Give me a few days to make up a diagram or get a printer cable to copy/scan the one I already have.
ebay is where you will find most all you need, but it may take some time to get a collection because rz`s production stopped in the 80`s. zeelectronics also has some newer rz electronics for upgrades, and on here every now and then somebody is selling, which is where I got most of mine. Do you even have cylinders yet? The PV cylinders are universal with banshee cases, pistons, ect. But rz gaskets and head are required. You reeds, carbs intakes ect will bolt right up. Also to note, you will need the flanges or fabricate some for the exaust. The rz cylinders utilize a bolt on flange, the banshee is a slip on. So you will need to make a flanged adaptor either from cut of rz pipes or made. Since the PV on the left cylinder sticks out, your limited to pipes you can use. Most popular are the paul turner midrange pipes. Rockets are another common one, but also harder to find. You can always have some made to spec that will fit, or alter the stock ones if you get them to fire straight back by putting the cylinders on backwards having the carbs in front.
