Brilliant cheers for the help fellas, I'm hoping to get down the machine shop on Friday and see what they can do for me. I'm going to be getting it all chemically cleaned any way and valve stem seals will be replaced to. Whilst I remember, socks what clutch/ fly wheel set up are you running as any set up that can handle the power yours is putting out is definatly worth investing in? Edit: also idrees can you get the valve spring caps? Just had a look over mine and I'd say they need replacing to.
