I don't think its going to get fixed until they redesign that bottom end. I really think they sacrificed a lot to get this engine extra light and the e-start is the biggest example. It just doesn't seem to have the "oomph" to conquer the engine compression on a regular basis. Does any other manufacturer use a worm gear style starter setup on their four strokes? It just doesn't seem adequate.
I agree...the design is marginal and any manufacturing tolerance may add up the wrong way.
The old starter system clutch was splined to the crank...this one is added behind a regular morse tapered flywheel....it looks like a 2 stroke re-starter on a KTM and I don't think it has the capacity to push over a hi compression 4 stroke all the time.
That being said my 2010 TE250 is starting/running GREAT with a bit of tinkering.
