Thanks for the ideas,only thing is its only just come off the rollers then all this starts! Gutted.Also some times cuts out at 4500rpm...its not chipped and running 10psi with magnex stainless straight through and piper x induction got baily dump valve on it too.Ive been recomended to have it chipped and as my tapets have got rather loud ive also been told to fit a new set but am thinking of goin straight for kent camm kit...just money is holding me back...damn crimbo never get back what i spend!!!!!
