Default 1994 clutch will not engage

Hello to all and hope someone can help.
I own a 1994 Cbr 900 sc 28 I’ve been doing an overhaul and renewing loads of parts as I’ve not ridden it in over 5 years.
list of new parts below
fork oil / fork seals / fork dust seals
stator
regulator rectifyier
chain and sprockets
new tyres front and rear
brake pads all round
brake fluid front and rear
rear sets
leaver
choke cable
Accelerator cables
carb overhaul kit
battery
led indicators / led relay
x2 one way diodes for led indicators
air filter / oil filter / fuel filter
metal brake lines front and rear
bulbs all round
x4 new spark plugs
x2 new coil packs
renthal grips
r&g bar end protectors
r&g frame protectors
complete ss exhaust system with carbon devil back box
last of all a new clutch kit and cable

this is where my problem starts 🙈
so I soaked the new clutch plates for 24 hours
installed the small seat ring washer first then the judder spring, yes the judder spring is installed the correct way round, then the first plate which has a larger internal diameter, then metal spacer then carried on with the rest as per normal, fitting the last plate into its different recess and then fitted the cover plate and then the x5 new springs / washers and nuts, all torqued up to correct torque setting. Then put back on outer clutch cover and filled the bike up with oil and refitted the new clutch cable, leaving a mm of free play in the cable, bike starts Loverly and sounds great but the clutch allows you to select a gear but then slips like a mo fo and won’t pull away ? Please help as it’s driving me crazy. I’ve now re drained the oil and removed clutch housing and re checked the whole clutch again. As above everything is in the right order and judder spring in in the correct way around, bought new engine oil and tried again, same again no joy and she’s slipping like before, I did put it in gear up against a wall and revved it up in first gear hoping that the clutch would engage, did this for short 20 second bursts and it enabled me to gently pull away but then more slippage, it seemed like the more the bike was ridden past the slippage it pulled a bit better but then if you gassed off and stopped and pulled away from standstill it just slips again. Any advice would be gratefull to try resolve this issue. Oh by the way the new exhaust sounded wicked. Lol
so desperate to go for the mot and a blast
PLEASE HELP 🙏🏻

1mm of free play on the cable doesn’t sound enough, do you mean at the engine end or the lever end, I’d expect 3mm at the lever end, also even if you have free play at the handlebar lever the cable could be the wrong one or jammed, so always check that the actuator arm isn’t being held in tight at the engine end, the exposed inner cable should feel relatively loose when the clutch is out, I think your problem lies elsewhere but at least the above is a quick check.
