The video is the Autisa kitted Sachs...this engine build is an Athena kitted Sachs...two different engines. I'm just beginning to build this Athena Sachs engine.

Re: Sachs by Smitty - Athena Style

What do you think of the athena kit for puchs? Do those have metal reeds as well?

Re: Sachs by Smitty - Athena Style

yeah and they break as well

...as you can see from these two pics, there is some radical ramping that needs to be done. MUST be careful not to grind through the case, and make sure to leave plenty of gasket sealing surface.

about the cost of the carb...I think it was like $178.

Zanella, they are copies of the Minarelli V1 engine,

thats where everyone gets the 86cc kits, you should go find Federico and see the drag races

Re: Sachs by Smitty - Athena Style

Smitty, what kinds of dremel bits do you use?

I imagine you use different ones for the rough cutting, the fine cutting and finally the polishing. I saw some diamond tip bits today, are they any good?

case transfer ports...

Diamond bits are really good, and I use lots of different size and shaped ones. One of these days I'll have to lay out all of the piles of bits I have and use.

I use different dremel bit kits for grinding, sanding, polishing, etc. I also use tungsten carbide bits. These are relatively expensive, and very aggressive (meaning they cut off a lot, quickly!)

I also have several rotory tools ... as I can burn one up after 1/2 dozen engines, hehe ;^)

PS I also perform lots of intricately detailed port-work in some areas with an electric engraver. Also by Dremel.

Re: Sachs by Smitty - Athena Style

They are called CICLO's .. I bet its nice down I would bring back a shit load of kits.. cylindero kit cost 20 us bucks..lol

Now to just clean up the scratches, and add my texture patterns.

Where else can you send your Moped Engine to, and watch it take transformation while you're enjoying the tropical weather in another country? hehehe!!!

Case gasket...

...I don't like the way this one laid when it cured, so I cleaned it off, and started again.

At this stage particularly, it is imperative that close attention to every detail counts. This is about the 2nd most time consuming and tedious part of the task at this stage.

Re: Case gasket...

Are your supposed to wait until the sealant is cured to join the halves? My honda bond says to join the cases after letting it sit for only a minute.

Re: Case gasket...

Smitty Smith /
smc OP

I've had much better results by letting the Yamabond cure over-night, before assembly. Several reasons I do it this way. After the gasket maker is cured, it's a very nice rubber-like (not silicone). It's plyable, but stiff. Also, if you assemble right away (or before cured), then you take a chance of it oozing into the engine, with no way of getting it back out, and therefore it's likely to mix and mingle with the internal moving parts, and likely block oil passeges. Then you're ruining the engine with sticky goo all through-out the lower and top-end, as well as the transmission (where applicable).

Naw, I'd rather do it the way I've seen professional dirt-bike engine builders do.

The only draw-back is like today, when yesterday I was pressed for time, but wanted to get the gasket on, I didn't have the chance to spread the sealant as I normally do, and when I inspected it this morning, I was disappointed in it so bad I took it all off and started all over again, LOL!!! Which worked-out just as well, because in between then I added another enhancement to the crankcase...heheheha ;^)

hot damn

100cc kits for vespa, huge port athenas for sachs... ain't for puchs and tomos anymore!!

Re: hot damn

Yea 100cc for the minarelli L1 too..

Re: hot damn

nice...looks like I'll be getting the engine back soon.

Re: hot damn

100c for manarelli L1?

Don't you mean 86cc, and V1? I've never heard of an L1.

Re: hot damn

No I don't mean the V1. Here is a picture of the L1.

Sorry for highjacking :)

Re: Case gasket...

I used loctite 515, check it out smitty. It doesn't start to harden until its cut off from air. I have used it to put together my brothers puch e-50, worked nice. "Loctite 515 is an anaerobic compound, specifically formulated for sealing flat flanges on machined surfaces. This product has high surface adhesion properties, which will assist in holding a seal in the housing or mating two surfaces together. High viscosity prevents migration of the product from the sealing surfaces during assembly and cure."
