Well I thought I had fixed this issue by downloading IndyTiger's custom tune, but it is still there. Basically, if I am cruising along in any gear above 4000 rpms and I am REALLY light on the throttle (basically it is barely open) then sometimes it will cut out and back in super quickly. It is especially apparent in the lower gears. I just went out in my driveway and just pulled the clutch in and tried to hold the rpms at 4000 or 5000 rpms...the tach would sometimes drop quite a bit and come back up. Any idea what is going on here? The bike pulls strong at larger throttle openings and there is no misfire whatsoever.
I hate working on bikes, I generally buy them to ride and that's it. The last thing I want to do is tear it apart and start replacing spark plugs, coils, etc. The bike has 15,000 miles on it and it's a 2007.
Thanks in advance!!
Here is some video of what it is doing:
