So I got the bike out today after being in storage for about 7 months. It fired right up (had fuel storage additive) I drained the fuel and put fresh 93 octane in. I rode it for about 50 miles over a span of a few hours and it ran great except for about the last 5 miles. I was accelerating quickly and it all of a sudden dropped down to around 8k rpm's and eventually 6k at WOT. While this is happening at wide open throttle if I back off the throttle about 1/3 of the way it will continue accelerating but at a much slower rate. There are no codes, the exup system is cycling at start up fine, the fuel pump sounds fine and the air filter and spark plugs were changed just last week with less than 60 miles on each. Any ideas?
