manual cam tensioner

i know the superduke comes with a hydrological cam tension er, but my engine has a chain slapping sound when under load but only at low revs so im guessing it does that because the oil pressure to the tensioner is too low.

so i was wondering is there a manual cam tensioner that is sold or maybe some other upgraded one? does anyone have a link???

May be still born. Checked DTs web site and they do not list one for LC8 application.
