How often do you drag? You might have a smoked clutch that isn't putting all the power to the wheel at high rpms. Or you might want to do a compression test and make sure that you haven't done any motor damage with a too advanced ingition. You have to start somewhere with diagnostics. Giving 1 ET from the 1/4 doesn't really help without comparison, what are your times on a good day? How much time have you lost? Does you bike still launch normally? Do you notice this problem on the street as well? Are you running pump gas or something stronger like an oxygenated VP fuel?

If you give more information, we might be able to give more help.
