I know I've been kind've quiet around here lately because I've been in Lammy-Land. I rebuilt the motor, including putting a Quattrini TV-210 top end on it.
I also installed a 5 plate clutch and, naturally, ordered the wrong exhaust. I now know that the Quattrini needs a non-standard exhaust fitting/flange. I was able to borrow something that sort've worked from one of my clubmates, though, so I can keep the work rolling.
I ordered an appropriate exhaust, the Gori M-210-TV (https://www.sip-scootershop.com/en/product/racing-exhaust-gori-m210-tv_22088000), pretending that I understand neither the Sunk Cost Fallacy nor what "money" is, plus two day shipping since I'm still imagining I can be riding by Saturday.
This was the first start attempt, and ignition timing is waaaay off. It's a variable Vape, and I'd guess it's less than 10 degrees BTDC, so any time it retarded from the idle time, it immediately misfired.
I started with a PWK 34 carb, but it's too large, so I've already swapped for a PWK-28 that was on my shelf (and is Quattrini's recommended size).
And for added comedic effect, I had probably 10% mix in my test tank, so nice n' smoky.
