Hello everybody. I'm a proud new owner of an 07 Ulysses. I have to say, I am amazed at what an incredible resource this forum is. I have never seen an online community so helpful with the Japanese SS I was riding in the past. With that, I have a couple questions for you all. (I did a search, but couldn't seem to find the right combination of search words to find the answer I was looking for) A friend and I were trying to reset the TPS as per the maintenance schedule and for the life of me, I could not get the throttle to zero out. It would go all the way down to 0.2 and there it would stay. We went ahead and reset the TPS anyways. The bike does seem to run smoother, but I am still worried. 1. Am I going to have problems down the road because the throttle was not at zero? 2. Why wont the throttle zero out? Thanks all. |

When you zero the TPS, you are telling the computer that what it sees coming from the TPS is to be seen as being zero. The TPS is a potentiometer and it isn't all the way down at a closed throttle. If it's running right, the TPS was done right. |

Osup, Mine would only go down to .2 unless I HELPED it down to 0.0 by backtwisting the throttle. Hold that zero with your throttle backtwisted and at the same time reset the TPS on the computer screen. Simple as that. Now you won't be .2 off. Hope that makes sense. |

Mine did the same until I opened and snapped the throttle back. |

Thanks for the replies guys. Yeah, I did backtwist the throttle and it would not go to 0.0. I snapped the throttle a couple dozen times too and that did not help. I guess I should not worry about it as the bike is running great. I'm just a worry wart about these kind of things. Thanks again! |

I'm just winging it here but since there apparently is a need to reset the TPS zero point periodically, it's no wonder that the zero some times drifts. The only thing I would worry about is this: you should always make sure that when the cable idle adjuster is used to bring the TPS pot down to zero AND you've snapped the throttle a few times, that you turn the idle adjuster cable (loosen) counterclockwise a turn or so more. This ensures that the end of that cable idle adjuster is not physically touching the throttle lever assemble (see pages 4-118 and 4-119 inthe service manual) anymore and that enables you to actually backtwist the throttle a hair. Another possible reason for not being able to adjust the TPS potentiometer down to 0.0 is throttle cable adjustment being off. See page 1-42 in the method to do this. You'll see in Figure 1-46 on page 1-42 that one of the throttle cables is called the Idle Control Cable. It may have been just a matter of adjusting (loosening)that particular cable a fraction to have got your ECMSpy screen to register your TPS reading down to 0.0 The whole idea is to get the butterfly valve in the trottle body throat to close completely because that is the TPS zero point. The shaft that turns that butterfly is also the TPS pot shaft. Feel free to chime in if this is not correct. (Message edited by electraglider_1997 on September 23, 2007) |
