As the 2025 ATV Motocross National Championship Series (ATVMX), an AMA National Championship, got underway with back-to-back Florida AMA Pro only events, it was evident that Phoenix Racing Yamaha’s Joel Hetrick picked up where he left off last season.View the full article

Just picked up a 2008 Big Bear 250. It was sitting for about 1 year it's definitely a project. Currently chasing down a no spark issue. Imagine that lol 
Tons of info around the forum. I look forward to learning! 

I have looked at every thread I feel like, but with no resolution. Its always the same with a no spark issue: 
Replaced CDI, 
Replaced Pickup Coil (Pulsar)
Good continuity from CDI to green white wire at ignition coil.
No Pulse at ignition coil on the green white wire. (testing with test light on Pos of battery.)
Good 12+ V on the hot side of ignition coil.
I swapped the wires around on the Pulsar.
The grounds seem to be good for the blk/y wires throughout bike.
Brand new battery.
Brand new stator and Pulsar
Tried 2 new CDIs
Brand new rectifier
I get about 300 Micro A/C volts across the two wires on Pulsar when cranking.
I am currently cleaning the connections on the rectifier because they were burnt. I am not even sure if it makes a difference because I am told that doesn't produce spark anyway and is only for charging system.
The fly wheel looks OK, is the pulsar supposed to be connected in the direction with the metal "Button" facing towards the flywheel?
My bike is a 1995 bayou 300, but I seem to come across same issues on web but no resolution on these things.

as title states, what are these wires?   I took off the rear plastic, and right behind the brake light, these wires are all disconnected.  Not sure what they go to.  Aside from my current issue of what appears to be a bad coil (replacement ordered) the atv has run fine for me.  I just bought it this past winter and spent time replacing front end components but motor has run fine until the this past weekend.  By the looks of these wires they've been unplugged a while.  only thing I can think of is they're for trailer lights maybe....?  but i really don't know.  

We know of a number of places to ride atv's, but does anyone know of a good place that has atv racing in the Northern Illinois area?
