Has anyone seen if their pipes glow orange during warm up. For the last 4 days when I started my bike up in the early morning to warm up I'd walk away to put my gear on and come back with the pipes glowing! To me this is a very lean condition and cant be good for a new motor.... Anybody else see this? |

Yes, they do it, especially the rear. I know the headers are thin wall tubing, but I don't know how thin. I'll have the pipe off this weekend, I'll see if I can remember to measure it. |

Does anyone know if this is correct? Again the only thing that sould cause this is either a lean condition or a timing issue. I find it hard to believe that the manufacturer want to warm up an engine under a lean condition. |

Try to reset the TPS.. and do that every time you start the bike,. The heat is generated, because it is not getting enough fuell.. fix it.. |

I can see why the pipes might get like that on a dyno, but just sitting still warming up to operating temperature ... No! Mike |

I thought in the case of warmup the fuel was burning in the pipes yeah the rear ones get orange and the front of the silencer can get quite hot as well. I have seen mine medium dull red. I would not worry about it. unless it becomes excessive. |

Use the search funtion on this great website they made it for that reason. Turn on the ignition, DONT START THE BIKE. fully open the throttle and let it go hold it for at least 2 seconds. So.. 1 x open en count 21, 22 2 x open en count 21, 22 3 x open en count 21, 22 It is a build in function in your throttle Every time you open it full it sens a signal to the ECM. when it gets 3 x the same signal it sets the TPS sensor to zero.. Do that 3 times after each other and start the bike, have fun (Message edited by Easyrider on November 05, 2009) |

You can also check TPS function in Diags. To get to diagnostics mode, make sure your security theft system is set to "Off". Then hold down the Mode and Toggle button while turning the key to either On or Park. Once there, you can step through a bunch of stuff, two of which are "TPS Percentage" and "TPS Voltage". TPS Percentage should move smoothly from 2% to 100% as you twist the throttle from closed to fully open. Mike |

oldog, When I have a 1125 on the dyno for adjusting the fuel and spark map, IT IS ALWAYS LEAN WHEN IT IS DOING THAT... So I DONT agree, in this case.. It is a lean mixture ad not good for the bike.. |

Easyrider, your inputs always spot on and welcomed by me. Question though: every time I check my diagnostics my TPS show 2%-100%. Why the need to do TPS reset every time we start our bikes? Is there something that changes it during a normal or spirited ride? Thanks for all of your contributions here on BadWeb. Bob |

The "ignition timing" will help the most with getting rid of a low timed engine...AND the red exhaust...! Excessively hot exhaust at low speed/idle is a major symptom of low timing. More fuel, secondary help. Been there. While I don't spend hours and hours on a dyno, I do have many years tuning, everything from a 1200cc twin on carburetors to a 400cu.in. hemi with a supercharger and many engine configurations in between. Low timing WILL kill the low rpm area. Along with the rest of the rpm band. The little "Pass Button" on the F1 and Indy cars..."losta timing, a little fuel". Mike |

Easy Rider, you check the engine cold ? I am refering to warm up operation. while the bike is warming up and sitting at night I have see the pipes turn orange (rear) in the frame area my bike '08R has the latest flash as of delivery. and runs quite well its in the shop for a coolant leak. |

"To me this is a very lean condition and cant be good for a new motor.... " The exact opposite is true. Fuel is still burning during initial opening of exhaust valve during power stroke. The flames enter the pipes and heat them up. Fire at 1,200oF makes thin stainless steel pipes glow. Go figure. It's a fire breathing performance engine, just 1.1L producing 146 HP. |

Bob_thompson, when in read the TPS signal before a run, and then shut down the ignition and read it again before i start the bike there is a difference. When I compare the 2 runs, in the same condition mesuared, there is an AF difference of 0.5 af, from my opinion that is too much. That's why i suggest every body with a original fuel map too do this every time before you start the bike.. |

Easyrider: Sorry if I'm slow here. Do you open the throttle fully and hold it open for two seconds, or open it fully for a moment, then leave it closed for two seconds? Is there any feedback or indication you've done it right? |

Yes, you open the throttle fully and hold it open for two seconds, 1 second i spossible but 2 is save. No just let it go open your hand and do that 3 times. No it's right when you do it this way.. |

Sorry EZ >>when i add fuell it is gone and running 13.6 please explain that << I was saying that I have it wrong, so I learned some thing Quenching or cooling from the additional fuel, I dont worry to much about it the glowing pipes,the pipes getting hot is less important to me than letting the engine warm up (prevent fowling of the sparkplugs) |
