I was wondering what you guys thought.
I have a problem every time I cross train tracks. When I go to cross them the bike will stall almost every time and it never stalls any time else. I was wondering if it was possible that the jolt of going over the tracks was enough to cause the tip over sensor to engage and turn off the bike. It always starts right back up. I have crossed these same train tracks for years on my 400ex without any problems and all my friends with all kinds of other bikes have no problems either. It is very annoying and would love to come to a conclusion on this.

If it is the tip over sensor causing it has anyone bypassed the sensor?

Thanks

I bypassed the tip over sensor. There was nothing wrong with the sensor ,just didn't like the idea of it.

I doubt that the tip over sensor is your problem. That sensor only engages when you get to a "point of no return" on a side roll over... It doesn't engage going over front to back. Also, it's called a bank angle sensor. But, it could have come loose from it's mounting position and is being held in a funny position. You said your quad starts right back up... If that sensor had tripped, you'd have to turn the key to "off" to reset before your quad would start.

ok so if it is not the sensor does anyone else have any ideas as what may be my problem?

A possible loose electical wire? Hard jostle interupts the circuit. Do you jump the quad? How about then?

Dirty fuel filter. Sounds crazy, but very likely.

Well the quad is new and only has about 25 hours on it so I doubt it is a fuel filter. I have never really jumped the quad so I cant answer that either. All though in other rough terrain situations including going over downed trees I do not have a problem. It is very odd that I have only had the problem when going over the train tracks. The only other thing I can think is a low RPM lean stall, maybe a programmer will help adjust the fuel map so I does not stall under this condition. I hope to be getting the Big 3 next month so I guess I will wait and see if that helps.

Ba9801,
Sure sounds like the battery cable/s are loose. Runs great until it/they are jostled then you lose power after which it starts nicely and runs fine until the next beating. The batteries in these machines are not filled with electrolyte or charged until the bike is serviced after sale so the dealership may not have done a good job of installation.

Ok I will check that tomorrow.
Thanks

Ok I will check that tomorrow.

Also check the spark plug wire, if battery seams fine. Some have tore wire from trying to change plug when they can't get spark plug boot to come off easy.
