Has your bike got aftermarket cans and air filter? This engine is prone to "hunting" and these accessories seem to make this a bit more prominent. As a previous poster has indicated, doesn't really make any difference so just ride your bike and enjoy it!

more to check

I have an AE and the surging sucks when trying to take off smoothly. I have turned up the idle to 1100(book says 1000-1100 normal) and done throttle sync. I will put a few hundred miles with techron before doing anything else. Has less than 5k on it. All original and the filter is the original w/o critters. FYI- - I know sometimes a bad spark plug or spark plug cap can cause this symptom.....aka spark not steady
