RDT20 Yes, check the battery. The FZ-6 requires riding and sustaining 4K rpms for the stator to recharge the battery (IIRC). Also, buy a battery tender, TRUST ME, it will be the best money you will ever spend. Idling will not allow the stator to charge battery. Not a lot of extra juice on the FZ-6, so if you have any mods or upgrades that are drawing extra power, the battery will suffer. My battery has died in the middle of traffic on a hot day sitting in traffic cause I didn't have it on a battery tender when I was not riding it.

Now, when I get done with a ride, I pull into my garage and connect my battery tender. I also have the dual headlight mod, tail light modulator, and garage door opener (flash to pass), all these place a drain on the battery.

Dominik How old is the battery?
Might want to check the voltage.
A bike stalling could be sign of bad battery.

FZ6 dropping idle RPM, won"t rev, no power, stalling, unridable, please help
Hello, This is my first yamaha motorcycle, bought it about a month ago, everything was great until one day was going home from work (everyday commute) and still everything was fine, came home, shut the bike off.
However, after an hour or so, I wanted to go for a ride, the bike started, but the RPMs started dropping until 650 when the bike stalls. Tried again, same thing, starts at 1250 then starts dropping when it eventually stalls. after it warms up it won"t start at all. when cold it will take a bit of throttle and raise the RPMs to maybe 3000 but anything more than that it bogs and stalls so the bike is unridable. I don"t know even where to start beacuse all the TPS issues are similiar what I have at idle but no one complained about a bike not having power and stalling under throttle. my TPS values in Diagnostic mode are 17 and 101 so I guess it"s fine? Is it possible it is just the TPS issue? Anyway, I want to fix it, but don"t know where to start since I didn"t see anyone with the same problem as I. Please help.
