Mist the intake flanges with brake cleaner. If your bike’s idle drops, or the engine stalls, you have an intake leak. If this is the case, replace the intake seals along with the front & rear intake flanges. If the bike passes the intake test; have the dealer or your mechanic scan the m/c for possible codes.
