    free LT80 mods, new to this

    i bought a 1980 something LT80, doesnt run right now but i found the starter relay is bad so im getting a new one for it. i was wondering what i can do to this for free to get it faster. i looked around for the clutch mod but still confused on how to do it and i read the offroad.com article thing. also the air filter, do i just need a filter on the carb or does that lower thing need to have a filter to, the lower tube out of the case is just a crank breather right? Thanks in advance

    I read the offroad.com thing a while back. I consider it flawed.
    Removing 2 of the front clutch rollers will increase the stall speed slightly.
    Shaving the head .030m will bump up the compression.
    Gearing up will increase speed.

    The only filter I know of is the air filter.

    If he has all the stock air box on, he won't need that.

    "do i just need a filter on the carb or does that lower thing need to have a filter to, the lower tube out of the case is just a crank breather right?"

    He should only need the carb air filter.

    The other is where the air is sucked thru the clutchs.
