I've been gone for months, and I can't tell you how happy it makes me that this insanity is still going on.

I've been following this thread for a while, and I would just like to say that you, sir, are my favorite kind of lunatic. Keep it up, my dude.
God DAMN I love this shit.
Are they a good bike?No, they're terrible!Are they like a Puch or Sachs?Not even remotely! They're more like a Hobbit or a Ciao, but subtract a variator and add a bunch of Frenchness.Are they easy to work on and get parts for?Oh yeah. They're probably the simplest of the mopeds from a mechanical perspective; you can take the "transmission" apart in two seconds with your ba
There are a few people out there running Tillotson (or Tillotson clone) pumper carbs. I actually picked up a cleapo version not too long ago, and I'm considering giving it a shot. Probably better for track bikes, since they apparently do best at wide open throttle.
I've got an AV10 case with a chunk broken off of the casting where the reed block bolts on. You can have it if you pay shipping and send me a Solidworks model when you're done.
I think Sean is on the right track. Leaning out your idle mixture should help eliminate the low throttle rich condition and give you a little head room to add some fuel up top.That said, my setup is almost identical (slightly different carb and reeds) and that fucker just runs hot as hell. Mine isn't running particularly well at the moment (I'm redoing a bunch of stuff and it's all
I use a gas strut on my race Moby. Works great, and you can quickly tweak the variator by swapping the struts out. I have a handful of them of varying stiffness, and using quick release spherical bearings on the ends makes changing them super easy.
On mine, I did the lock wire thing rebelmoby suggested, and I just tack welded the spring mount plate to the nut. You may be able to just let it float around, but the vibrations on mine kept causing it to twist, eventually popping the springs loose.
I've had good luck drilling the holes out and helicoiling them, but I've still gone through 2 or 3 base plates. The aluminum they use is *really* shitty.
I have a modified CR80 fork on my Moby, and while it works reasonably well, it's not great. It's underdamped (potentially fixable), overspringed (also maybe fixable) and, most importantly, absurdly heavy (not really fixable). It weighs nearly as much as the rest of the bike.I've been looking for workable replacement, but the combination of small overall height and short travel means
Cast iron machines really nicely, actually. It leaves a pretty decent surface finish and it is fairly tolerant to wonky speeds and feeds. I'd probably use a 1-2-3 block between the mating surface for the case and the bed of of the mill, and then try to clamp it carefully from the exhaust ports or something. Not sure the best way to do that, really.I have successfully decked a cylinder with a
I like to run mine into one of those little 5 hour energy bottles. Keeps everything nice and neat, and it's small enough to stuff somewhere in your frame. You can leave them open too, but they tend to "burp" a little bit in my experience.
I have a set that I'm in the process of rebuilding. Pretty well made, and on mine at least the piggyback was definitely connected to the reservoir. They appear to be a reasonably accurate knockoff of an Ohlins shock. They definitely need a rebuild though: they had completely different volumes of oil out of the box, and the oil was hilariously low quality. Looks like something you would cook w
I don't see a reason why resonance wouldn't work on two stroke engines. I imagine it isn't done more often because the gains aren't THAT significant compared to exhaust tuning, and packaging gets trickier when you start playing around with longer intake runners. That is particularly an issue on rotary valve engines, since the carb usually sticks out of the side of the case. I
Also, they actually did have CNC waterjet machines in the 70's. CNC machining dates back to the early 60's, and waterjets capable of cutting metals were developed in the late 50's. NC (just "numerical control," no computer) machining dates back even farther, with punch tape operated machines appearing shortly after WWII.So yeah, they technically could have made the frames
That price seems pretty reasonable for what it is. You'd be hard pressed to get that cut for less unless you actually owned your own waterjet machine. That said, it looks about as stiff as a day old salad. It looks cool, but a parallel plate frame like that is a terrible design unless you box in the top and bottom. It would be very stiff in bending, but without something to tie the plates tog
Dear god. Every time I come back to this thread there is some new next level shit going on.Arduinos are super simple, BTW. In fact, I would be surprised if someone hasn't already written some code that would work for you.
I could make some pretty easily, if there's interest. I just need an ID, an OD and an overall length.
Hnnnnnngh, dammit that thing is sexy.
They're the mopeddest of mopeds.
I made one out of random bits of scrap tubing from work and a couple eye-bolts. Works great. I keep the wobbling to a minimum by hooking a strap to the roof rack.
Fuck man. I know nothing about you, but I do know that depression is a cruel bitch and it's not something you can just fight through with willpower alone. There's the weird tendency to expect people (most of all ourselves) to just grit our teeth and force ourselves to get better. That's like expecting a burn victim to apply their own skin grafts.Have you considered that maybe you ar
Shit, these Doritos are totally ruined...
Holy shit you guys, something incredible just happened. God just came to me in the form of a flaming bag of cool ranch Doritos! Yeah, He said He was in a pretty bad place when He came up with all that stoning harlots and sacrificing firstborn sons stuff, and He's really mellowed out over the years. He's pretty embarrassed about it now. He says He's working on channeling his feelings
I think the idea of those "pray the gay away" camps is hilarious: let's get all the sexually repressed gay christians together, have them bunk together in the woods and go swimming together and shit, and then spend all day listening to some dude talk about how wanting to touch wieners is evil. You could cut that sexual tension with a knife. Shit, if it weren't for the whole emo
