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.
