Fast Bike in MTA

[Hellioob]

Hi! I need a script for multiple clicks of bikes NRG-500:
It's about MTA! there is a bike when I drive with it and I want to speed up more i need to press several times num9, the faster you press num 9 speed is increasing.
I found one but it does not work on MTA

; fast bike

~w & 1::
setkeydelay, 60
while (!getkeystate("capslock","p") && !getkeystate("space","p") && getkeystate("w","p"))
{
send {up down}{up up}
}
return

Can anything be done?
Thanks in advance! Sorry for bad English i are use google translate.
