The Wizard of Naz has granted me new powers in the form of the re-engineered Runaway Rally Ped. What do you think?
Current Setup highlights:

We are working out some little details like what air filter I want to run, but the bike starts and idles beautifully, and pulls like a truck up to what feels like a solid 50mph- I will provide some GPS data on that as soon as we are through tuning. The old setup ( https://www.mopedarmy.com/forums/read.php?7,2111611,2925053#msg-2925053 ) achieved over 50 mph numerous times in my quest to blow it up, so I expect this build to equal or better that without most of the issues I encountered with either the shady Wizard Kit piston, tiny stock carb, or iffy performing notched variator used to get there before.
This has been a really fun project and was only possible at all with some serious engineering on the part of Naz.
