I need to know what’s causing this. For the past week I’ve noticed that my 98ti when idled it would kind of jerk little, nothing major but noticeable to me since I know how she rides. I decided to check the plugs and when I took out the first plug, the one closest to the oil fill cap it was wet with oil. The plug looked ok other than being soaked with oil. I checked the others and no problem with them, dry and healthy look on them. I went out and got me some new NGK’s and changed them all. I will check this evening to se if the new plug is wet in oil. What may be the cause of this? Any advice would be appreciated.
