Stage6 R/T Mk II PWK Racing Carburettor HELP!

Baught my aerox the other day and it Boggs around 25mph like mad? Got a lot of body upgrades but has nothing to do with that and my engine: has 70 kit on I think and it has stage 6 manifold' stage 6 open air filter, c16 exhaust no baffles and Stage6 R/T Mk II PWK Racing Carburettor and I think that is my problem th carb not sure it's a 24mm and I think it's just to big? Any suggestions?

 

17.5 mm or 19mm would be better , easier to set up . But it might just need jetting properly

 

I would really prefer to keep the carb if i can, i took the two jets out the big one and small one (is there anymore and witch one do i change?) theres no number on the big one i can see but on the small one its has a 38 on it? what ones should i get? how smaller?

 

i up jetted it and it works fine just need find out why you have 3/4 throttle on to get it going now...

 

When you are starting it do you have the choke on correctly? Also, when it's on does it idle fine?

(edit)
Just re-read this, when you say "get it going" do you mean turning the bike on or actually moving it?
