Vehicle Physic Issue

I have a script I'm using in a motorcycle. It handles good but when you bump something it will stand on the front wheel and spins. I've changed all i can think of with no noticable effect on it. Any help would be very appreciated.

any chance you could post the script or, give alittle more detail on the problem?

EDIT:
forgot the mention, sometimes the way it is buildt can affect the way the objects react, sculpies for instance have a inv box around the object, and other times, way objects come in contact can affect it also

Well the script is almost 700 lines its a little to much to put in here ,but when you hit something the back wheel lifts off the ground till your facing straight into the ground then spins around eventually coming back down to the ground.Is there something not set right that would kep the bike down on the ground?

it maybe a mass issue, try a large invisable prim as the bottom of vehicle like a skid

Micheal your scooter has its thrustline set to high. Its pushing through the center of the root prim which is higher than the front wheel contact point when it hits something, ergo over it go's. Use this line to lower your thrustline, and make it an instant hill climber )

llSetVehicleVectorParam(VEHICLE_LINEAR_MOTOR_OFFSET,<0.0, 0.0, -1.0>;

Enjoy

I could be the center of gravity is higher than the front wheel. Just like in RL, if the front wheel of a motorcycle hits a fixed object, it is going to flip ove teh front wheel.
