Ha haaaaa, I just had to call the post that because I just finished up one of the most brutal classes I've taken for engineering, Electromechanical Control Systems or 'controls 2' as it is called. This was my last ME class (only physics, math and humanities electives to graduate) and I'm perrrrty happy about it, so now that I'm finally 'out of controls' I can get radical on mopeds again.
To start with I had to fix up this shoddy excuse for a website. I know I should be on here more, but my ADD pulls me toward wasting all my time on the $@#$ing moped forums all the time, starting fights with depressed elderly people and the mentally handicapped. A book I read about ADD said that people with it are drawn to internet forums and chat rooms and mopeds... just kidding about the mopeds part, but its creepy how true that can be.
Anyhow, taking a break from all that nonsense and focusing on this for awhile has it looking better. This whole debacle started with the picture on top getting resized and ended with me getting so mad that i deleted the whole template and just left it with whatever default. The new 'OOC Choppers' website... which this is, of course, comes with a cleaner interface that is easier for your eyeballs to find content on, a left side junk tab which i like better, and a welcome-to-2004 screen width of 1000 pixels. I also added RSS feeds for everyone's blog and made that shorter so now people who update more often are at the top. Your blog link is now governed by an automatic meritocracy, instead of a myspace-esque 'who do i put at the top' decision that i refused to address.
In the next couple months i'll try to add a couple 'projects' pages for my ongoing projects, and i'll try to get the moped factory blog turned into something useful. I have so many products in development and coming out that i want to make it easier for people to get good setup information and hopefuly i can spend more time producing useful content than repeating the same crummy instructions 20 times. A 'how to properly shim your head' video is needed very badly so i'll try to get that done too.
On to mopeds, I've been pretty dormant the last couple weeks but got started up again last weekend trying to re-stock some popular items. I made over 30 sets of hobbit rollers, an entire 10 foot chunk of material was cut into tiny pieces... made a couple custom heads that have been on the shelf for a couple weeks, and got some computer design work done. This week i'm trying to get prepped for next weekend, i hope to have two long days of cranking out everything from cylinder shim plates, to batavus intakes... yikes!
Personally I'm trying to get my bridgestone ready for Frozen Snot ride, march 17 this year. Caitlin wants to go so I'm going to try to get a motorcycle fixed up, as the puch polini is still a ways out and totally untested, so she'll have to wait. Frozen snot is always a fun time to bring out your winter project and this Bridgestone is coming along nicely, so i'm pretty excited. I have a ton of work to do, but its starting to come together.
The polini is hours (a lot of hours i guess) away from running, but those hours i just haven't had. The engine is 'done' it just needs to be assembled, really. All the shims and everything are in place, but i need to have 2-3 uninterrupted hours to sit down and piece it together. ZA's aren't black magic or anything, but you do have to take your time and work clean, careful and precise. Currently the garage is pretty messy and 40 degrees, not very condusive to that kind of work. I need a spotless, brightly lit environment to do a good job. Also need to finish fabricating the pipe and piece together a few sundry items such as air filter/velocity stack, intake manifold modded to clear ZA, pedal shaft extension, electrical system. I'm pretty sure at least to start with i'm going to run the 2041 pietcard box on the 'treats' cdi stator. I'm hoping for a mild retard around 8 or 9k rpms. The LK95 pipe i got from Devin at MLM really needs to be retarded when it hits, and there is no way i'm springing 200+ bucks for one of the top dollar CDI units.
Oh yeah, weedwacker? Another in my series of tuned up vintage 2 stroke power equipment. This is about the fewest moving parts you can possibly combine to make a running engine, which makes it cool. I was really missing not having a weed wacker last year with my crazy hillside 'back yard' so this year i can trim the weeds and pick up dog poop!

