When throttle gets wet, it will cause the engine rpm to drop dramatically or even stall. You have to come to a complete stop, shut off everything including key and kill switch, then restart. KTM is aware of this but has delayed for several months sending out replacement parts even though they sent a letter notifying me that it was a recall. Your system doesn't show any recalls when there is. KTM needs to send out parts now and your system needs to acknowledge and list this recall.
