Is it an automatic then?

[bazman]

Don't suppose you've cabled it wrong way , and it's in a false neutral between third and fourth?

Could the cables be just to tightly done up..?..once did some that was mega tight and having no handlebar slop..on starting up and just putting hand on handlebar it jumped in to gear.(a bit like a hairline trigger)..dropped em off a bit and was ok..?

Just a thought.
