So I've got the powervalve sorted it's free as a bird and working nice by the looks when giving throttle but the top end is shocking. Seems to be break8ng down once band hits. Spat a plug this arvo so thought it was that. I nearly burnt it at this stage. This b8ke has been nothing but problems. Basically everything in the top end is less than 10hrs old. Edit the only th8ng ive changed is the head. Ive put an S3 high compression head. Besides a new stator as the old 1 was cactus. Here is a vid of it stationary.
