Hello I am new to the fourms but I joined because I have heard there is some helpful people with mechanical knowledge on here that have maybe run into the same problem in the past.



So here is my problem when I got my new bike a 2005 YZ250F I took apart the carbaurator to check all the jet sizes to see if they were one hundred percent stock and they were but the problem is I did not have a manual when I took it apart (I do now) and then I accidentally took the throttle positon sensor screw out and then pulled out the throttle positon sensor coupler/throttle position sensor and now have no idea how to put it back on because I just recently took a flat head screw driver and then turned the inside of the throttle positon sensor to try and wind up the spring because that is what I read on this website for a different motorcycle as there is hardly any info on the 2005 YZ250F https://thebikersgarage.wordpress.c...g-a-throttle-position-sensor-on-a-motorcycle/ this then further confused me more because I have turned It many different ways and every time it runs a little bit different and the voltage when checked with a multi meter is not in spec but then sometimes is depending on where I turned the notch and put it on. I have searched all over the internet but not many people have this problem because this piece is not supposed to come off. I have not been able to get one good ride since I bought this bike because of this problem and have been struggling for weeks to get some help on this situation that is why I decided to come on here and get some help. Thank you very much.

Go to Service Honda's site and look up the parts fiche for that bike.

It should show how things go together. It won't give you specific installation instructions but it may help just to see things.

It looks tome that one part goes over the flat piece on the carb and the screw holds the plastic piece in place. I had a 2005 YZ250F but didn't mess with that part of the carb so I can't remember much on how that piece goes on.

Thanks