Ah shoot
Despite being an engineer and having quite a bit of experience with computer type things, writing code, configuring networks, hardware, software... etc. I find myself being completely unable to navigate simple systems. Facebook boggles the hell out of me, "i" phones dont make any damn sense at all, and apparently the totally idiot-proof interface of 'blogger' is beyond my technical sophistication.
Long story short, I started out trying to figure out why the heading photo got resized down to tiny, and somehow i messed up my blog. Now pictures are all whack-sized, colors and themes are lost, and a bunch of time i put into making it somewhat readable over the years is all gone. It took me a couple weeks just to figure out how the heck to get back 'in' to the control interface and make it somewhat legible.
If i get some time here in the next couple weeks i'll try to fix things and add some of the new fun things i've been working on. In the meantime sorry if it looks crazy around here.
I'm putting some time into developing a new website for moped factory, and parent company motzing engineered components, on my own server, without glitzy templates and crap... just something simple and ugly (think geocities style) with good valuable content, then i can keep this blog for updates on dumb stuff like when i changed a throttle cable and when i'm feeling sad about backstreet boys not getting back together, and whatever else dumb stuff that people put on these things... cake photos?

A quick one
Not much to say, trying to blarg at you more often than not here, but its not easy with everything else going on. Plus things in my own garage are pretty stagnant at the moment, haven't made much progress on any of my poorly running bikes.
Despite my best effort however (to avoid buying more bikes), I did acquire another $100 Pinto. I know you guys on the coasts (or anywhere that isn't milwaukee, i guess) will hate me for this, but its almost hard not to buy $100 barn-fresh Pintos here. This would probably be the 7, 8, maybe 9th Pinto that has come to me in about this same condition.

| From Blk Pinto 12_11 |
The throttle cable is ALWAYS broken, the chain is usually froze up (missing in this case), the forks are loose as hell, and the pedals are bent, but the EE-FIDDY is in great shape. No speedo, so no clue what the miles are, but the tires are original and hold air. Not too worn down either.

| From Blk Pinto 12_11 |
It also came with 2 14mm bing carbs and a box of other fail from the previous owner trying to resurrect it. I talked to him and he wants to buy it back from me if I get it running, but the more I think about it, the more hoarder-ey I feel. I've never had one of these with snowflakes before, I usually get the 'red' orange ones with spokes. I dont really like snowflakes but for some reason I really like this little bike. Either way it will have to wait a couple weeks for me to get my dollars up enough to sort it out properly.
Speaking of getting my dollars up (a phrase borrowed from The Illustrious Miles Fox) I've been cranking out new parts like a monkey on crack lately.
I turned a few heads for the Treats gang, the bulk of it Puch stuff, but also trying to bulk up supplies of vespa, motobecane, and there might be a debris laying around somewhere. The Metrakit 65 head I started doing 5 or so years ago is still a hot seller, and my processes (sandblasting, paint, finishing) have gotten a lot better thanks to my new machine shop and upgraded tooling. I daresay these are some of the nicest heads I've ever made.
I also finally put a bracket that has been riding around on the bottom of my sachs since, oh, 2007? into production. The final version is burly 12 ga steel and powdered in MopedFactory blue. It will let you put a Simonini Peugeot Circuit pipe on your lowly Sachs 505. Anybody want to test it on a 504? Freebeeez! The way the pipe is set up from the factory, the header is the exact same size as the nipple of the Athena Kit, but for stockers, you'll need a little shim. I'll be making those very soon so hang on to your hat.

Oh yeah, what else you ask? As if all those fantastic parts that i've been slaving over isn't enough to make you happy, I went ahead and did another production run of ZA-50 Billet oil fill plugs. Why? Because I needed a couple for myself and figured while I was at it, might as well make 20 or so.
 |
| From za 50 drain plug |
These new ones are, once again, better because of the improved equipment at the new shop. There is a miracle machine there called a 'speed lathe' that makes it easy for me to keep the quality control on these like 300% more consistent. The last batch I ended up throwing out about 1 in 5 due to the o-ring groove getting cut funky, but this batch came out almost perfect. They also are faster to make, but I cant drop the price people, geez they are already cheaper than the 30 year old rubber crap Puch is trying to give you... and it ain't even in stock.
oh yeah these fit in your rare as hell x-50 3 speed hand shift moped engine also, but dont bring it up, i just sold mine and it makes me a very sad panda. Oh well, on to bigger and faster things hopefully.

