08cbr1000rr hesitation at around 3500rpm till 4000rpm
Hello everyone! Cheers for good weather to ride finally here in South Dakota (when im done riding) ! Have a issue that i hope someone can help with. When reving, the bike revs fine..it idles low once in a while like a spark plug is bad. When i go on interstate and hit roughly 3500rpm it hesitates like its not getting a spark but once it hits a certain point around 4k rpm it hits it comes back to life and goes all the way up fine till i shift. (I never rod the bike bad or do crazy stuff.) Last fall it did this and i researched and thought it was the spark plugs. So i tore it apart and got those changes. Longer process than i expected but fairly easy. So i got on n still no change. A couple weeks later my service light is on. It flashes 2 times. When i drove it, it is just on. I researched more and people say the vacuum hose wasnt put back on. So i am going to go back n make sure vacuum hose is attached but either way i still had the same problem with new spark plugs in. Does anyone have suggestions while i take top apart to check for vacuum hose being attached? Your help would be greatly appreciated!!
