    Simple auto-x question.

    So I pretty much left the 200x wiring harness (electrical) on the x when I installed the 81' 200 motor. Right now I have a 200x carb and spark plug (dr8es-L), should I run the 81' 200 plug? (What is the 81' plug if I need to). I have the open uni filter plugged in, should I put the air box back on? Runs o.k., but could be smoother, some times it idles some times it dies, heck, it is over 25 years old.
    83' 200x (son's). 85' 200 auto-x & 85' 125m (daughters). 84' Tecate(?). 85' KXT Tecate (mine!, mine!, mine!.)+ some others but don't feel like typing them in.

    I'd probably clean and rebuild the carb, sounds like an airway may be plugged or plugging. Anyway, rebuilding the carb would be the first step and proper adjustment from there. I always run an air box, lid off with a Uni or K&N filter element.

    When I built mine. I used the 200x Carb, and the 200 plug (I believe that the 200x plug is the same) And the factory 200x air box.

    O.k., thanx fellas. I did what I was told. The only thing swapped was the motor. 200x carb, boot, plug, wiring, and all mounting hardware. I also did what RapidRick said and put back on the stock airbox (holes all ready drilled in cover). I'm at 4700ft so I moved the clip second from the top (top made it bog) and turned the air/fuel screw another 1/8 turn. It quieted it down and runs much smoother, does not die at idle as quick and will actually idle when it wants to. I used up all my new and decent plugs so I bet it will idle after I go to town and get more plugs.

    how much more power do you get running an open box?
    no more toys maybe buy a 250r?

    past:
    86 250r
    88 quadracer
    83 200x