A shop day, back on the Pugeot
I was able to get a day in my workshop finally after several weeks. When I started making mopeds my business, I had plenty of moped time to go around and was able to keep up on a running bike or two, my projects, etc. Now that life has gotten crazier all moped time (which is much less) goes into making parts now, and a pure, unadulterated, shop day of just dicking around and sorting things out, is a rare joy.
I cant remember where I started, but first project was Le Peugeot. This was easy stuff but frustrating/time consuming BS. When I loaned it out at the rally, somehow (this was probably happening before the rally but I didn't notice) the exhaust rapidly began disintegrating into its component parts. This is that stupid pipe that started life as a 'faco' and is now mostly hand fabricated with only a section of the chamber original.
The flange that screws into the cylinder broke off, so i welded in the higher-quality stock peugeot flange and a section of pipe, along with the peugeot stock nut which was much nicer. This held for most of the summer, but finally let go sometime during the rally. My apologies to Seth for the bum-ass loaner bike. The wimpy little sheet metal bracket under the engine disintegrated even after being welded closed, and it didn't take long for the flange/header to break and let go.
So yeah, i welded that back together. The handlebars that I started replacing a couple weeks ago finally got new longer cables that aren't frayed and corroded, and now the handlebars aren't bent and hastily welded back together. Also a much more comfortable angle.
True to form, she fired up on the second kick after i dumped a carb-bowl full of varnish gas out. My bone head brother stole my good fat OEM peugeot belt and i was forced to use his rolled-over shredded to heck belt of unknown provenance. The bike was a totally new animal with the thinner belt, definitely helped even though it was slipping like crazy.
Rode to work yesterday and made it, although i still cant figure out this top end 4-stroking/misfire thing. I've tried different timing, different jetting, different plugs, and i'm still totally flummoxed. It just feels gutless, like bad timing, on the top end, then when you go down a hill or pick up speed around 37-38 mph it starts to four-stroke like crazy and slow down.
The intake is still stock and who knows what is going on with that pipe, so either of those could be causing the flow to choke abruptly. In the next couple weeks when i get paid for a few things (most notably selling my precious X-50 motor) i'll invest in one of those malossi SHA intakes and put the 16 SHA that came off my 'ella' maxi on to the Peugeot and see if we cant get her blasting properly. Also the variator still needs attending to, so that will probably happen all at once.

Two steps forward, four steps back
I'm not quite ready to go Mike Ness on the whitehouse or anything, but these lousy A35 manifolds were a bit of a set back. In addition to taking way too much effort to make and costing me a ton to set up all the jigs and such, they have been somewhat problematic in that they are the first product I've made like this. There is a good reason nobody else makes these things!
Version 1
The first batch of 10 had some quality control issues first of all, the welds left something to be desired visually (they were airtight- tig welded inside) and the powdercoating was a bit spotty. Definitely not up to Moped Factory standards. I was in too much of a rush and sent them out anyway and right away one of my product crash testers got back to me and said that there was a placement error, on the A35 frame the old intake (ver 2) went right into the front side cover bracket. The bike I tested them on was an A3 and slightly different in that area.
Version 2
So last weekend, the forward progress was interrupted to re-make the offending manifolds, with what I hope will be a more universal and all-around better design. Version 3 of the manifold is less trick, bringing the carb out farther from the frame, and on the right side this time (starboard), instead of the port side. As much as I like designs that allow you to keep things tucked in neatly, the Tomos engine and frame layout doesn't give much of an option for that. Perhaps in version 4 I'll use an actual a35 frame and make it specific to that model, in the mean time I've got something that will get the job done and should be a bit more universal for all the hackers and wierdos out there putting these things on Puchs, Batavus (more regarding this soon!), etc.
Version 3
The new models are welded with some tricky machine shop magic to give much better looking welds. Mig, not tig, which has certain advantages to the manufacturing process. Mostly that its faster and doesn't heat up the plate as much, so it wont warp as badly, and it looks so nice.
And another pic to show clearance:
This is finals week coming up here, so I'm working on a pile of final reports and crap, but next week I'll be hard at it getting some more exciting new products out and I'll mock up a puch frame to make sure this intake clears... take some pictures.
If all goes well, hopefully I can get some work done on some of my own projects, might make for more interesting blogging.

