Hello everyone, New EM owner here, picked up a used 22 epure race couple weeks ago. What a fun bike, been having a blast with it. Although I have one issue that I cant figure out, went through this forum and haven’t seen a similar issue. When riding the bike for a bit randomly it will start to hold revs sort of similar to if the TKO is turned on even tho it is not on. If I hold in the clutch and release the throttle the revs will very slowly come back down very similar to a lean condition on a ICE bike. But With no clutch engaged the bike does not pull or want to inch forward. It will do this in all 3 maps. Then after a little while of this if I pull the kill tether and reinstall it, the bike will just make the map switch tone over and over again non stop. I can change maps but the throttle will never come back to life. I can turn battery off and on and still the tone keeps going. I have to turn the battery off and let sit for 5-10 minutes and then it will start working normal again. I have done the recalibration deal of holding map switch for 10 seconds and the rear wheel spins 3 times but after its done the tone just keeps going. Im guessing it has to be a throttle issue? Its the domino throttle. The wires look fine, connection at the plug is good, wires dont pull tight when steering lock to lock, throttle housing isn't beat up and throttle tube turns nice and smooth and snaps back quickly. But im guessing it has to be something wrong with that throttle? Oh and bike is not equipped with the PRB lever. Just wanted to see if anyone has an opinion before I go spend $200 on a new throttle. Any help is much appreciated. Thanks
