Reply To: Gv 125 top speed
Hi I was wondering if there is any way of squeezing more top speed out of a 2016 hyosung gv 125 I have put a 52 tooth sprocket on the rear and looking at a 16t sprocket for the font but is there any thing else I can do to it eg different jetting in the carbs or is there any ristrictions within the motor? I spoke to a machanic who said any tuning wouldn’t be worth it and it would more than likely blow up, is this the case?
