    Thank you!

    Hello, I need advice to choose good shock absorbers for my scooter. A rear one for my smallframe racer: I'm 1.85 tall 75kg. I have a front rs24 and a shity rear one. A front one for a 2000km trip up to Croatia with a px disc with a passenger and luguages (sorry it's the smallframe section) There are a lot of possibilities, I would like something at less than 200 euros each. Do you have advice or tips ? Thank you. Antoine

    Yes I intended to mill the S&S part to fit it... for the bolt no problem neither, I will use FHC screw. I found the information, the distance is 18mm, with 6mm thickness.

    Hello, I would like to drop a little bit more my front suspension on a PK steering column. I have a already the scooter&service part on the rs24 but that's not enough. Anyone knows the following dimension on the Stage6 part adaptor ? A would like to gain up to 20mm, but the adaptor doesn't have to be to high if I want to keep the mudguard... Here is a photoshop test: actual/modified

    I have moved down the lower part of the exhaust part to match with the piston (stroke 53 pleuel 105 etc...)... maybe the shape should look more like the blue line ?

    Hello, I have two SKF explorer 6204 bearings for my smallframe engine, a standard one and a C3 one. I'm going to use them on my racer engine. Which one should I use for the crankshaft and which one for the drive shaft ? Thanks.

    Do I really read 50hp on the curve, and 35Nm !!!? WOWW
  8. keuk
    Yes I removed it.

    Hello, I use a 9,6mm spacer under the barrel and the actual curve of the transferts in the casings looks really steep, I haven't modified the curve in the transfert ports of the Polini. Should I modify the Polini curve and mill the parts to have something more round ? Here are some pictures of the actual shape with original curve ( left view):

    Ok ! Do you know where I can buy some ? It's hard to find webstores that can send it to France.

    What is the red material that you use to make a copy of the transfert ports ? ( the one on the pictures of the first page ). I have started to make a 3D model of the Polini evo cylinder for fun, and I would like to have something more accurate for the transfert ports. Here are some previews:

    Do I cut the lower part of the piston too on this side ?
  13. keuk
    Hello, Can I cut the base of the barrel to fit with the casing intake ? Is it ok if the lower part of the piston goes a little bit further than the blue line ? (Transfert ports are not yet ajusted)

    Hello! I have a curious thing on my et3...I have the original electronic ignition, but the timing change ! The timing should remain the same but when I throttle it increases of 5/10 degrees to a new stable value...Is it normal ? ( I use a stroboscopic light connected to an external battery)

    Hello, What is the good torque to tighten the nuts of the cylinder head on this aluminium cylinder ?
  16. keuk
    Hello, I hesitate between two kind of crankshaft for my Polini Evo racer with engine casing intake. I hesitate between a plug'n play crankshaft or a full circle one that I would have to modify. At the beginning I was interested by the DRT Sprinter model, but I realise that the shape is very different of the reworked models that I have seen on the Polini Evo thread. Here is a scheme of the DRT model, it lets the full access in the casing maybe a bit late. Here is the model from the Polini Evo thread: It allows to open the access sooner than the DRT one, but I would have to reworked and then to adjust the balance of a full circle one... I'm still undecided..

    So for a daily use, is it better to have 185 or 180 with 30* blowout ( with pm40 / koso 28 / lighter flywheel...) ?
  18. keuk
    It's gonna be thick !!! Even without touching the transfert ports of the cylinder.
  19. keuk
    Original flywheel, and even reduced Sip flywheel don't pass !!! I should have known !! I wil have to machine a chamfer...... Timings without any gasket: 180/120 Timings with base 0,5mm gasket 182/123
  20. keuk
    I would like to adjust the timings to use it with a PM40, If I remember rightly I should have 185 to the exhaust.
  21. keuk
    Thanx for the advices guys !
  22. keuk
    Thanx !
  23. keuk
    The original is already 68/69% (56,7mm barrel with 43mm width)
  24. keuk
    Hello, For a daily use, and a good torque, is it better to keep the original Polini EVO exhaust shape and just add a few millimeters (to increase de blowdown to 185°) or to change the shape as the third one ? Maybe the third is better for a race use ?
  25. keuk
    Hello, What is the connecting flange diameter on a PM40 exhaust ?
