Fellas,
I have been searching through the recent posts and was looking to see if the Cobras have O2 bungs for the factory sensors. If its in here somewhere I appoligize for the lack of searching and please direct me in the right direction. I would feel certain that they would have O2 bungs however just want some clarification. Also, I noticed when most of the exhaust talk started it was back near the birth of the Stryker. How many of you guys have been running the Cobras without the Power Programmer? Any problems, issues, running too lean? Once I go intake I will go the programmer route. Any help would be great. Drilled baffles just ain't cutting it... ;D

I don't mind the drilled baffles... but then again, most of my riding is done at 2AM on (my work hours) So I'm all alone and everyone's asleep... My neighbors would freak if my bike was any louder at that hour.... I think it sounds a helluva lot better than before it was drilled... What's more important is the way it handles and I'm satisfied with the torque....and this is coming from a sportbike rider.... Blows away any other cruiser I've owned as far as passing speed. (Plus...at the moment I don't have the funds for any mods due to my hours being cut so I have to be happy with what I've got at the moment) lol

Yea I drilled out the baffles second day I had it. Pacified for a little while. Just not quite enough for my taste. Just wanted to see if anyone had any ill affects by not using a programmer. And my neighbor is an a$$ so it would be great to wake him up on occasion ;D

i waited till the day after my first service to drill mine, didnt want anyone at the dealership to *****

 

[spoole1]

Any of you fellas have anything to add here? Yamaha dealership is saying that the commander is needed, however I know they are trying to sell parts.

From what I've been told and read, it wont hurt to run pipes without a fuel programmer. More discussion here

Thanks for the link..... I am going to pull the trigger on the pipes today. IMO adding exhaust to a bike shouldn't be any different than a car or truck as long as all the O2 sensors are accounted for...... I have put exhaust on everything I have ever owned. Hate to break the trend...lol Guess I will pull the plugs about 500 miles or so after the pipes go on and see how they look. Anyone have a sound bite on those pipes by chance????

 

[backinblack]

I think you'll like them. Check out Youtube for sound clips.

 

[SillyFingaz]

Funny.. I was informed that being tht the bike was fuel injected and not carbureted(SP) there wouldn't be any need for a programmer. ???

 

[UrbanRage]

If the bike was carbureted it would need a jet kit installed. Since the bike is fuel injected it would be wise to install a fuel management controller.

 

[kcl-labrat]

you need the controller to run optimal

 

[ironman1964]

I spoke to the service manager at my local Yamaha dealer. Not saying he knows more or less than anyone else. He says that exhaust only the stock computer can and will adjust to the change with no problems.

any info is good info

I'm running them with no baffles and I have "dead spots" in the throttle while cruising. Spirited and WOT throttle is great, but its just at a mild cruise is when I can feel the dead spots. I guess i'm going to have to get a programmer.

So my theory is-
Do you have to have a programmer? - No
Do you need a programmer? - Yes

i might sound like an idiot but what do you mean exactly by dead spots ???

 

[Dohduh]

I have also noticed when I ride there are dead spots. I have the cobra sweeps with the baffles removed.

 

[kcl-labrat]

Like a lack of throttle response or a low volume spot in the exhaust tone

 

[01WS6]

Like a miss. As in your barely on the throttle and nothing is happening till you twist it a little more. lol

 

[kcl-labrat]

Ouch that would be weird

 

[UrbanRage]

I have the same problem. When you are in first or second and putting around with steady throttle, it will cut out. I beleive that is due to the bike running richer than normal. I think once I install the fuel programmer this will go away.
