Cam chain tensioner springs

Hi everyone , Im new to the site and to VF 1000 ownership . I have a shed find 85 VF 1000 F with side car fitted . Ive done all lotto get it running and ridable , just , but find the cam chains are noisy . I want to replace the tensioner springs to start with but can find anywhere In Australia that can supply them.
Can anyone here direct me to a supplier who cold help me out ?
Thanks in advance for any assistance , Regards Phil
