I recently bought a 2010 Hisun 700 UTV and have been having a heck of a time with the throttle cable and carb. I did get it to 38 miles an hour, but now its dropped to 33. Is that the full speed for this buggy? I am on my second throttle cable trying to find the correct length to make the speed consistent. I floor it, but it takes a good while to get up to speed. What is everyone else getting for speed? And any ideas on how to set the throttle cable or adjust the carb? Thank you!!
