It goes through the cleaning cycle ok when I turn the ignition on, but does sound lethargic doing it. so that would be a new servo/motor thats needed? To be fair I've not tested the battery either, so not sure what kind of condition thats in. That could affect it too couldn't it?

PV cables are all adjusted, holes line up etc.

@Pablo13 Yeah but on some CDI's it will retard the valve at certain RPM.
That engine should rev out hard all the way to the red line.
The best way to eliminate it not being the powervalve is to align the valve up through the exhaust port, then disconnect the servo. And take it for a test ride. Bottom end should be lost, but past 6K it should pull hard to 12k

So, check the green black wire is grounded and stick a finger in my exhaust is the next port of call?
Cheers for the help btw guys

Its not the valve. I took the exhaust off and aligned the valve, unplugged the servo and it was still the same at the top. What should I look at next?

Have you done a plug chop? What's the fueling saying? You running snorkel in or out? How old is the spark plug. Is it the correct plug?
How old is the ignition system?
Is the air filter clogged up?

Yeah still going flat in the higher rpms. Maybe the coil is weak. No plug chops yet, but I stuck a new one in a few weeks back ngk 8 i believe. Also along with a new air filter as it just ticked over 24km.....about 15k miles. Snorkel is in. Problem has been there before the service too. Would be nice to get to the bottom of it

Just an aftermarket exhaust and a 240 main jet I stuck in, that's it. So compression test next?

Most manufactures stipulate sticking with 210 main jet, despite the uprated exhaust.
I don't know the figures that constitute acceptable levels for the compression test.
I would look at the electrics first.
If the engine sounds sweet, then chances are it is.

Rino Racing or something similar the exhaust is.
So check over the coil next?

@Pablo13 Yeah something isn't right. But 93, if it's the original electrics, then I'd swap out the coil, and HT lead for a new one.
If it's still causing issues then it can only be the CDI, pickup or engine.
Unless someone else wants to chime in, I can't see what else it could be.
The fueling shouldnt be far off.

If it's running lean or seems to be at high revs, there are five simple things to try.
Float level, is it getting enough fuel?
Tank cap, is the vent blocked or partially blocked cause fuel starvation?
Fuel tap, is it opening fully and is it and it's filter clean?
There is an inline filter in the brass pipe in the top of the carb, is it blocked?
Air filter, is it very dirty or over oiled as too much fuel is as bad as too little?

All good ideas there thanks
Float level was set when I changed the needle stop as it was pissing out fuel from the carb when I got the bike, but sadly the problem was present before.
Tank cap Is a good shout, Ill take a look at that and the filters once the fuel level gets lower.
Air filter is new and not particularly over oiled, but again its been doing it with this one and the previous filter so can rule them out.
Ordered a new coil, HT and cap anyway. Possible the one on the bike is 25 years old, so cant hurt

Should also add that the bike revs freely to the red line when in neutral with no load.
