ottimo
from davide on 24/07/2021
ottimo variatore. su scarabeo 400cc e abbinato alla molla di contrasto bianca rende molto meglio in accelerazione rispetto alla molla di serie pur mantenedo buoni consumi.
Ameliorer le cvtfr4 pour 500cm3 (492cm3)
from Anonymous on 06/07/2016
Ce variateur fonctionne très bien sur les moteurs 400 et 460 cm3 (17g/18g). Très fort démarrage, très bonne accélération, pas de vibration au démarrage et en reprise a bas régime.
Pour le 500 (492cm3 20g double allumage), vibration au démarrage et en reprise à bas régime, accélération molle, la courroie de 500 touche le carter arrière après 2000kms, l'utilisation d'un ressort de contre poussée détruit rapidement les galets. ( idem sur le 400 et 460cm3).
De notre coté, nous avons apporté 3 modifications pour le 492 cm3: courroie de 400cm3, contre poulie usinée à -0.5mm sur toute la pente, galets à cames Dr Pulley 25x17..17gr/18gr max.
Résultats: les vibrations au démarrage et reprise à bas régime ont disparue, très fort démarrage, très bonne accélération, pas de perte de Vmax VS galets 20gr cvtfr4.
PS: il faut un minimum 500 kms pour roder les galets Dr Pulley, pour qu'ils prennent parfaitement la forme de la cloche du cvtfr4.
