    Default Speedometer freaking out

    Hey all I have a quick question for you guys. I went for a 4hr ride today and I realized while I was doing 75-80 mph the speedometer would freak out and go to 100 down to 60 then back to my actual speed.

    I did just get new tires installed please help me out .

    Thanks in advance

    This sounds like the speedo sensor needs to be cleaned. Take a look at the following thread:

    - My memory's not as sharp as it used to be. Also, my memory's not as sharp as it used to be.
    - God grant me the senility to forget the people I never liked, the good fortune to run into the ones I do, and the vision to tell the difference.

    I had that to happen to my 07 years ago. After doing about 2-3 start ups and recycles, it never did it again.

    You're welcome! I also had a bouncing speedometer which was resolved by cleaning the sensor.
    Note: a tablespoon or so of oil could possibly drip out when you remove the sensor, so you may want to put a cup or a rag underneath while cleaning it.

    Lastly, the advanced search feature works very well. There is a lot of information here if you search. Someone will usually answer your questions quickly, but searching is even quicker!
    You can also use Google to search the site by entering your search terms and adding site:m109riders.com

    Good luck, and cheers!

    It is just metal flakes on the sensor since it's a magnet. Cleaning it will solve your issues. How old is the bike? If it has a lot of miles then you should listen for some noise in the secondary area. There is a bearing in there that could wear which might be where the metal is coming from.

    My bike is a 2017 with not even 6k on it. This is the first time seeing this, I did just change the tires would that make it freak out ?

    So when I pull out the sensor and oil comes out should I replace the oil or clean it and put it back dry ?

    Clean it and re install the sensor. Any oil that you lose will be negligible.
