Sometimes the wiring will get wet (especiall after a wash) and run rough for awhile. Has it fixed itself yet. If not try changing the plugs.

RE: chugging and back firing
Good advice from above, one other thing is you might have a little water and or trash in the carb, sometimes when you don't have a full tank of fuel and you let the bike sit out in hot sunshine during the day and then it cools down like it did in Myrtle you can get condensation in the tank. If you have a little water in the float bowl the vaccum as you accelerate will suck it out and the engine will run rough but clear out, but if you have a lot of water in the float bowl it's clean out time. Also like previous mentioned you might have a plug that was trying to foul. Like Terry and the others said if it's still not running properly change plugs, do a intake vacuum leak test and go from there. You can do a scearch on intake leaks as this has been discussed several times before.
