Jan Thiel I´m asking out of pure admiration of your work. If the 125 and 250cc twostrokes had continued to this very day, and you were still working on them at Aprilia, how many horsepower do think they would have today ? |

That is nothing short of amazing, and from only 125cc. I dont doubt you that it is possible :) Thank you for taking the time to answer my question ! |

| Cela fait plusieurs fois que je vois des photos de montage admission 24/7, sans qu'il n'y ai trop d'explication sur ce que cela change au fonctionnement du moteur.
Quelqu'un a des informations sur ce que cela apporte en performance ou pas? Peut être une courbe de puissance/couple?

| too difficult for me to write this in french, so sorry.
24/7 (as in opening hours of a shop : it never closes, open 24 h for 7 days) : as long as the engin is "on the pipe", the crankcase can be open 24/7 , no reeds/disc/piston needed to close it so the piston can pump gas from the crankcase to the cylinder, because the pipe sucks that hard that it sucks through the now always open intake directly through the carb. the moment you drop below the powerband of the pipe, the crankcase needs to be shut again so the pston can perform the sucking again. |

| Avec des clapets, peut on considérer qu’ils fonctionnent à tout les régimes ou qu’ils n’ont pas le temps de se refermer et restent constamment ouverts au régime de puissance ? |

| Merci janbros pour ta réponse, j'avais compris la théorie mais en pratique cela fonctionne t'il? Y-a t'il un gain avec l'admission 24/7? Cela permet peut être le montage d'un carburateur de plus gros diamètre? Faut-il un volume de bas moteur plus important pour que l'admission 24/7 fonctionne? C'était ce genre de question que je me posé!
Oui Adco, les clapets fonctionne a tout les régimes!
