Couple Problems

[Banage]

#1 new plug, rode it 10min. home, no spark this mornin. Black as can be. Same # plug I ever use, Normal gas, no high octane, or additives.

#2 My oil is dark gray. I am thinking water, been under a few times, but not sure. 4 stroke honda 200. Any ideas on these???

Grey oil means water. The best way I know to dry the inside of a motor is to use tranny fluid, which absorbs water. Drain the gray oil, and then put it 1/2 oil and 1/2 tranny fluid. Warm up the trike good, but do not put it under heavy load. Drain out the mix, which will take all the water with it, and then put in fresh oil.

Not sure about your plug, you may have just cold fouled it. Try another new one and if that fixes the problem, throw the old one away.

You could have a weak spark problem. Have you checked the exciter coil yet? If so what was the ohm reading you got? You need to have 215-240 ohms for it to have the proper spark. ;)
