Briggs have a couple of recommendations for motor mounts in their site that reduce engine stresses and vibrations(this one is not included),. Bbut with the solid base plate from Burris it should be reasonably strong and it offers the advantage of chain adjustments from above.
However at US $170 for the complete kit it is pricey. Probably less if you already have the Burris base plate. It is available from http://www.innovativekarting.com

Here is a link to the motor mount I use and what we purchased for the Try-A-Kart fleet $40.95 US : http://www.bmikarts.com/Motor-Mounts_c_243.html
It has the solid base plate. All the hardware comes with the mount and it is in imperial sizing which is bit of a pain but the motor mount clamps can be tightened with a 6mm hex with no problem. These ones are not anodized but the machining is well done and the aluminum is good quality.

They also sell the fancier more expensive mounts that are still under $90.

I have a 1 or 2 of these mounts I can sell.
