Smallest motor capable of combo's?

Sure would love some video of 850 and smaller. This is just a project could be for sale once completed.

KDX with a XS ss865 (1st bore 827) pump gas, 46mm carbs, b-pipe, enhancer, 145 skat mag pump.
Sort of a combo I guess. This was my first backflip I was able to ride out of on the little 827cc. Very reliable set up.
