Default Curvy gearbox problems

Long time no see. Partially because my SV has been off the road for a while now, but I want to get it on the road again.

I've got one problem i'm not sure where to go with. With the bike running, I cannot get the bike out of first. When starting it from neutral, I can go up through second third etc. and back down again, but its a little stiff. If I then go down into first it ain't coming back out again, until the engine is stopped.

back story all included as may be relevant(?):

It dumped all its oil onto the road a couple of years ago and seized. In the mean time, I have stripped it, got the crank and main bearing sorted, and rebuilt. I had it on the road for its shake down whilst still in its old MOT, and it was perfect for 10-15 miles, then clouds of smoke. New job/New wife meant it took me 6 months to hunt down the issue (cam chain tensioner had cracked at the mounting bolt and was weeing oil onto the exhaust, sorted) bike start and seemed to ride fine. New oil at this point. and booked MOT. Once it was warmed up clouds of smoke again so cancelled the MOT. Then didn't do much with it for a year, as I had a gixxer and life got in the way. I want it back on the road now and I think the smoke was just the oil not being burned off previously. Doesn't seem to do that now anyway. I put new oil in again, probably back in Jan, but have only started and warmed it up a few times since then (again life - gixxer and a now sorted brake issue). Once I had the brake issue sorted the gearbox issue has now come up.

what i've done/checked:
little plastic cover off the clutch/gear lever area. Its spotless, cos its only done 15 dry miles since a full rebuild.

There is a small amount of play (half a mm) in the selector stalk in and out, not sure if this is normal.

I've taken the oil filler cap off and the clutch sounds a little sticky when I pull it. I am not 100% sure there is not still some grease from the rebuild still in the oil mix, though there have been 3 changes since then.

Checked/adjusted the clutch cable, biting point is just after the initial pull, well away from the bar.

What would be the next things to check?
