    Spark plug issue

    Ok, I got brand enw plugs for my 200 about 4 days ago. I out one fo them in 2 days ago, and rode it all yesterday. Today it wouldn't start, and when i took the plug out, the tip is all black. What the hell could cause it to foul so quickly? It backfires some, and I'm pretty sure the timing is on.
    Also, does anyone know a quick, redneck way of fixing a leaking valve stem? I slathered it with super glue, and it half worked, but I need the other half full of air, lol.

    You may just have some dirt in the stem causing it not to close properly. Good luck getting that out now that you've glued it. There is a special tool for them or sometimes the aircap itself has the tool built right into the top of it.

    As for the black on your plug that sounds to me like your runniing rich. you might have to lean it out a bit.

    Nope, the guy before me had put a tube in it, and found it it wasn't gonna work because the tube wasn't going ot line up properly, so he left it. well i aired it up, despite knowing it, and after a day, valve has a leak some wear around the base. So i've been trying to plug it using super glue.

    Oh, those stems can be found at your local atv shop or automotive store cheap. Might just replace it. OR tire slime might help in this situation... but it's messy.

    You can't fix a cut valve stem.
    If you cant seal the rim there is a tube with the valve stem
    in the proper place . I work at a goodyear store and we
    have to order these sometimes .
    The rim isn't always the problem as old tires leak thru the
    casing.
