I have a Hyosung gt125 and takes the piss to warm up, after about 10-15 mins with choke on full, Wack choke off and try to ride and sounds like the bike is starving fuel, after a couple of pumps from the throttle it slowly comes through, could this potentially need upjetting or carb settings looking atβ¦.. it kicks in about 8k onwards and before that is slowly accelerates with the exaust making a crackling sound. Need help with fixing this as itβs doing my head in!!!
