2005 Yamaha Vector Handlebar riser??

[speedy123]

Looking to add a 2" powermadd riser-looks like the stock cables are long enough-however there is a "notch" on the new riser?

How would I install the riser and how much should I torque the bolts?

Also should I use all of the hardware that came with the riser or use any of the factory parts i.e. nuts/washers?

Thanks for any advice!
