            try new plugs first!
            be very easy with the started fluid... a little goes a very long way... if you had ever seen a catastophic conrod failure (due to starting fluid) you would understand... but, you could just take my word for it?

              alright took them out again and they where soaked. so i put one of them 2 inch wire wheel brushes on the drill press and cleaned all the carbon off them and ill let them them sit out over night to dry up deep on the inside. also let the cylinders dry out over night. the plugs are only a week old and not cheap. i shouldnt have to buy new ones.

                (A) Do not use a wire-wheel on your plugs again. It strips the coating off the ceramic, ruining the plug. Spray them down with carb cleaner and hit them with a toothbrush (nylon bristles) if you want to try to salvage them.

                (B) Plugs foul. It doesn't matter how expensive or cheap they are, plugs foul, especially when you have a fueling problem (which is what it sounds like -- a bad float or dirty/clogged jets). Replace them and address the issue that caused them to foul. When you said they were wet -- were they wet with gas or oil?

                (C) If the answer to (B) was fuel, check your gas tank and carb bowls for the presence of an orange paste. Fouling overnight can often be associated with rust build-up in the gas tank (the rust settles when the bike is parked, clogging passages at that point; when the bike is running, the constant in-flow of new fuel tends to keeps it stirred up, especially if they were just cleaned). If there is no orange paste or signs of rust in the tank, drain a cup of fuel out of the tank (via the petcock) into a glass container and check it visually -- any signs of water, contamination?

                (D) If you paid the shop to address your carb problems, call them or place a stop on the payment. It taint fixed.

                And finally, the fuel-air mix will not detonate if it has more than about 18 to 20% fuel vapors by volume (too rich) or less than about 11% (too lean). Both conditions can soak plugs.

                    Sounds like you are getting a bit to much gas in there. Take it back if they were the ones to work on it last.
