Just thinking. A lot of AF Frankenstein builds have issues with the front sprocket location.You could probably get by with a little variation from the stock location but not by much considering how the chain roller system works and swing-arm moves.

Yeah that is another thing I am concerned about. Also will have to figure out the sprockets sizes I will need to run due to the differences in RPM.

The motor I made from cardboard is also a bit misleading. The width of the whole box is actually the width of the motor and the shaft, so that chain should line up correctly but the motor shaft will be located further ahead in the fram so the chain will need to be longer.
If this is to be bike to be ridden with real performance in mind, you need to take in Hondas4life3 's comments.
Thus, you may have to make up a jackshaft / motor mount plates that incorporate mountings for the set up needed for a secondary sprocket and chain combination, to bring a sprocket to the center-point of where the original counter shaft sprocket was.
It's easy enough to make a neat little jig to key onto the flat sides on the KX's frame / subframe mount, or where ever, to then bring your 'solution' to for getting that final drive center line.
To reference the "AF Frankenstein" appellation from above : so many are just completely f**cked up by concentrating on the ancillaries, and ignoring just how massive an influence on suspension and handling the CS Center line is, in relation to the swingarm pivot, swingarm angle, and rear axle.
I've been involved with numerous Uni / College Engineering projects over the years, as an adviser / mentor /teacher. And, my goodness, I see the resources they have at their hands
. It's a bit of a lessen for the very, very few that I've allowed to get into my workshop (which is nothing but a home garage), when they see what can be done, and done properly, with equipment that is so very basic compared to what they have access to. My fellow engineers and teachers, often, try very hard for me to break my rules about people nosing around in my very basic, minimalist set up. As they (well, most of them) want their students to have at least an idea /appreciation of what can be done at a 'hands on' level, and not just rely on Computation and Hi Tech equipment. Mind you, I do love being let loose in their facilities - I'm like a kid in a candy store.
