Awesome. You guys uploaded this at the perfect time. My throttle is hanging and the slide vacuum plate seal was just replaced and I have a complete gasket set to put in it. Do you have to remove the TPS when cleaning in an ultrasonic cleaner? Also I just got an ultrasonic cleaner for this job, what solution do you use for cleaning carbs in there?

Does a 2009 yz450 have the means of a pre installed “tune” for when it’s unplugged like what you’re talking about?

Hi, what is the tiny hole on TPS? it has access to intake through a pathway

Who else thinks the slide in the FCR is hilarious looking, with its 4 little wheels?

My constant resistance is 4.64 K-ohms. Therefore, my range should be 0.6032 --> 0.696. My TPS is moved as far over in the "window" as possible. At this position, my lowest number is 0.894 k-ohms.

Do I need to take the TPS off and reset it, or has this one gone bad?

I messed up and bought a new TPMS because it tested with an "averaging" multimeter.

What happens when I have no measurement between the black and blue
