Greetings from Florida
My 2012 GT250 w/2000 miles lurches when going from on throttle to off throttle and back to on throttle when engine is turning less than 6000 rpm. The lurching makes the bike awkward to ride when in slow moving traffic, crowded parking lots, etc. Must constantly use clutch to counteract the lurches. Even using small changes in throttle position brings about a lurch. Bike also has flat throttle response below 5000 rpm. I mention this in case it is associated with the lurching but I do not view it as a problem. Bike starts & idles well and performs flawlessly above 5000 rpm. Its a joy to ride when in the Dr Jekyll mode but Mr Hyde is hard to accept.
There is no proper Hyosung dealer in my area so the repair will be a DIY project. I could really use some ideas as to where to start. Any suggestions would be greatly appreciated.
