I’m having problems with my bike. It starts fine when cold, then after riding for thirty to forty five minutes the speedometer quits and then it will die riding down the road. I have put a new battery, new regulator, and new stator on it. Stated it up and thirty minutes later it was dead on the side of the road. I didn’t have any problems until I installed the Bluetooth speakers. I raised the gas tank up and put all wires under tank but did not remove the tank. I wired the Bluetooth directly to the battery. After the first time going dead I removed the speakers. This is when I replaced everything. it starts fine after sitting for a few hours but will go dead after riding 35 minutes. I checked and the battery is charging when idleing and when I rev it up the meter will go up to 14.2 sometimes 14.3. Does anyone have any ideas what I can check.
