The gas is fresh, I ran out a couple tanks of different gas to make sure. The variation in rpm is 500. The needle will bounce back and forth. Cruising down the highway it feels like the bike starts slowing down but if you goose the throttle it takes off. Repeats every time.

Ok I checked the battery voltage at 5k and its only 13.9. Isn't that low? Battery voltage off is 12.9 so that's ok.The chain is a bit slack so that was a good suggestion. Fixing that tomorrow. I'll check hoses too since I had the tank off to put in the k&n filter. Maybe a hose popped off.

I have a 97 bird with a Delcovic slip on exhaust and a k&n filter. I beginning to notice a surge only at steady throttle at highway speeds. The bike has almost 20k and has the cct replaced and has been cared for. I have also noticed the tach fluctuating when this happens. Anyone ever heard of this or any suggestions?
