Multi-Sit on a Motorcycle

I have a motorcycle I built and a purchased script in the root prim of the bike that takes care of sitting the av on the bike and also allowing the avi owner to drive the bike using arrow keys and other keyboard keys for other functions.

I would like to customize things a bit in that I would like to use something like the super cool multi-sit product that's available so that once any rider sits on the bike they are given the option to adjust their avi on the bike so that they look right with regard to hands on the handle-bars, rear-end on the seat, etc...

When I add the multi-sit scripts to the root prim of the bike the bike tends to veer off to the right when you drive it. I'm assuming that's because both the bike script and the multi-sit script script have code in them that do things like llSitTarget, llSit, llUnsit, etc... and some of these commands are bound to be stepping on each other.

Can someone give me some idea what specific code needs to be removed from the bike script so that the multi-sit script is free to "do its thing?" I know I need to look at commands like the ones mentioned above, but also what about the llChanged event and trying to ask for permission to animate my avi?

Thank you for taking the time to read and consider this post.

Sincerely,

i dont see how the sit script can effect the vehicle script unless you rotated the root prim
