150cc Chinese ATV dies when I steer
 

As the title suggests, this thing dies when I steer full left or right... Anyone have any ideas?

UPDATE:
I have deduced that it dies when it's shaken from side to side.

When it dies, does it falter, cough, sputter and die? Or does it shut off like someone turned off the ignition switch?

After it dies, does it immediately start back up, or is it hard to coax back to life?

If instead of shaking it side to side, what if you just jack up one side or the other? Does it still die?

What happens if you leave the quad still, but get in there with you hands and start moving all the wiring around? Do you find any wire bundles that kill the engine when you mess with them?

It dies as if the ignition were cut off, and won't start back up for an extended period of time. It has a very simple electrical system, and I haven't found anything wrong with it thus far.

So when it dies, and during that "extended period" when the quad doesn't start, do you have spark? Do you know how to test for this?

The idea here is to separate ignition problems (electrical) from mechanical or fuel problems.

I checked the spark, and found that my kill switch was broken. I fixed it, but the problem persists, causing a stumble now, instead of dying.

just a thought that happened to me on a Linhai quad: i had a kill wire twisting whenever i turned the handlebars either way. the wire was located on the downtube near the fuel tank.
