having to screw it nuts off, help

 

If it's got a race clutch in it, the springs might be too hard; and so you'll need softer springs!

 

ta for reply how do tell if its a race clutch last owner said he didnt do anything to it,
was before he bought it what ever was done

 

Take it out, it should be branded. Does you're back wheel turn straight away? But doesn't engage straight away. Your clutch could be slipping

 

how do you tell that clutch is slipping, just load of revs and you go nowhere

 

You'll be able to feel it. If its a standard clutch, the springs might need replacing. Try and get a video of you riding it? It's much easier to judge
