    Default Advice On Exhaust & Installation

    As some of you may know I recently purchased a 2009 Harley Davidson Fat Bob. I want to upgrade the exhaust on my bike to the Vance & Hines Big Radius 2 in 1. I like the look and I like the sound of these pipes. The link is a before and after. The only difference is that I want the black pipes instead of the chrome.

    What I would like to know is if anybody has other recommendations for pipes and where to get them installed. I appreciate any help I can get with this especially since I am new to all of this. Thanks for you time.

    Peace

    Call Kelly at Dynges Dyno, he's the best local guy in Visalia, does a lot of work on Harleys, too... since you are talking about changing your exhaust flow, your air/fuel mixture may need to be adjusted, which means you'll need to change your carburation (if Harley's still using carbs?) or change the computerized 'tune' for the fuel injectors, either by re-programming the current 'tune' or installing a power commander (a computerized over-ride box you can buy for more performance).

    Anyway, call Kelly, 977-2258, he'll be happy to talk to you about it, tell him you're a friend of mine & on the board... he's on here, too!

    Oh, and one more thing, I'd wait for a little bit, get used to your bike as it is before getting too excited about after market stuff... you'd hate to scuff up new parts if you have a little drop, and its probably easier to get used to riding it for a newbie in stock condition, usually new pipes give you a little more hp! So give yourself a month or so before going too crazy on after market stuff! Just my

    I'll look into these as well. I appreciate the heads up.

    You know I'm not doing all that DJ. I will however get in touch with Kelly. I'm not getting the pipes until I am absolutely sure what direction I am going so it may be a few months and I am not in any hurry. You are right though, about dropping my bike. I don't want to see that happen at all. I'd probably throw myself under the bike to keep it from getting scratched. Thanks for the advice though, I'm sure I'll be hitting you up again for advice.

    for a harley id say save your money (and ears), keep the stock exhaust, and upgrade the suspension. the bike will feel waaayyyyyyyyyyyyyyyyyyyyyyy better if you drop a grand in suspension over some motor stuff that might get you 5hp.

    thats speaking from experience as well. my dad has a dyna lowrider and he got suspension and steel braided brake lines first and the bike is a ton better at stoping and cornering which is a heck of a lot better then making more noise.
    Enjoy the moments, they wont last forever

    For safety I'd like to be heard coming since bikes are hard to see. I intend to the the suspension as well so we'll see what I do first. I appreciate the advice though.

    Give me a call or come by, since you're local.
    I can save you a ton over the Hundred Dollar dealership.
    With the right exhaust & tuning, You can make that bike run a whole bunch smoother, without busting eardrums. I have a lot of HD dyno graphs you can look at.

    PS I have all of the info that you need for your suspension setup & can do the work too...Ask L2Fly how her's came out

    dont get in a blind spot. best way to be seen. when i rode on the street i trained myself to try and always be infront or behind the car next to me. just cuz they hear something does not mean they are thinking if its next to them or not. loud pipes are good in theory but i know a lot of people that have been hit and had loud pipes on.
    avoiding accidents is all up to you and how you ride and how well you pay attention to whats around you.



    Biggest peice of advise i can ever give anybody is ride like your invisible. act like no car sees you or hears you or knows your there. if you ride with that mentality you will be able to ride an electric bike without problems.

    They call it a HD "Race Tuner" & not even the Dealers can figure out how to tune them correctly. Don't waste your money on that.

    That is becaus the oxygen censer over rides the tuner go to a web site named Night rider .com electronics and it will fix that problem with out tuner of any kind they make 3 of them the best is the one that goes to 13.8% read the site and you will see what I mean I have been runing it for 3 years and it works great no more over heating.

    The oxygen sensor only overrides the ecm at steady highway speeds (cruising). It does nothing for around town or on/off throttle riding, which is where a majority of the drivability issues are found on the newer HD models.
    Dynojet sells a O2 eliminator plug ($12), which does the same thing.

    No it does not do the same thing. Just like you say a race tuner does not work that H D can't work on them. Mine has ben installed for 2 1/2 years and my motor has had extensive work done on it and I can tune it with out any problems so why can't they, they dont want to read and a child could do it

    Also remember that the only time that the oxygen sencer works is when the ECM is in closed loop that only happens at a steady speed or idle so if the Night Rider don't work why does the oxygen elimator work

    An oxygen sensor eliminator fools the ECM into thinking it is running at it's set point, so it prevents the bike from leaning itself out.
    Nightrider changes the resistance to fool the ECM to operate at a different value. End result, Nightrider only works at steady state throttle highway speeds & not at idle. It does nothing to address acceleration or on/off throttle issues
    Neither is a substitute for a custom tuning.
    Sorry if you misunderstood me.
    I have a dyno & would be willing to show you the difference.
    Most people think louder is faster too.

    I don't misunderstand what I said is nightrider works in closed loop same thing is affected as the elemnator you sugest the people that built my motor is runing a sporster at Bonivelle this year and on a dyno a carberated 883 sporster is puting 154HP to the rear tire owning a dyno does not mean s***

    Exactly! In time I'll get it but for now I'm just trying to absorb it all. Went to the HD dealership today and talked to them about the exhaust again and I really don't feel comfortable paying that much for exhaust work. Even on my mustang the flowmaster weren't that much.

    First night of the motorcycle safety course was tonight so now I have 2 more to go. Really interesting information provided to us tonight.
