It appears when you install the kit it would be wise to replace the OEM hydraulic belt tensioner . I'm a little pissed at myself for not doing it when I upgraded my VT-1 kit. It's a good part but at high mileage and with extra strain from a supercharger can and will fail. The only option which is not a good one would be to recommend a mechanical tensioner which would be a PITA as one would constantly have to check it. It is only a 75 $ part so I agree it should be replaced no matter who's kit you are going to install.
