    flywheel weight

    Curious what the popular opinion is regarding a heavier flywheel or mx. I have an 06 450 and only ride mx. I know everybody loves them for woods riding but would really like to hear what people who ride mx have to say about a heavier flywheel. thanks

    250x engine serial number

    is there any way to determine the year model based on the engine serial number? i purchased a 250x motor for a kart and was told it was an 05 model. the engine number is 5300789 thanks
  4. Okay, thanks for your help. Wow, I sure don't get the warm fuzzies from your responses or is this just how you reply to newbies to break them in. I can read, I just thought I would get an "expert" opinion.
  5. Well, the instructions call for the blue needle, 5th clip, however the note recommends the red needle maybe desirable for hot and humid conditions. Thanks for your help.
