What's up everyone. As some of you may not know I have a Ninja EX500. I have been having this reoccuring problem with my plugs... I have to keep changing them. No really... each time I put in a new pair the bike is fine for a while then as usual it starts dropping one cylinder in the middle of riding. It drops it for a few seconds then kicks back on. As you can guess the bike is jumping speeds as it kicks on and off. My other half says it is a carb problem (such as too rich a fuel mix) due to the fact that I have a Jardine exhaust (without the baffles). The bike didn't have this problem before I dropped it last year. So does anyone know how to adjust the carbs and what they should be set at? Freakinout - you should know this since you have the same exhaust as I. Help me out.
