hi i race gncc and i'm having a problem with my thrumb going numb during a race and i was told to cut my spring in my carb so that the throttle isnt as hardf tp push ws wondering if anyone has done it and if so how much do i cut

Take the spring out of the throttle housing and install a TRX90 thumb lever ;)