Moar parts
Had a busy weekend, finally was able to finish up a couple products I've been developing during the last few weeks.
It sounds kinda silly saying that, because most of you (especially if you had a machine shop at hand) could have made any of these things in a couple hours, but its totally different when you are producing things to sell. Testing, quality control, all kinds of things have to be done. A big part of what this experiment with the moped business is teaching me is the concept of 'design for manufacturability'. It means altering your design to make a product easier to produce, or more consistent to mass produce. Its the missing link often between a good product and a great product, or making a profit/not making a profit.
If you're going to stake your reputation on a product, you better be darn sure its going out the door correctly made, a big part of that is consistency. When you make one intake you can mock it up on your bike, tack it in place, bend it to fit, finish weld... when you make 10 intakes you have to make a jig to cut the tube, a jig to bend the tube, a jig to hold it while you weld. By the time you're done with all that you've spent weeks engineering a process. The good news is, it pays off in time by ensuring a high quality product and making them cheaper to mass produce. Oh yeah, I'm learning a lot as well, and as my mom always says 'education is expensive'.
The first part i'm excited about i've been making for awhile, just for my own use and for friends. These 'E50' stands- which fit all puch engines, of course- are really handy for rebuilds and for starting your engine on the bench. The originals had goobery welds on the outside, and weren't always 100% perfectly square. I made some changes to my design and managed to hide the welds, make them stronger and more accurate, and shoot some pretty blue powder on them.
What do you think? The blue powder was a reccommendation of my brother who is always reminding me I should work harder at getting radical. Black would have been the safe choice, but I like this blue, and now when you start seeing all my stuff coming out in blue, maybe you'll recognize moped factory products when you see them on other people's cool mopeds, or something... I'm retarded when it comes to marketing, so y'all should know that MF stuff is less than 2% hype. Boring eh? Whatever, if you want hype go buy some Coke or a pair of Nikes.
The other part that i've put a ton of time into lately... and boy have i ever... is this A35 to 16SHA intake manifold. Ever since Handybikes ran out of Daelim manifolds sometime around 2008, there has been a lot of hair-pulling by the moped community about finding a good, well fitting, 16mm SHA manifold to fit the A35. You can use that straight shot one from treats, maybe, if you have just the right carb and the gods are smiling upon you. And dont even think about changing a jet or running an air filter.
A guy emailed me asking if I could make him one and it got my juices flowing about this part again. I'm literally going to bleed money on these things, but they are so cool and so badly needed, consider it community service or something. It required about 10 modifications to my plasma-cut flange, to get just the right angle on the pass-through of the tube. A jig had to be made to ensure the bender would bend the tube at just the right angle, a jig was made to hold the tube and cut it at just the right angle, and the tube itself requires a machining step to put the clamp-mount spigot on the end just perfect.
After about 10 prototypes moving the carb into different locations, it ended up here. I mocked it up on an A3 so hopefully it works on A35 frames just the same. I cant exactly remember how those frames are different (if at all) but it should clear side covers and everything, so you can keep sleeper status even with a kit.
This week I'm cleaning up the garage and getting ready to put together my ZA-50 finally. This stupid thing has taken me forever, basically because I want it to be perfect and run forever. Is that too much to ask? The last ZA-50 I rebuilt had at least 20k on it before the bearings got so sloppy that I finally had to retire it. Hopefully this one with improvements like relined clutches, roller bearing crank, and higher quality bearings (I've replaced almost every single bearing in the whole engine) will allow it to run hard with a Polini for many years to come as a daily blaster.
