I am getting an intermitent hesitation , been trying to find a common theme on when it occurs but only seems to happen when at 20-22K rpm, not dependent on gear I am in. Notice it to be when either getting into the throttle (not hard) from the 20-22k or letting off the throttle at this same rpm. Tried new plugs and no effect

Any ideas what it could be?

thanks

 

I would recommend lowering your RPMs from Formula 1 revs to something a little lower.

Actually, I'm not sure the Space Shuttle has that many RPMs!!

(Sorry, I just couldn't resist)

 

mine has what i would call more of a stumble when i take off. at higher rpms it is fine. i an not sure what it is but i am leaning more on timing.

 

I would be interested in what people say as well. My bike "skipped" once last week and again last night. It seems to run fine and than cut-out for a second and pick right back up (much like you describe). I was thinking it could have picked up some water with bad gas, but I am not sure.

It is not throwing any codes.

 

Check the battery and electrical connections. These are the most common culprits.

 

Sorry, mixing work with my HD as I work with high speed turbo blowers spinning at 20K to 40K

 

I just put some Chevron Techron additive in my present tank of gas to see if this might help. I will ride up to Reno's Steet Vibrations tomorrow to see if this solved it.

Please let me know if you come across a cause as your description is exactly what I am experiencing.

 

mine did that before I added a tuner. went with SERT - 08 UC
