Hey guys and gals. I've been working on my friends 2007 big bear IRS. Unfortunately after 3 different people got their hands on it and only made things worse every time. After months of finding just crazy problems everywhere. I'm finally at the point we're its almost 100% !!! But I'm getting a short somewhere between the 4xW switch I believe. I managed to by searching the internet like a fiend, got my hands on an official Yamaha wire harness for the year and make. But I don't have the numbered component list and to be honest. After hours of going through and making everything so it's easy to reference. If anyone has a picture of the referenced components. I would be forever in your debt. I've spent hours marking up the blown up diagram so it will be easy, for any possible future repairs. Please and thank you. Here's a picture of what i have so far. Unsealed it in plastic so oil and crap won't spill or get smudged. This damn things worth it's weight in gold. Thanks Jeff 2007 Yamaha big bear 400 IRS. YFM40FBW

I have a 1993 Polaris Trail Boss 350L 2- stroke. after about 200 yards or so of driving the motor boggs down.....it will stay idling but if I floor it, it will die.....if I turn it off and wait a few minutes I can turn it back on and go like hell for another couple hundred yards.... I thought the pilot might be worn out(I have it nearly closed now)......maybe the choke plunger isn't sealing or the Bowl isn't filling quick enough.....any suggestions would be appreciated.

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.
