this is the ONLY thing i don't like about my Buell.
$1000 to put a pipe on it, and i can't even do the work myself.
i bought a Kerker for my old suzi for $250, and jets were $2 from the local speed shop. i did the whole deal in one afternoon. even if you double the cost of parts, (it was 20 years ago) it still costs about 1/2 as much as the F.I. Buell
plug chops are much easier to do than this spreadsheet baloney, and cheaper, to boot. |

what do you mean 1000 bux to put a pipe on?
Just buy a pipe and put it on. The ECM will take care of itself. I bet your old carbs couldn't do that?
Only dyno it if you want to squeeze every inch of HP out. |

HR_Puffinstuff,
I have a supplemental fuel controller in the for sale forums that might work for you. Would need to check with the manufacturer to make sure it works on the newer machines first. Instructions make it read like the install and setup are pretty easy. Bought a bike with this on it, putting everything back to stock and don't need it so I can't really say much more about it. |

Your ECM will not "take care of it" unless you're using the Buell race ECM and the Buell race pipe. The stock ECMs are calibrated for use with the stock air filter/muffler only.
We had a customer who brought his 1125R in to have it checked on the dyno. It pulled 128.5 RWHP with the stock pipe and air filter and was running just slightly lean. He came back a week later with the new Jardine slip on and K&N filter. The bike made 107 RWHP and was running WAY lean. So much for the ECM "taking care of it".
If you're going to mess with the air filter/exhaust system spend the money to get the software and get it tuned correctly on a dyno. You might be OK with average riding without doing any tuning, but if you run the bike hard continually or take it to track day, you're taking a much greater risk with killing your motor.
Just my opinion. |

My opinion is based on having a Dynajet 250i dyno and a 2005 XB12 track bike that I run in the local AMA and CCS Thunderbike classes. That and the 200 or so bikes that I've tuned. |

What if a person changes the muffler only and keeps the stock air filter? I see posts that say there is no ECMspy for 08 and up, and there is no race ECM you can buy. Does that mean someone with a 08 or newer bike has to leave everything stock? If Buells intentions have been to prevent riders from modifying their bikes, then they obviously don't listen to their customers like they claim to. |

Might have to do with emissions laws, you are not supposed to be allowed to tamper with the fuel system. Also ECMspy no longer supports it because development stopped for whatever reason, if the development had not stopped they probably would have update the software.
When I was looking at the 1125r in the dealer last week, it looked like it had a catalyst on it, of course there were two used bikes sitting there with Jardine on them right next to it. |

Greg e is right- the EPA and other government agencies do not want you to change anything that controls noise or emissions on any vehicle including motorcycles.
You'll notice that most times the parts say "for off road use only". Technically it's been against Federal law since the mid '70s. It's just that enforcement has been lax.A number of cities around the country have put noise laws into effect based on whether or not the exhaust system has an OEM stamp on it. I think the current fine in Denver is $500. We're expecting the state environmental department to start writing tickets based on noise emissions when they start sniffing tailpipes on bikes here.
It is definitely safer to just change the pipe and not the air filter, but bear in mind that the bikes are already lean as delivered from the factory to meet current EPA standards based on the "Urban Loop Test Cycle".The stock ECM has its limitations when it comes to accommodating aftermarket equipment.
There is a "combined spreadsheet" that can be purchased that is supposed to let you use ECM spy on '08 and later models but I haven't used it yet. I have a customer that is buying the spreadsheet so we can tune his '08 XT. I'll post something here after we have some experience. I think he found it on a Sportbike website in Ohio. |

ECMspy development stopped because of the spreadsheets.
Dragonslayer, you can get a fully programmable race ecm from your race parts dealer assuming you have a race license. Other than that, it is illegal to tamper with the ECM on a polution controlled street bike. |

I just recently bought a '08 XT and got a Drummer for it. I'm just hoping that changing the muffler only won't screw things up. |

It won't. It will lean the bike out a bit, you will get some popping on decel, but it will be fine. A tune is recommended. |
