Posted in performance also, but figured it couldn't hurt to put it here.

My dad and I are thinking about building a couple of these bottom ends, if anyone is interested.
We take two 8/900 twin cases, either EFI or carb, whichever you would want, cut them in half and weld them into a triple. We have made all the jigs to get the spacing correct and straight. We then have the cases decked and line-bored to ensure correct dimensions. We would build a crank, and supply an ignition system. We have CDI boxes running the stock 900 twin timing curve, so you could either use that or add timing keys as desired.
If anyone is interested, we will look into how much we would need for this.
We could also provide varied pricing depending on the donor parts we receive.
The reason for using the EFI cases, is to have a larger mag end on the crank, to keep from shearing the flywheel key. Using EFI cases however would probably be a little more expensive, as we don't have as many of them lying around.
We could also provide a one-piece head that will accept speedwerx head inserts for extra cost.
