FSE450 overheating question
One concern I have with any 450 is the tendency to run hot. One good way to encourage a carbureted bike to overheat is to jet it too lean. I wonder if an EFI bike is less prone to this as they always get the proper fuel/air mixture?
I am curious to what some of the FSE450 owners have to say about this? Greg |

Have you disconnected the efi map selector cable under the tank?
Stock the FSE is on a very lean map, making it run hot. |

On my '05 FSE, it was the yellow and blue wire. Very simple and my bike really woke up and no more overheating. Bob

Is it one wire that is yellow and blue?
Is it one wire that is yellow and blue? Or is it a yellow and a blue wire (2 wires).
If so, is it the wires that go into that white plug? |

Not sure about any white plug, but there are two cables screwed into the EFI casing under the tank rear end. Disconnect the one cable which is yellow AND blue. There is a connector you can separate.

That is correct. I then wrapped the ends with elect. tape. U need to do this for it to run cool and much better all around performance. U can also look them up on the wiring schematics and find where the yellow and blue wire is.

04 Fse 450
Ok guys heres a question. I have noticed alot of people talking about how they are disconnecting and connecting these wires.
What is this all about? My 04 FSE 450 (1300 miles with FMF pipe) has started to pop during decel and after giving it a good rev, it will pop right when I let off in the height of the rev. This makes me assume that it is running lean (and maybe hot, but i can tell) Like I said I want to make sure that I dont run it lean and screw something up, overheat it, etc. I want to know about this wiring stuff. If somebody knows, please fill me in. I want to know if this will solve my bikes popping (assuming that it is running lean) Hope to hear from somebody soon. Thanks! |

The '04 fse does not have the yellow/blue wire disconnect remedy. '05 only. Someone else with an '04 fse should be able to help U on running lean? Good luck.
