    Engine casings

    keuk antwortete auf keuk's Thema in CAD Daten

    Well at the beginning I intended to built a identical model with all casting constrains and when I saw the complexity to transpose a real model on 3D with accuraty I was beginning to wonder , dammed how did they do to have such a good result so close from the original with the same details that are proper to the old manufacturing process when 3d didn't exist. But it appears difficult to have the answer, even if the 3d scan as a blueprint appears interesting. Nevermind I kept going with my caliper... So the model is very close from the original base with some optimisations. But a 3d scan would have been perfect to validates the bearing positions for exemple.

    Engine casings

    keuk antwortete auf keuk's Thema in CAD Daten

    Ok, thanks. So once you have the STL file, there are softwares able to recreate basics geometries, like plan, radius, // between axis, screw hole etc.. right ?

    Engine casings

    keuk erstellte Thema in CAD Daten

    Hello, Do anyone knows how Quattrini, Falc and SIP proceded to make their engine casings ? Did they use a 3D scan of an original casing and then make changes on a 3D model or did they recreate a full new and editable 3D model ? Maybe each one add a different technic ? It would interest me a lot to understand the process. I don't know if the 3D scan technology is able to recreate plane surface, cylindric shape with axis (for the correct position of each elements of the bearings ...) that you can use after in a 3D software like solidworks to make sketches and new geometries. I found this picture of the SIP model on google, the model is so close to the geometry of an original one that I have doubts and I would like to understand.

    Damned even with a CGN (2nd position from top) and 48 iddle jet, I still have the problem. Anyone is using a leaner that 45 jet on a Keihin33 ? However, after a little google search, when checking the float level, the float should not be depressing the spring loaded float valve pin, that the mistake I did above. I should have titled a little bit the carburator until the float tab just makes contact with the valve pin.

    Ok... the float level wasn't good, I had 14mm instead of 16mm, so I have modified it. But I still have the same symptom. I'll try the CGN tomorrow. Is it normal that the float needle spring is fully compress by the weight of the float ?

    So the idle jet was a Keihin48, I tried a Unknow44 one without touching the air screw, and the engine is still able to start without the choke. It's a choke with lever at carburator. The setup (Evo adjusted/Franz/Keihin33(150/CGL)/Polini mono reeds/Stroh intake).

    Keihin33 with 48 idle jet.

    Guys, my evo starts without the choke, what should I adjust first ? Iddle screw , iddle jet, neddle ?
  10. keuk
    outch !

    Oh that was exactly what I was wondering today unmounting my evo, the shape isn't optimum but I hesitated to make it smaller to reduce the deformations. So the main idea is like this right ?:

    10h Scootentole at Magnycours 2012... teeth party ! https://www.facebook...152864961419492

    It seems that the pin is angularly moving in his housing, so the overlap sounds plausible !
  17. keuk
    Ausfälle 2011, the piston pin doesn't look brocken though...
  18. keuk
    Interesting point of view. So I should compress the shock at the maximum, and ensure that the lever is just before horizontal position (arround almost90°/column) to have a good breaking effixiency right ?
  19. keuk
  20. keuk
    Perfect, I have just cut the column, now I need to make machine a part to put inside, what thickness are you guys usually using ? 2mm? 3mm? More ? There was a thread talking about that but I'can find it...
  21. keuk
    Well I'll try the 30mm first as a dummy. The 35mm looks a bit too much.
  22. keuk
    Thank you for the answer Tim, Now, with the wheel on the ground and me on the scooter, the angle is almost 90°.
  23. keuk
    I have the S&S part (-18mm) and a own plate (-18mm) so -36mm on the RS24. Here are few tests to see what the angles would look like. Steering column 19mm shorter: Steering column 30mm shorter: Steering column 35mm shorter:
  24. keuk
    Hello, I'm about to shorten my PK XL steering column. Could anyone give me the original angle of the lever ? (wheel in the air) Right now the lever is too horizontal, so the wheel is about 1cm backwards.
  25. keuk
    Good idea, are they homemade plates ?
