Simson SR50 3rd Gen Electric Starter Issues: Slipping, Flywheel Mode & Broken Gear Fixes

Hello everyone, I bought an electric starter for Simson SR50 this summer. I thought it would be a nice bajer, the package came, I started editing. After mounting the starter had a problem after pressing the start button, when the starter began to spin the machine slipped into flywheel mode, the machine was knocked out because the latches supporting the mode in the closed position with the flywheel mode did not work properly. I tried to correct it, but after a few attempts, the starter began to strange loudly. I undressed it and it turned out that the mode in the primary gear broke as in the pictures, so I bought the next starter and after putting on and several attempts it became the same as with the first. And now the question is, do you have any ideas on how to fix it? I was already looking for another starter, it is very similar in the Minarelli AM6 engines, unfortunately it has 14 teeth and mine is 16. Maybe someone had a similar problem? Maybe you have an idea of what to fit the machine itself, has 16 teeth in the flywheel and 37 teeth in the primary gear, axle diameter 8 mm on both sides, overall length 68 mm, diameter of the attack wheel 31 mm, and in the initial gear 29 mm .

This starter from the current sale is in a word trash. There is also the problem that the first pieces when they appeared last year consisted of original parts, and then fakes (read the new MZA production with the original markings). As far as I know, the covers close to the starter burst - poor casting quality. The starter is probably you have a Chinese counterfeit, because the original FIEM is very expensive. You won't get Bendix, the more that it meshes in the opposite direction than usual. Look for the starter from the Chinese scooter "Kos, Mikron" (with a chain gear), it is very similar, however, it has no milling on the head with the cranksets. So when you see it in the store, compare the dimensions to that of Simson.

I found a micron starter, the blackbird on the auction site description was such a mounting diameter of 46 mm, it would give a lathe and fit the hole spacing 72 mm but it could be changed, unfortunately it has 14 teeth, the direction of rotation is consistent. From what I found in the depths of the Internet, the original starters of the Italian company FIEM were used for paragliding, go karts, so I started to look and unfortunately the price is really deterrent 800 PLN PLN fear to be afraid, and even on paraglider forums they wrote that starters often fall so I think the game is not worth the candle. If someone has similar problems, let them write in the subject, the more information the better, I found starters in goggles under the name "simonii" or "mini 2 evo" in stores with paraglider parts.

Well, it remains to apply for a guarantee and return to MZA. The new "original" MZA starter costs almost PLN 200.
In Italy, two major companies produce starters. Efel which was used in the second generation (similar used in Cagivach). Fiem from the third generation in many other Italian motorcycles, also in card engines (the direction of rotation probably agrees) and as you mentioned in paragliders.

After a long reflection, I decided that I would risk and buy the original FIEM starter. The price was high, over PLN 1000, but I ordered a slightly stronger 0.4 kW, the one I had was 0.2 KW and was correspondingly cheaper, but as you know, never too much power. I put photographs for those interested.

Thick.
Is this some fetish with that button smoking? For me, the classic charm lies also in oldschool firing with kopnik. In addition, a well-adjusted simson fires easily:

I do not know whether fetish but I did not buy anything for my birthday, I could go crazy, but the price was in euros if our earnings were also probably it would not be so expensive.

Only with this add-on do you really break youngtimer and introduce a new potential source of future defects. But your decision - if you get it, at least do it right

We will see, I hope that now it will work properly, if not always you can throw it away and return to the state from before assembly. As a simson I have in the original and the richest versions had a starter, so I do not know why you think that the extra spoils something, I have the impression that I am trying to enrich it with some little thing.

This starter is designed for PPG engines. Have you checked if it will fit Simson at all? First, the housing has to be milled where the gear box is located. Secondly, will it fit into the engine mount. In the old type of cradle, the first generation starter almost touched the cradle tube (torque arm). In the new type of bed (with the attachment of the exhaust from below) the pipe is bent differently and there is room for the starter. Currently, beds are manufactured to the new type, but with the exhaust mounting cut off, which is a big mistake in my opinion because the muffler physically attached to the engine with which it vibrates together eliminates many problems with the exhaust system.
The larger and heavier starter motor means a greater risk of breaking the cover, which people have already described as made of poor casting and cracking. It is better that you have a motor adapted to the second generation starter, because these have additional attachments on the crankcase at the clutch cover. The addition of an additional bracket is mandatory in this case.

I know, I am ready for this bed, I have a new type. And my brother will do the milling, I will make some bracket there. As for the poor casting, I was already wondering whether to fail this welding element to add reinforcement.

Do not go this way - if you have the original do not spoil it ...

It is not known if aluminum will start snot during welding. This is what happens with new MZA cranksets, and there is no problem with DDR cranks. The bracket should be enough.

Expand your thought, why do you think so since such an addition was found in the original Simons. I know that this is not DDR only MZA, but I have a VAPE ignition, the BING simson gasoline smokes 2 teeth of the kick, 90% I have in the original and this is just an add-on that you can't see at first glance. BANANvanDYK if you say that the bracket is enough to risk it without reinforcing in total I have 2 sets of parts for this starter as if something would break. One was to go to the second simson with a PVL ignition but unfortunately I won't spend another thousand unless it is going to be really cool it can but it will take a long time.

I dumb hobby in antiques - motorbikes, recently even the classic quad yamaha and sixty-year-old zetor 25, because of this I have a twist on the point of originality.
When I started the adventure with renewing the classics, I also did things that I regret today, but everyone has the right to go their own way.
As the classic said - you're just going where we've been before
