I have both carbs and I've noticed no particular difference. To be fair when I got the 104, it was gunked up beyond belief and to this day I'm not sure if I got all the junk out but I've never really noticed any difference.Like g.b. says, it's all in the porting.Good luck--jake

This is true on both accounts.They are available on German eBay but it's very difficult. I ordered a hand shifter for mine and it took forever.Some of the parts are exclusive to the manual engine but most of the clutch parts are the same, save the spring instead of the centrifical weight and the different arm that pushes the plates together when engaged.It's really fun to have a manual

Tuning for a Sachs is difficult and hard to do. Most people just take the easy way out and buy a Puch or Tomos because of the availability of parts and low prices.Sachs are strange engine types in that they have a combined cylinder and head. Although this makes for wonderful compression, it also leads to a kind of cap on top end. It's also bad because once you ruin one part, you ruin both.

About a week ago, I installed the Gianelli Exhaust for the Sachs engine. Purchased at 50cc.nl, the muffler cost a reasonable $90 after dollar to euro conversion and shipping from europe.Us with Sachs engine mopeds have had a problem finding performace exhaust for our bikes. Sure, we can slap on a Bi-Turbo for a Tomos and hope for the best. That's what I did last summer. The funny thing ab

There are two rubber bushings that go along the crank itself. Other than that, nope. 'Fraid not.--jake

I'm not 100% sure on this but I'm pretty sure all Primas have the three wire setup.Ugh. I dislike the 3 wire so much.--jake

Regardless of bcs tractor engines, general 2-stroke engines, or any other engines you may have heard about, the sachs engine doesn't require a halfcase gasket.To get my engine apart, I usually hold one side down by standing lightly on the pedal arms and then wrap a cloth around the claw side of a claw hammer. I then find a safe place to latch onto the top half of the case(usually near the cr

I'm really sorry for confusing you. Care to clarify and explain for the kid what I am talking about?Why does his bike stop each time he pulls the brakes?--jake

Sachs don't have crankcase half gaskets or exhaust gaskets.The engine is split horizontally above the transmission fluid fill line and doesn't require a crankcase half gasket unlike a tomos or puch. This allows me to take my engine apart each year to re-grease my bearings and check on the condition of my gears without worrying about having to order a gasket set.As for the exhaust, it is

Timing is a very difficult thing to explain. I'd suggest looking at "Fred's Guide to Fixing Your Moped" under resources>articles.There are many technical ways to check for spark but I guess the easiest is to check the color of the spark itself. If it's any other color besides blue (i.e. yellow), your timing might be off.Start with gas/spark, though. You can still fir

From what you are describing, it sounds like you have the crazy 3 wire set up. I hate this set up and just recently had to re-route everything because of it. The way it works is this: your ignition coil generates electricity, that is a given.Now although this might not be exactly like it is and someone might swipe down and poo-poo the notion, the way I think of it is somewhat like a battery. T

You guessed it. Because the head and cylinder are connected and also, the length of the bolts to which the cylinder connect to is very short, leaving very little room for error on that.I'm not saying that if the bolts aren't tightened, you won't lose compression, you will. You should know the difference in sound, though, it's pretty obvious. Still, I've stripped out a s

Here is how I tell what the problem is 90% of the time:1.) Put in a new or dry spark plug.2.) Try to start it. Kick it over at least a few times.3.) Take out spark plug.At this point, you can have a better idea what's wrong.Is the tip of the spark plug wet with gas?If no, you have a fuel flow problem. You can try spraying some starter fluid in the spark plug hole, replacing spark plug and t

Well, isn't there a gap in the sheathing that would cause some slack?--jake

I am a staunch opponent of the decompression valve. It's only purpose is to make the bike easier to start. Other than that, all it does it break occasionally.What I do is either rig it so that it will never open or just replace it with a bolt as I recently did on one that stripped out that hole.You'll need a new cable as your old one won't work. For that, I just use a brake cable

