Ok i'm going to start off by giving the history of my bike. Its a 2011 fz6r raven. Purchased in may of 2011. It has 9,000 miles, and a full two bros exhaust with juicebox. Its had its 600 mile service done at the dealership, and it had its 4,000 mile service at the dealership. The bike has never given me any problems....until now. This just started happening and has occurred on 2 occasions. When cruising the bike at a constant speed, let's say 85mph, all the lights would dim and my speed/rpm would drop down 3-5mph, like its "dying", but would quickly return back to normal. Then again seconds later, it would "die"(lose power) but then would return back to normal. It kept constantly doing this for a couple min, I always use my high bream while riding on highway, so I turned it off thinking maybe its draining power/electricity, and ever since then have not used my high beam. But today it did the same thing on the streets, so i'm having trouble figuring out what might be causing this. Can it be my battery is no good anymore. Or maybe my juicebox is using too much power? I'm going to take it to the dealer tomorrow to ask questions, but wanted your guys opinion first, any input would be greatly appreciated, thanks in advance.
