    Need Help 2007 Yamaha FZ6 no crank issue

    ordered a new gasket to see if thats the problem. im thinking when i tighten the bolts the cover presses on the idler gear causing it from moving. there is no evidence of rubbing anywhere in the flywheele or stator. will keep you posted

    Need Help 2007 Yamaha FZ6 no crank issue

    Just now took the stator and cover off the bike again and it started to crank. Now to see what’s going on. I put the cover with stator in without unbolting the cover to the engine and it cranks BUT as soon as i tighten a few bolts to seal it it stops cranking

    Need Help 2007 Yamaha FZ6 no crank issue

    I also have another good running 2007 FZ6, so I can swap parts between the two for testing. One thing I noticed, with the stator cover off it spins freely and even cranks and starts.

    2006 FZ6 – Dash Stuck Flashing "EP" (Won’t Enter Diag Mode, Works Occasionally)

    Thanks for the tips. I went through the battery, charging system, fuses, power, and grounds like you guys suggested, and that really helped me narrow things down. Here’s what I found step by step: Battery: 12.8–12.9 V key-off, holds strong under load. Charging system: New stator & RR, charges...

    2006 FZ6 – Dash Stuck Flashing "EP" (Won’t Enter Diag Mode, Works Occasionally)

    Hey everyone, I’ve got a 2006 FZ6 and I’m running into a weird electrical problem. The bike starts and runs fine, but the dash just flashes “EP” nonstop. I can’t even get into diagnostic mode when it’s doing this. Once in a blue moon, the dash boots normally (tach, fuel, speed, etc. all show...
