Sounds like way too much air. Tell me does it sound quite deep when you rev it.
In neutral after its warm, when you blip the throttle does it respond instantly.
Like this numpty here
Says aww 99 octane fuel killed my bike. Uhmm no mate, you can clearly here the snorkel is not in the air box. Clear as day. I don't understand why people remove them lol

Make sure the snorkel is in there and that there are no sharp turns in the inlet Tracy. It's the bend into the air box that stalls air flow. Hence why snorkels are a must.

ok had another play today got it running a little better screwed the choke cable right in which made it pull off better still a little lumpy at about 20 to 30 mph gona try a new air filter which might help , tried running with no filter just the box but that didn't help made it worse at least it can pull away now will have to try more once its run in , a few pics of the air box set up and the plug , does the plug look normal ?

how it runs now -
Cool, snorkel is there. If taking The filtration out makes it worse, then it's getting too much air and not enough fuel. If you max out the idle screw movement then you will need to go up a jet size.
I have posted a carb tuning tutorial on this forum that will help sort it.
If it runs fine with wide open throttle, then you can leave the main jet well alone.
