hey guys i just got a 1992 yamaha warrior from a buddy of mine. it has a white bros pipe k&n air filter and thats it. i was rippin around on it ran great. washed itand got all the wires in the back because they were covered with mud i started it up and put it away for the night next morning it wouldnt start. i have no spark whatsoever.the wire that hooks to the negative on the battery is a little frayed but all lights turn on. my dad said it could be a bad ground. what does this mean. he said that since the wire is frayed it could be it. the bike turns over but will not sputter. im new to 4 strokes so any help would be appreciated thanks guys and great forum
