Awesome bike but the battery is an issue and I’m chasing a charging problem at the moment 24 hours on the bike and I’m on battery number 3 there not cheap

I have 14.3 volts at the output of the regulator rectifier but not seeing at the battery itself 🤷‍♂️ Broken wire or bad harness. Shouldn’t I see the same numbers on both ?

Sounds funny but if I rotate the kill switch almost pointing down it doesn’t die 🤷‍♂️😂 I ordered a new kill switch and just threw an anti gravity battery in it. 3rd battery in 24 hours of life kinda missing a kickstarter and a carburetor at the moment ... more »

It was the battery Yamaha gave me a new one but I had to pay for diagnostic and install so if your bike dies just put a new battery in it. The warranty usually won’t cover battery issues I’m happy to help support my local dealer but two weeks without ... more »

Would that make it just die on the track though this is my main concern I understand the battery not turning the engine over but why did it just cut out and die

Rode 3 laps today the bike has 20 hours it died like it ran out of gas and won’t even try to crank over now anyone else out there experience anything like this. Hopefully the warranty covers it but still curious as to the cause
