Riding home from work tonight in the rain, the bike died. Pulled to the side of I-279. Cold and wet I was pi$$ed. Hit the starter, it fired but sounded strange both sides not firing equally. Back on I 279 not even a half mile and it died again, rolled back to the side of the road. Turned the petcock to res. tank just for the heck of it fired back up and rode another half mile running rough died, back fired, died. Pulled the choke fired up and back on the road only six miles to the house. died once again and fired again. Maybe the rain got something wet, never had a problem before in the rain. The only change I made was new NGK I-plugs. Pulled the plugs when I got home right side black and sooty left side nice color. I changed back to the reg. ngk plugs and will try to ride tomorrow.
