Im desperate and really need this asap, Can someone please help me out.

Im trying to get a new twist grip for my Zing 250cc (pulse adrenaline 250cc)
But i'm being told different thing by different people and don't know whats-whats.

So i need some of you lovely people to go out to your bikes and take pictures of the twist grip / throttle area and how it attaches to the handle bars. would be even better if you could remove it to let me see exactly how it goes on,
but pics of it fitted should be fine.
I also need the same for the clutch area (light) switches to see where how your chokes fit.
Pics of mine below.

Brace yourselves for the wall of text.............................................. .................................................. ...................................

So the back story is this.
I bought the bike cheap with the intention of fixing it up to sell on.
Its a ex demo bike with only 1......yes 1 previous owner - the dealership ZingBikes in Huntingdon on the log book.
It only has 171.7 original miles on the clock so the engine is brand new. It was stored dry and as such only has some very tiny patches of surface rust anywhere on it.

But sadly at some point it has been stripped of a few bit (or maybe they were never fitted) like the Gear position sensor.
The air box has been messed with to fit a different battery and sealed off with a cone filter fitted to the carb.

Its biggest issues are the handlebar areas. The choke cable guide is broken and the throttle twist grip looks to have been cut off.

Now i'm being told by some that the twist grip is separate from the switches and also by others that its attached to them so would need to buy complete switches to fix'
And im being told that the 125cc dont have a choke on the left switches only the 250cc do??
Also being told the handlebar gear is the same on all these chinese bikes and then being told its different between importers and what engine is fitted...........Head ache
I really need to clear this up (with pics) so i know what i need to buy to fix it.

Heres some pics of what i mean.

(or maybe no pics as it wont allow me to upload any.

Thanks for your help folks.
