Hello all, I recently bought myself a 2009 Yamaha FZ-6 Fazer with 45k miles on the clock. It also has the dual headlight mod and a delkevic slip-on exhaust. The bike rides fantastic and sounds amazing, with plenty of power throughout the rev range.
Unfortunately, it has an issue in which the bike will randomly stall out in neutral. Once this happens the motorcycle will turn over, but not start, eventually displaying a code 12 error. However, after 3-6 attempts of cranking the engine over to start it, it eventually springs back to life with no issues, no active codes and a healthy idle. The issue only ever happens when idling and has never happened whilst in gear nor whilst moving. Idles around 1350rpm when warm.
So far I've tested the resistance of the CPS and TPS, both of which are in spec. I've replaced the bulbs for LEDs to reduce the load of having dual headlights on the battery, and also bought and installed a fresh battery. and the battery reads 13.1v when the bike is off and 14v at idle (likely due to less power draw coming from the more efficient LEDs). No blown fuses, and relays appear to work fine when tested in diagnostic menu. Fuel pump primes well and consistently. Kill switch has been taken apart, contacts cleaned, and reassembled.
I understand it's quite the strange issue, and I'm debating on whether I should have a motorcycle mechanic come and take a look at it. These forums have been helpful and informative however. I know it may be a difficult issue to diagnose, but any help would be appreciated. I love this bike and would like it to be with me for years to come, but the risk of it leaving me stranded from home has meant I haven't ridden it very much as of recent.
