ok I was either getting clutch drag or clutch slip ( at high rpm / speed ) and couldn't get a happy medium. I put in a set of bgm plates and MB uprated springs and this seemed to sort it for a while but started slipping again when warm if I hammered it. Ive also got some of the thinner 1mm steels and a thinner top plate. If I use a couple of the thinner steels and thinner top plate I reckon I can get another plate in there (5) and still have the required amount of free play when compressed but I would need to bend the ears of the top plate so as they sit in the slots of the crown wheel. Would it be ok to do this ?
thanks , Baz.

ps I don't have a lot of cash at the minute so im trying to sort it without splashing out on cassette type clutch or similar , I have a gt 190 kit that has had some work done on it , 30 mm delly an franspeed race pipe so would have thought a uprated 4 plate set up would be up to the job.

Forget the cassette clutch, you already have all you need. If you use a clutch compressor, tighten it down and measure the gap between the top plates with feeler gauges, if you've already done this, what the measurement?

at work, so might not have details exact, but......

normal clutch is
4 x plates at 3.5mm each = 14mm
3 x steels at 1.5mm each = 4.5
1 x top plate at 3mm = 3mm

Total 21.5mm

So within your existing clutch basket, this is what you would be aiming for as a total (21.5mm).

You can get 5 plates in, but ony if you go for the thinner 2.5mm clutchplates and thinner steels

Oh and remember its not precise, even when done correct measurements sometimes have to swap a steel or too.

You can mix and match !!

Good luck
