I have a 1997 Yamaha Big Bear 350 4x4. It used to start right up. Then all of a sudden it wouldn't crank. I have a schematic for it so I started tracing the problem. I had no power at the starter solenoid. According to the schematic the power comes from the neutral switch and through the starter circuit cut out relay. I cannot locate the cut out relay on this machine.. If I apply power to the relay it will crank with the start button.
The neutral switch is hard to get to with all the brackets on this thing. I did find out from all my research that if I apply the rear brake lever it will start.
Does anybody know if the cut out relay exists and where it might be found?

I wanted to share a successful workaround for a "no-spark" issue on a 2009 LT-A400.
This is specifically for cases where the CDI has been diagnosed as faulty, but the age or condition of the machine makes the cost of a brand-new OEM unit hard to justify.
Note: This modification compromises the factory “no-start” circuits.
On some malfunctioning CDI units the internally damaged circuitry is only partial.
Feeding full time power to the Parking Brake pin, the unit is triggered to bypass the internal fault and produce a healthy consistent output to the Ignition coil.
The Modification
See the second diagram attached below for the wiring specifics.
The Result:
The machine has clocked over 1,000km since this repair and is still running strong with no ignition dropouts.
⚠️ IMPORTANT SAFETY WARNING ⚠️
Please be aware that this modification compromises the factory safety "no-start" circuits.
The machine will now start in gear. The safety interlock involving the handbrake is no longer functional. The machine can move unexpectedly if the starter is pressed while in gear. Proceed at your own risk. If you sell the machine or let others ride it, ensure they are fully aware that these factory safety buffers have been removed.

Can you put tracks on manual atvs? would it be effective? is 280cc enough to even move them? thoughts/suggestions?

So I decided to pick up a small trailer if I could get one for the right price. I found this one for a few hundred bucks on Craig’s list. It is a galvanized trailer which is exactly what I was looking for. The wood was shot and needed some minor repairs which I could care less about as long as the chassis was good.
I striped it down and put a new deck on. I had some vinyl realtree graphics that I had laying around so I added them to the fenders which I think worked out well. Very happy with this little guy.
I'm having the iron workers at my jobmake me up a few lightweight side rails that will have a 22 degree bend in them to accommodate the tires that slightly hang over the edge and will incorporate some tie down points as well.
