It should slip through pretty easily,but if it's clunking and clashing you'd better learn how to it properly.If you are having a lazy ride use the clutch....if you are pushing it you won't have time.just flick it through.

Ooh this can of worms.

It is all ways best to clutch.

And I would say that changing up when not under power like you are doing is OK as well.
If you can time your down shift's when your rear-wheel is in the air you are OK as well.
When I raced my KX250 (97) for two years and only used the clutch at the start and the end and at hairpins corners and if the revs were down I just stomped it down and my gear box was OK. (touch wood)
But I would not like to say that it the best thing for it, but they seem to handle it.

One way of doing a good shift down is to put a little weight on the lever going in to the corner, power just off and not braking and it will when it's right it will some times just pop down a gear, and that is when the load is off the gear box and it's all loose and free in there.
