Throttle Help!

[3WheelsOva4]

I have a twist throttle on my yamaha and i want to change it to a thumb how do i go about changing this??

Depends on which yamaha you have.Most yamaha throttles will work.You will have to get the correct throttle cable though.I have a thumb throttle from a yamaha warrior on a tri-z.It would help if we knew the bike you want it for.
