1988 zx750 bad rattling through rpm

[PitRowGuy]

I have a 88 750 with this rattle throughout the rpm band. I have replaced the stock tensioner with an aftermarket manual tensioner. I have check that it has spark and it reads 5ohms on the incoming of the coil packs. new plugs and new fuel filter... I adjusted the valve clearance to the suggested setting and have put fresh fuel and fuel line in... I am at my whits end and would like some suggestions/help. I have a guy willing to look at it but cant see it til Jul 19th.



ANY help is appreciated...
