Right, My clutch only has about 200 usable miles left. If I go from 1/4 throttle to full in a snap, the clutch slips for about a second.
this happens even at 3,500rpm and I'm only on a Suzuki GN250

Anyway, To the point.
Tryin to save a bit of cash so... Do I need to get the steel plates as well as the friction plates? they dont look blued on the edge (can see plates from my oil filler cap)
Also, would you say it'd be worth gettin new clutch springs whilst I'm at it?

And YES... I have tried adjusting the clutch... and changed the oil.

Any other pointers on gettin my clutch changed will be appreciated.

It will be taken to a garage for the labour to be done I just wanna know whats necessary for it (my mum wont let me do it myself and she's the one payin for it)

You need to strip the clutch and accurately measure both friction and steel plates, springs too. Wherabouts are you?

Oh, unless they're stupidly expensive, I'd stick new springs in anyway but both plates and springs have wear limits and you won't know if yours are near that until you/someone strips the clutch and measures them properly.

been quoted 41 quid or somethin for clutch kit and 9 quid for springs

Labour shouldn't be more than 2 hours top, should be just one hour really. Deffo replace the springs at £9 but you might get away with using the old steel plates.

Is that £41 for Suzuki plates or aftermarket ones?

aftermarket.
Suzuki ones were a lot more, like, rediculous
would that "Clutch kit" include steel plates?
From what I've seen a "Clutch kit" normally consists of a gasket... and friction plates only

Have you tried fitting a new cable? Many slipping clutch problems are caused by the cable.

trust me, cable is fine =P but how would the cable cause it? surely it would only cause it if the cable was too tight... which it's not. It has slack in it and is STILL slipping.

You'll have to ask the vendor that, could possibley be just the friction plates. I'd have a good google to make sure the ones you're thiking of getting are ok. I've heard people have problems with some aftermarket plates, inc EBC. Although the GN is quite tame compared to some bikes so wouldn't expect too many problems.

Apparently 20bhp... with a top speed of 75mph... Once again, Apparently.

It might not be - but worth suggesting Smile

Cables get gummed (or worn) and they don't move as freely. It doesn't take much to make a marginal clutch slip. A friend of mine had a superdream with a slipping clutch, I told him to check the cable and he bought another clutch, then replaced the cable when that clutch was also slipping.

If you can't freely push & pull the cable with your fingertips with both ends disconnected it needs looking at.

Could be just some heavier springs, or some packing spacers under the springs are in order then.

You could, but it might not help if your clutch stack is within tolerance but the spring free-length isn't.
