Problems:
- Fuel light has been on nearly since I bought the bike. (4500 ish miles on the fuel trip.) I don’t think it’s a big deal, I mention it to give you complete information.
- O2 Heater Error comes on occasionally
- Communications error comes on the display intermittently
- Battery Warning on the display intermittently
- Battery Error on the display intermittently
- Battery died after the bike sat for two days (3 volts)
- I noticed that charge at the battery (with a voltmeter) is different than the “Battery Voltage” displayed in the Live Data screen (15 V on the display 14 V with a meter)
- With the bike running and my voltmeter attached to the battery, the voltage reads 14.1 to 14.3. Again… the Live Data screen will read 15.1-15.3
- Charcoal Can or Fuel pump “whirs” a lot. Like over night once a minute or some such.
- Radiator Fans stay on for a long time after the bike is turned of… sometimes up to 15 minutes.
- HIGH idle at start for several minutes (4000 RPM)
- Bike is lurchy at low idle, hard to control
- Bike dies frequently, 8 times yesterday in traffic, 100 degree day, bike had been sitting in direct sunlight for 8 hours.
Checks:
- I checked all grounds, front frame, rear frame, starter solenoid, and front cylinder. Fine
- I pulled the air box and checked for mis routed, melted wires leading to the 02 sensors. Fine
- I checked for draw. Negligible amount, less that 1A
- Stator checks out no shorts to ground and continuity between all yellow wires.
Actions:
- I pulled the fuel pump and replaced the sensor, turns out the float had come off.
- Replaced Reg/Rec (no change sent it back)
- Replaced battery
- Purchased a Shorai Charger
Notes:
This morning I ran the bike until th idle dropped from 4000 to 1800 The fuel pressure was at 480 the The Battery voltage running was at 15.3. The idle came down after 2 or 3 minutes, then the bike died. I tried restarting it 2 or 3 times and it continued to die.
With the bike off, I unplugged the fuel pump from the harness, the Battery Voltage dropped to 13.1 (what the battery voltage reads with a voltmeter at the battery terminals) I plugged it back in and up to 14.1. I am 80% sure it’s the fuel pump. I'm not sure how I can tell for sure, so If anyone has any handy fuel pump tests send 'em my way.
Thanks.
