So, last time i got to ride the DT was mud running though slush, on my way home on the road, my bike lost all throttle reaction and just started redlining, now everytime i start it it redlines, ive spent about 12 months trying to fix it, cleaned the carby, air filter, checked the throttle cable isnt jammed up, but it still just redlines as soon as i start it, i had to ride home using the kill switch so i could slow down because all it does is go flat sticks
