2008 Yamaha vx cruiser.
It started with a rough idle and stall problem but ran great at full throttle.
Then started running rough and would not go past 25 MPH, then finnally stalled and no start.
I have checked all the basics and it has no spark at all four coils.
Anyone seen this before?

Look for loose connections in and around the e-box first. Could be a bad pulser coil, but that is rare...........also a pain in the A to replace, since I'm pretty sure you have to remove the motor.

I'd take it to a dealer and let them run the diagnostic software before doing anything drastic.

Fixed!

Thanks for the reply, but problem solved. I discovered my spark tester lead was broken and what I had was 4 fouled plugs. I have seen numerous posts on the oil issues and did have some some in my airbox as well, I lowered the level and plan on adding a crankcase breather filter to the line to keep this from happening again.
