Bike movement weird

Help and Feedback Scripting Support

Hey guys, so for some reason my bike moves weirdly. Like when moves according to worldspace not local orientation. My goal is to move the bike towards the front

Note I have to use Right Vector due to the way i sized my Body part

Code:

local timeForSpeedUpAndSlowDown = .5 --Seconds

local seat = script.Parent.VehicleSeat
local FWheel = script.Parent.FWheel
local body = script.Parent.Body
local LinearVelocity = Instance.new("LinearVelocity", body)

local attachment = Instance.new("Attachment", body)
local attachmentAngle = Instance.new("Attachment", body)
LinearVelocity.RelativeTo = Enum.ActuatorRelativeTo.Attachment0
LinearVelocity.Attachment0 = attachment

local Gyro = Instance.new("BodyGyro", body)
Gyro.MaxTorque = Vector3.new(1,1,1) * 100000
Gyro.CFrame = body.CFrame

local CF = FWheel.Weld.C1

while wait() do

    LinearVelocity.VectorVelocity = Gyro.CFrame.RightVector * (seat.Throttle * -100) 
    LinearVelocity.MaxForce = (body.AssemblyMass * LinearVelocity.VectorVelocity.Magnitude) / timeForSpeedUpAndSlowDown  
    Gyro.CFrame = body.CFrame * CFrame.Angles(0,seat.Steer * -math.rad(10),0)
    
    FWheel.Weld.C1 = CF * CFrame.Angles(0,seat.Steer * math.rad(10),0)
end
