Hey all, 2007 Hex Head with 78k miles. I've noticed lately that when I'm going along at highway speeds and whack the throttle wide open, like to make a quick pass, the power actually drops by about 10%. If I roll it open, it accelerates, however it still hesitates, but a wide open whack is a big drop.
Also of note, its far worse when it's hot outside than when its cool. Or if the bike isn't hot yet, it's not nearly as bad.
The bike accelerates great through the lower gears. Here is a list of recent maintenance
Spark plugs
valve adjustment
alternator belt
all fluids
new fuel pump
The bike also has a EJK tuner on it, which I've tried adding and removing fuel at WOT, plus completely disconnected and test ridden without. Same problem.
The next step I'm thinking is coils. Any other ideas?
