do. I thought it was a Must have thing.

 

[SmokenJoe]

It's safe to do.

Second that... the exhaust doesn't change anything concerning how the engine runs, so no problem there. If/when you put a bigger air intake on your bike, then you will need a tuner.

Sweet thanks guys, I guess the salesmen was just trying to sell a little more haha.

I think that sell is a decent upgrade. I would be a valuable dyno to have someone get one with those mods and no tuner. All bikes are different, but it would give someone a reasonable idea of where one stood with those mods

I have only changed my Exhaust. Put on Cobra Sweeps. I love them and the sound is amazing. Nothing has changed with how she runs. I was told by the dealer mechanic that the factory fuel injuction would be able to cover just an exhaust change. Only need tuner if I proceed to change more, like the air intake.

I have the Big Radius with a K&N filter and she runs great with no tuner.

Perfectly safe. Sometimes you might burn a little more gas, but its so minimal, I wouldn't worry.

Been saying this for a while now. No tuner needed when pipes and filter are added. Bike is fuel injected and will compensate for differences.
Saved a bunch of money for more modes. 8)

yes sir i agree...heck i think the oem paper filter flows about as much as the K&N does. Now if i had a aftermarket air intake or even a modded airbox then yes i'd definitely need to look into some fuel management.

Bet you wouldn't. If you add one, run without tuning and give opinions. I'd be very curious to find out.

Guys have added pipes, open air boxes to their VTX's and when things don't run right, the suggestions for a fix is to disconnect the tuner and see if it goes away. Sometimes it fixes the problem and means a new or repair is needed.
This is JMHO.

I've always planned on running with out a Fuel management system, but with the Low and Mean steal on the Fuel Pak, I'll be running with that.

My bike ran fine with just the exhaust changed, but when I added an aftermarket air cleaner it was a no go. It sounded and ran fine when I first started it, but when it started to warm up it ran so lean it would stutter and pop unless I was hard on the throttle, and it even tried to die at idle. I noticed my pipes began to turn a slight yellowish tint straight out of the head under the heat shield as well, and they were bluish before. I rode it VERY little until my tuner was installed for that very reason. I guess every bike is different, but be careful and keep an eye on it.

Thanks, very good to know. Pipes turning slight yellowish tint usually means a lean conditions, right?

Not sure, as I've read conflicting info regarding the color and what it means. Everything else indicated it was far too lean though, and the heat from the engine seemed to be much hotter and it warmed up more quickly than it did before.
