just got a 2003 dt125 r nice looking bike 6500 miles on clock. starts great but seems to be chocking itself to start and the when warmed up splutters at 6000/7000 then ok at 8000 what could be the problem?
My first point of call would be to change the spark plug.. As it's easier then fiddling with the carbs. Plus the spark plugs are known to need changing regularly due to it being a 2 stroke.. If that doesn't work then you better give the carbs a once over too
To the OP, please use the search function, this issue has been covered a few times before! Cheers :)
