I don't think Matt Sachs is for sure producing the head with the bathtub chamber. Last thread I read on 4cycle was that he was still testing them and playing with the design. That was just one of the high compression chambers he was trying out.
That was a while back so who knows maybe he is...
I know for sure in MI you need DOT tires if you are going to register as a motorcycle which would be over 50cc. Unless I could get it passed off as a 50cc moped :P
If anyone ever finds DOT tires for a 6" wheel make sure you post where you got them from. I could never find them. I wanted to make my TT500 street legal :(
I found this in the Motorcycle Operator Manual on the Michigan site.
At minimum, your street-legal
motorcycle should have:
• Headlight, taillight and
brakelight.
• Front and rear brakes.
• Turn signals.

LOL the Bubb Rubb is so old lol. That video has been around the internet for a few years. They had a website and someone was making a DVD or some crap of him.
I like how he almost hits the car leaving haha.

Probably not, the size difference is too large. I doubt the crank is long enough to fit the width of a 390 you would need to extend the crank O_o.
I don't have a 120 but just comparing the size of a 390 case to a 200 case the difference is quite large. Then all the machine work that will be...
It's dumbasses like that driving in traffic illegally and with no helmet especially that give karts and mini bikes a bad name. Doing stupid shit while traffic is coming.
At least the Germans with the gixxer kart had the brains to go to a closed track.
