I recently bought a 2015 Outlander-L 500 and the owner that i purchased it from said that his grandpa died and passed it down to the owner but he said that his grandpa had lower the top speed.He said that theres a screw under the motor that his grandpa used to make it top out. if you know what the screw is called or there’s a solution for this can you reply

 

the only thing i can think of is the screw on the back side of the thumb throttle... Since that machine is EFI their is nothing that i know of below to turn down
