I've got the dt125r manual & i know you have to set up the slot so that it's in the same place as the hole. But it seems to be cutting out when i stop :( ever since i had a topend rebuild. Carbs fine, everything else is fine jusrt think it might be the spark plug cap or the setting for the powervalve. All answers welcome thank you :)
Baring in mind that the dt125r can only go up to 55mph to 60mph. & beforee it had a rebuilt piston it was 80mph top speed! One of the adjusters is seized but i haven't messed with them & put them back ni the origenal screw size
