markspencer Posted September 5, 2011 Share Posted September 5, 2011 Hi guys im hoping somone can help i have recently upgraded from a pit bike to a DTR125, It starts and runs fine except one thing, when you pull off the engine wants to die sometimes it does sometimes it bogs down a bit then starts to accelerate, as soon as i am going about 5 miles an hour the problems stops and runs really well goes through all gears you can feel the power valve it is just when you get to a slow speed it wants to die. the worst is hill starts. it seems to get better after about an hour of running but hoping i can get thsi sorted. I dont know if it matters but it used to be a road bike all elctrics have been stripped and auto oil mixer removed too. if you need to know any thing else just ask, and thanks for the help.
