Hello, I have the following problem with my hyosung gt 125 r e3: If it is cold and you accelerate it does not pull properly up to about 8000 u/min afterwards it pulls for a short time better to then have power loss again. And sometimes at first it drives very slowly max. 100 kmh and pulls about 5-10 minutes very bad. In the morning after 2-3 minutes warm running I still do not get up the hail in the village, and from the village it drives at first only about 70 kmh. If it is warm however (morning after 15 minutes drive, or in the afternoon when it is warm after 5 minutes) she drives very well pulls and drives almost 140 kmh. Today it was very bad at about 10 degrees and rain I turned off from the work on a two-lane road in the inner town that goes there slightly uphill, there is 60 and I only got the first hill at 50, then it goes for a short time grade, then it has become better, and then when it went up again, she pulled almost as well as normal. he only starts with choce and runs the first time only with it, if I take it away too soon it goes off at the traffic light. In addition, the engine turns sometimes faster times more slowly and runs quite restless. Even if I hit the handlebar completely to the right it suddenly gives quite gas (ca 4-5000u/min) and if it has hit completely to the left it does not go at all. What do I have to do to get that into the grip? Air filter I once cleaned up, but it looks good but is from 20 09 and has been running since about 5-7000 kilometers. is that still ok or should I change the time? Carburettor to synchronize and clean up I do not dare myself. Should I have the carburettor cleaned and adjusted? Otherwise I have no idea what else I can do. I hope you can help me… Mfg Felix
