the inlet cam is too far advanced by 1 tooth. There should be 12 pins between the 12 O'clock marks on the two cams, assumeing it's a YZ cam and you want YZ timing. Also the 3 O'Clock mark on the inlet cam should be level with the head surface (or slightly below due to chain stretch). The 9 O'clock mark on the exhaust cam should be level (or slightly above due to chain stretch).