A word to the wise, though.Motobecanes have their little issues and differences than other mopeds. For example, the fly wheel is not held on like any other moped. In fact, the external nut that holds it on is REVERSE THREADED.Also, the metric on a motobecane can be a little iffy and might not match up exactly.Little things like that make it a difficult bike to work on but I'm not going to d

Is the problem that it's sticking or being hard to compress?--jake
Jake Van Order — 18 years ago
yes,The black wire acts as a ground but has a secondary purpose of running the current meant for ignition to the tail light.Just ground the black and you should be okay.--jake
Jake Van Order — 18 years ago
Forgive me if I'm wrong about this, it's been 6 months since I've even thought about a sachs wiring setup.I believe that black is the ground, blue goes to the high tension coil and yellow is for lights. Much like the minarelli, you hook up the black to be grounded but it also has another purpose in that it goes through the brake light with a resistor. I never bothered with that, t
Jake Van Order — 18 years ago
ground the blue, attach the black to high tension coil. yellow is for lighting. work your way up from there.--jake

I'll agree with that. I recently picked up a Balboa that was smoking like a chimney. I switched it out for Gianelli and the smoke is gone. I figured it was that because I use Motul 600 which is pretty smokeless.Try cleaning your exhaust. I like to use MAP gas, burn it out and then tap out the carbon. On most Sachs exhaust, you can take off the rear cone and tap out the baffle.Good luck--

which carb do you have and what's your jet size? also, what engine do you have? Your engine should be labeled 505/1X. X being the letter A, B, C, or D. If there is no letter, by default, it's an A engine.I'm leaning towards your jet being too small. It happened to me during bbq x. I couldn't figure it out no matter what. What's even stranger is that it happened lite

your horn is broken. for whatever reason, puch wanted to have the ignition circuit to be dependent on a horn. If that connection isn't solid in the horn, the bike will not run. this is why when you just connect the black/blue and brown wire, the bike will run.get a different horn from somewhere and you should be fine.--jake

the carabella engine is a rare minarelli engine. It is basically the same engine with carabella stamped on the fan cowling and on the intake manifold.that should help.--jake
Jake Van Order — 18 years ago
hm..does it have get up and go when you play with the choke (pulling it in and letting out rhymically)?Or is it pretty consistent no matter what you do with the choke?Also, what carb do you have? 85/12/101 or 85/12/104?--jake

The carb you are looking for is a Del Lorto SHA carburetor, common to many brands of mopeds. When buying one, check the numbers on the side usually they will be like 14/12. This means that the manifold side is 14mm while the air intake side is 12mm. The bigger you go, the better but I've heard of problems with the 16/16 not fitting snuggly onto a manifold.I also know that "1977 mopeds

if your condensor is bad, it will work. I think.the way to tell if your condensor is bad is if the engine is running and you can see spark jumping the points. Also, if your bike runs for 5/10 minutes, dies, you let it cool down and then dies again.word.--jake

Totally right on the working on the moped part. Working on and learning about the moped will help you out when you are stranded on the road without a mechanic to hold your hand.Wait a minute. I am a moped mechanic... Take it to your nearest moped shop and be sure to tip your mechanic for a job well done.Seriously. Try this: take off your side covers. You see three wires coming out of your eng

that's a good call, actually. Basically, if you aren't enough gas, trace the line to see where the blockage is. Start from the jet to the float bowl needle to the banjo (the part that connects the fuel line to the carburetor) to the petcock.You'll find it eventually.--jake

Last summer I stripped out my sparkplug threads on a rare Sachs cylinder. Mind you, the Sachs cylinder is both head and cylinder in one piece so it wasn't just a simple matter of replacing the head. After getting some advice, I decided that the helicoil was the way to go. I went to pepboys and bought the kit specifically for spark plugs. Not being too knowledgable, I did a poor job of tapp
