2005 VX1100 won’t get up to speed
I am having an acceleration issue and a top end speed issue. At around 8500 rpms it tops out at 45 mph. Normal top speed is 59. I accidentally left the tank just under half full with no stabilizer over the summer. I added 10 gallons last month which I thought would counter possible bad fuel. Could this be a cause of the lack of top end?
It’s running a little rough at idle as well.
Thoughts anyone? Thanks.
