When they pop out the revs can obviously rise, then they might pop back in, might not. So technically the gear is not slipping, it is the drive dogs disengaging causing the problem.
Would that not result in a noise as it slipped back in as the gear would be under load, such as a clunk or a bang or something. Or a rapid rise in revs as opposed to a gradual one. Not trying to be a smart arse just want to be equipped with as as much knowledge as poss before deciding which way to go with repairs.
The other thought I've had on this was could it be the tyre spinning up, as they were pretty cold. I got a real crappy Bridgestone on the back that was old OEM stock I had to buy in an emergency when I had a flat at Tenterfield. But that wouldn't account for the juddering in 1st when cold
