How do I change the speed of this snowboard? (edit)

I looked everywhere in the script to see what affects the speed but nothing worked

local Board = script.Parent
local Controller
local Gyro
local CoastingAnim
local KickAnim
local LeftAnim
local RightAnim
local OllieAnim

local OllieHack = script.Parent:FindFirstChild("OllieThrust")
if (OllieHack == nil) then
	OllieHack = Instance.new("BodyThrust")
	OllieHack.Name = "OllieThrust"
	OllieHack.force = Vector3.new(0,0,0)
	OllieHack.location = Vector3.new(0,0,-2)
	OllieHack.Parent = Board
end

local lastaction = nil
local lasttime = nil
local jumpok = true

function didAction(action)
	lastaction = action
	lasttime = time()
end



function onAxisChanged(axis)
	Board.Steer = Controller.Steer
	Board.Throttle = Controller.Throttle

	if (Board.Steer == -1) then
		print("Left")
		--CoastingAnim:Stop(1)
		KickAnim:Stop()
		OllieAnim:Stop()
		RightAnim:Stop(.5)
		LeftAnim:Play(.5)
		didAction("left")
	end

	if (Board.Steer == 1) then
		print("Right")
		KickAnim:Stop()
		--CoastingAnim:Stop(1)
		LeftAnim:Stop(.5)
		OllieAnim:Stop()
		RightAnim:Play(.5)
		didAction("right")
	end

	if (Board.Steer == 0) then
		print("Straight")

		KickAnim:Stop()
		LeftAnim:Stop(.5)
		OllieAnim:Stop()
		RightAnim:Stop(.5)
		
		if (lastaction == "go" and time() - lasttime < .1) then
			
		end
		didAction("go")
		--CoastingAnim:Play(1)

		
	end
end

function enterAirState()
	-- gyrate towards vertical position for better landing
	Gyro.maxTorque = Vector3.new(100, 0, 100)
	jumpok = false
end

function exitAirState()
	-- turn off gyro
	Gyro.maxTorque = Vector3.new(0,0,0)
	jumpok = true
end

function enterPushingState()
	KickAnim:Play()
end

function onMoveStateChanged(newState, oldState)
	print(oldState)
	print(newState)
	-- do state exits here
	if oldState == Enum.MoveState.AirFree then exitAirState() end

	-- do state transitions here

	-- do state entries here

	Gyro.Parent = humanoid.Parent.Torso
end

	if button == Enum.Button.Dismount then
		Board.ControllingHumanoid.Jump = Controller:getButton(Enum.Button.Dismount)
	end
