IF U CHANGE THE EXHAUST DO U HAVE TO HAVE THE COMPUTER REDONE OR JUST CHANGE THE PIPES? WHAT KIND OF PIPES WILL GIVE A TRUE V-TWIN SOUND?

The 1800 will NEVER sound like a HD single-pin sound. You want that sound you want a 1300 that has a single-pin crank. 8)

No, most members run without a fuel manager while having aftermarket air intakes and exhaust and have no problems at all. The following is from the “Sticky” thread called,“Air,Fuel,Motor,Missives…” and the first post by Tapper. The entire post is filled with great information on the VTX engine.

After Market Fuel Computers

This is a good time to talk about aftermarket fuel controllers, so lets hit on what they do real quick. The 1300 guys can manipulate their A/F ratios by changing jets, but it’s a bit more complex (and expensive) for the 1800 riders. For the VTX, there are basically three types of controller available. All three do exactly the same thing – they manipulate the amount of time the injectors are turned on during the intake stroke, by intercepting the voltage the ECU sends to the injectors. How the decide how much longer or shorter to turn the injector on, varies a bit though, and that variety is important thing to know when selecting which controller to use on your bike (if in fact you choose to use on at all – none of them are ever really necessary, regardless of what pipes or airboxes you add on to the bike.)


It’s also important to understand this: None of these controllers is ever a necessity, regardless of whether you change pipes or airboxes on your bike. The stock ECU will, in almost every case, adjust to the changes in airflow you’ve caused, and give you a reasonably good A/F ratio.
But you should understand, that the ECU is not programmed to give you an A/F ratio that is optimized for horsepower from the factory – instead, Honda worries about things like pollution, engine temperature, and rider perception, and so the ECU can be said to be “de-tuned” in order to address these other concerns. So the real function of these add-on controllers is to correct the error (or eliminate the de-tuning) that Honda induced in your fuel curve on purpose, in order to reclaim the lost horsepower and improve engine efficiency (possibly at the cost of making more pollution, hearing more deceleration backfiring, etc). Adding on aftermarket pipes or airboxes can sometimes exaggerate this de-tuning as well, so we need to be able to modify our fuel curves to match the configuration of our bikes. Got that? These boxes aren’t necessary, but if you’re hunting more horses, they can sure find them.

Welcome to the board!
Bookmark this website, http://tech.vtxoa.com This is the sister site to this message board and contains all your How-to/Tips/Tricks/Why’s and links to other helpful sites for your new VTX.
There is also a helpful red Search icon at the top of every page(not the Google search). Enter your item to be searched in the "Search Query" section and click the "Search for all terms" bullet under the query. Then go to the "Search Options" section and choose a board from the "Forum" drop down menu. This will limit the results to your search so you won't get pages of "Fluff" .

The pupose of the "Search" is to offer a member the opportunity to research his/her question better. There is so much information from past threads that you may never see because that member is no longer here, or doesn't see your new post, or just won't respond to the same question. So use it to your advantage and enjoy the board! View this funny and informative film about posting and searching…

Also, take a few minutes to familiarize yourself with the forum. At the top of every board there are threads that are tagged as "Sticky" These threads are "Sticky" because they contain very important/valuable information about the VTX and everyone should read them.
The thread at the top of the 1800 tech board called, "Air, Fuel, Motors..." will answer most of the performance questions...

Also, update your Profile to include what type X you have to your Signature line. I.E. 1300/1800/C/F/N/R/S.

The best sounding pipes, well, that's a personal question, best answered by you. What I may like, you may not. Best thing to do is meet up with a group of VTX riders and hear them in person. Look for a gathering of Ohio guys on the Ohio board to see when&Where they are meeting for a ride. 8)
