My friends kdx is given me grief, everytime we go riding it plays up and he certainly wont do anything about it. Recently we were riding in the bush and the kdx just kept loosing power and then locking the back wheel and stalling. It didn't cease completely because we could start it again and ride for about 50m before it would do the same thing. If you kept the revs up it may have gone for a bit longer before it stopped again. We did notice that the it wasn't blowing any smoke. Could it be that the oil injection is blocked? If so, is possible to clamp the oil feeder line and just run premix, or do we have to remove the injection kit? any advice
