Thanks to all the help offered i solved the issue it was the cables not turning the valve the right way it was closing instead of oppening , tomorrow im gonna do a topspeed test thinking of hitting atleast 120-30 kmh
I think the main thing are the piston rings bedding in.
I haven't worried about it too much. 50 miles if it's just a top end. But I am quite happy to rebuild the engine prematurely.
@SpookDog I'll inspect the power valve from the exhaust port and try to post pictures later, just to be sure
The bike feels fast and has good acceleration so there's a possibility that it's just my speedometer that's screwed up LoL
