Used the head gasket to outline.
First couple of passes with a high speed cutting bit on my Dremel.
A little further out, and deeper. An attempt at keeping an even surface.
And the final product after Naz smoothed and polished the surface for me.
I'm missing a pic between three and four to show what it looked like after I got done with a stone grinding bit. The results look decent for doing it free hand with a Dremel.
Hells Satans are going to Sundance with this ridiculous, and barely accurate short film about moped culture in Richmond, VA. Check out the trailer here. Directed by the producer from MTV's True Life series. Haha. I feel partially responsible for this. This guy initially contacted me about doing an episode of Real Life on Mosquito Fleet. We passed on it, and I got him in contact with a few other Moped Army branches. That short film is the result. It doesn't surprise me since Real Life is nothing, but retarded drama anyway. Hope the Satans have fun at the film festival.
I've always preferred this version of Hells Satans.
A rad crew, for sure. I'm hoping to get back to their rally in 2012.

Two weeks ago, leading a Moped Monday ride, we shot down a big hill toward the end of the ride. Somehow I didn't feel the bike seize, but at the next stoplight, the Ciao sputtered out. I thought I was just out of gas. I flipped to reserve, and started the bike again. Only to die a couple of blocks later. I ended up pushing it to the bar we were meeting at.
As you can see the needle bearing failed. Taking the cylinder and piston with it, and leaving bits of metal throughout my case. That's two kits ruined in two weeks (don't ask about the metrakit).
Big pile of fail. Treats will be seeing a big order from me when I get paid.

As I was pulling the Puch out of the garage this morning, I realized that it had been almost a week since I had ridden a moped. Ouch. I can't remember the last time I went that long. Snow at the beginning of last week put the kibosh on Moped Monday, the following two days I drove the car to work, and during the four-day weekend, I didn't really go anywhere that didn't involve the grocery store, or going places with Steph.
The other night I discovered the varied nuances of Vespa gears. I have three different transmission main gears and all of them are the wrong size for the rest of my gears. What the hell? I had no idea. Isaac has a set of gears that he pulled from his Bravo. I'm going to try those and see if they line up properly. If not, I suppose I'll be switching over to the race gears.
The Hobbit continues to move along slowly, but surely. Digging through my crate o' Hobbit, I was able to assemble a starting clutch set up, most of the rear pulley, and a variator that is soaking in carb cleaner as we speak. Once I notch it, it should be ready to go on the bike. I need to take some time this evening before Moped Monday and cut a squish band into the head. I spent a little time last night chamfering the ports on the Athena with a file while I watched The Walking Dead. I still need to gap the piston ring, and widen the exhaust port a half millimeter on each side. By the end of the week I should have a full-operational death star engine.

First, I hand-milled the head. Of the two heads that came in the box o' Hobbit this was the better one. Unfortunately it looked like it's previous piston mate had exploded causing some pretty serious pock marks. I milled it down until I had a decent mating surface; going from 220 grit to 400, and finally 600. Not a mirror finish, but it looks better than it did before. Yeah, I'm not certain its going to work, either.
I gave the case halves a bath in some engine degreaser, and they cleaned up nicely, carefully taking off the old gasket material that had fused itself on.
Bearings pressed onto the crank.
Nice noob mistake with the press caused some nicks in the shaft. Urgh.
Case halves in the oven for 10 minutes at 350 degrees. This will not (I found out) melt the engine mounts.
Everything slipped together like butter. Bolted down, and step one is complete.
Other than the nicks in the crank, the only mistake I made was installing the large seal on the wrong side of the crank. I tapped it in and lost it as it dropped onto the bearing. Pulling it out with a micro screwdriver ruined the seal, so I'll be purchasing another one in the next wave of parts. At least next time I'll know better.

Along with that facelift, I'll be expanding to a broader range of topics. The focus will still be mopeds, but I'll delve into my other interests, too. Comics, video games, D&D, and the occasional fresh box of cereal will be discussed. I'm also cooking up a few ideas that I haven't seen in the mopediant blogosphere before. I'm a trailblazer, bitches! Well, we'll see.
Anyway. Mopeds. Yes.
I'm embarking on my first Hobbit build (that's what all the hip kids ride, right?).
One of my greatest downfalls has always been the impulse buy. I've worked on it. Really I have, but sometimes a "deal" still gets the best of me. Case in point: late summer, this year, I'm innocently working in my garage when I get a call from Vic from Portland. He's in town and is unloading moped stuff. He heard that I had some inkling of building a Hobbit, and he had a parts bike with him. $75 takes it home. I hemmed and hawed, saying I didn't need another bike in my garage. He insisted on coming over anyway. I'm strong, but when a moped shows up at my door, and I'm told to take it and Paypal later, I take it and Paypal later.
Responsible Jon later sold me his trike frame http://mopedhq.blogspot.com/2010/08/rip-hobbit-trike.html, and now I'm going to spend a rainy, possibly snowy winter building another bike.
plus maybe some of this
and a whole lot of this
should, fingers-crossed, become a street-scourge of Seattle by the spring. Hopefully it'll lap a race track or two before the end of next summer, too.
Specs are simple; 70cc DR kit, Motomatic pipe, 21mm PHBG, race crank, some sort of CDI set up, and other bits along the way. I should have the bottom end built this coming weekend. I'll snap a photo or two of the process.
It's interesting how five years ago in Seattle, no one wanted Hobbits (or Hondas in general). They've always been plentiful, but if it wasn't a Puch, Sachs, or Minarelli, no one wanted it. Oh, how times have changed. The level of tuning knowledge has grown substantially, and people are willing to wrench on anything.
brb. In a week or so.
