awesome build but how did you get the "moped" plate? Did you have to get it inspected? My Wildfire is plated but its on the "approved list"

Nope, just showed up at the BMV. Had a little bit of what's the VIN-there is no VIN-but what's the VIN-there is no VIN-let me get my supervisor but it went thru in the end.

For a motorcycle plate, it WOULD have to be inspected by the highway patrol and they'd issue a VIN. But then they'd want it to take an emissions test, and it would have to have OBD-II to pass that, and I don't know how the hell you'd get OBD-II to work with a carb and magneto. In the end it was more realistic to plate it as a moped, because that's what it is.

I found a sidewall bubble in the rear tire, so I replaced them both. Never knew you could get a bubble in a tubed tire. Turns out the rubber around the wire bead is super thin (thanks Duro) and it parted. Then the plies started to separate. No way I'm riding on that, so I upgraded to Felt Thick Bricks. Really hard to find tires in 24x3, especially if you want whitewalls.

Man, I thought I had a kickass idea: Cheap-ass Amazon kick-start lever mounted on the pedal shaft going to the rope starter. Many problems (starting with just getting the right-side pedal off). Kick-starter lever spun the pedal shaft a little, not too bad (I greased the hell out of it) but it was too easy to get tangled in the pedal. Lift the bike and move the pedal, an aggravation but not a deal breaker. Hard to get enough velocity to actually start the engine, that's a deal breaker. And the rope failed while I was trying, that's two and a half deal breakers. Oh well, it was a good way to kill time on a holiday morning.

Kick start on the pedal shaft that pulls the recoil rope? Man your herb must be better than mine lol. Nice bike man. Thanks for all the wonderful pictures and truth of what worked and what didn't. That Springer fork looked so cool but if you don't feel safe riding it you need a huge desk for a paper weight that big. I'm glad you went back to the other forks and kept at it. I imagine a four stroke with belt drive is as smooth as it gets. Besides electric of course.

Here's Springer 2.0, a Sunlite Deluxe I found on Amazon. Pricey bastard, and here's why: It's built right.

For starters, it weighs about twice as much as the ebay special. That alone inspires confidence. All the components are about twice as thick and it all has a much better quality feel to it. And:

There's plenty of room for my fat tire. No more worries about rubbing. I replaced some of the spacers with rubber hose for some rebound damping. The top bracket clamps onto the steerer with a beefy Allen screw, so it stays put. FYI, if you're buying one of these be advised that they have a gorilla torque that screw down at the factory. Also, the steerer tube is really long, with lots of thread. Even on the long Electra frame, I ended up cutting off 4 inches.

Here you can see how thick the rockers are. The brake arm mounts right to the suspended fork, so there's no more rebound action when braking.

So I got it cut to size, mounted the wheel and bars and went for a test ride. SUCCESS! The wheel doesn't wobble, it's a dream over bumps and corners with confidence. Lesson learned, you buy cheap, you get cheap.

Then I added some padded leather grips:

What is it about leather and motorbikes? They just go together. Sorry it's so dark in my cave.

Still deciding whether or not to mount a fender, and how.
