Hi, I have just bought a 2nd hand daelim VL 125 that clocked around 13500km. The bike is ok except it requires 5mins or more to warm up. The engine will stall immediately when I engage 1st gear if warm up is not sufficient. I don't have this problem when I rode my previous bike (Suzuki maruader GZ125). I can engage 1st gear and go immediately after I started up the engine. Is there any solution to overcome the long duration warm up?
