      @@ianreid8634 very possible it’s your tester giving a low but consistent reading!

      @@ThatsAyz125 it all really depends on your Tester. Most our YZs were 120 psi and We had a 125 bored over and it was 150 psi

    What ended up being the issue? My bike is making the same kind of rattling sound up in the high rpm’s and the compression is solid as well around 150 psi

    hey bro, can you tell me if the rear frame of the bike is aluminum? and also what year is it, because I wanted to put a restyling kit, but the rear part doesn't fit ... and if so, can you give me advice ???
    Thank you!!

    • @MintyMotos
      @MintyMotos  Год назад

      The restyle kit will only fit 2002+ models, if you have one older than 02 and really want to restyle it you can do some mods to make it fit, I have a video on here showing what you need to do.

    Confused as to why you said kick it ten times? You should be kicking until the gauge levels out and stops moving up

    • @MintyMotos
      @MintyMotos  Год назад +1

      It’s just a rule of thumb, it should take less than 10 kicks to get the reading so do 10 and you’re good!

      He wasn’t looking at the gauge while he was kicking it. Did you watch the video? He kicked it 10 times as a good measure. Certainly at that point the gauge is reading it’s highest. Would it have been less confusing to you if he just gave it one kick?

    This compression tester is a crap. Normal stock yz250 compression is around 220-225 psi.
