@declan Wouldn't be a bad place to start.
An idea would be to see if it pulls fine with no load on the engine.
So first just put the bike on a paddock, start it and go through all the gears. If that works no problems then jump on bike and od the same but keep it part throttle only. No load.

@declan With load on the engine does it revs hard and no power. Clutch is slipping then.
Either adjust it or replace it.
-
@calum no it lacks power off the line when moving its decent shift into 3rd the revs die down to a slow idle and you go about 3mph
-
@declan Nah doesn't sound like clutch then.
Sounds like it's a carb setting.
Take the plug out and have a look.
Could simply just not getting enough fuel.

@calum ive been through it more times I can count and never found any issues it's spotless and as for the settings I wouldn't have a clue I'm guess it's way lean on the a:f screw but it turns off on command when hot using the choke

Sounds rich to me. Lean would cause a high hanging idle. The bike should still rev out, just without much power.
When rich, everything is sluggish, and going WOT can feel like youre hitting a rev limiter, or as if the bike has a restriction.
Have you done all the basics? Fresh plug and clean airfilter? Is your floathight correct?

You could remove the side of the airbox and do a testrun and see if its better or worse.
Dont think you can adjust the airscrew enough to sort this out. -

It's getting difficult.
When you start modifying stuff you're making it harder to diagnose the problem.
You really should only be modifying stuff when you know what you're doing.
If you're stuck, then I would revert it all back to stock and take it from there.

@declan Yeah, like I said. Get it all back to exactly how it should be. Then we can help to diagnose the fault.
It might be overshadowed by one of the many mods that have been done to the bike, hence why we are all struggling to come up with a single solution.
Or learn how jetting works. There is plenty of guidance on this forum for said information.
