OEM bike problem

[doskata]

Hello!
I really need to know why does my bike doest the following thing:
When I join a map with a KTM 450 (OEM bike from MXBmods) and fall several times the bike starts acting up.
When I press the gas ONLY it starts to go sideways and when I turn left it just starts spinning making donuts.
Also when I try riding (after ive fell several times) I go forward then the bike strats drifting ALL BY ITSELF and then starts doing 360s and then my rider falls. but when i am on a default bike (for example MX 1 or MX 2) there isnt this problem! And also when i return to pit and press start the bike is not having any problems until i fall several times again! Please I really need a response so I can know where the problem is! Also although I have automatic shift ON when the problem starts the bike just doesn't want to shift properly
