Si Davide, l'ho aperto perchè* c'era uno strano rumore....non l'avessi mai fatto. Albero sfilettato nello svitare il dado, è* tutto incollato. Gabbia a rulli sullo spinotto del pistone, è* cascato un rullo. Ho cambiato i cuscinetti, sto aspettando albero, biella etc nuovo....boh speriamo bene. La cosa positiva è* che costa molto poco e con un canister diminuiscono le vibrazioni. Con i barilotti parti col minimo alto per atterrare che quasi si spegne. Che palle!! Ne ho tre e francamente finchè* vanno lasciali andare, non aprirli se no devi sostituire il 50% dei pezzi. Vorrei provare un DLE per vedere la differenza

Io non capisco come si fa a dare 5 stelle ad un motore che ne vale perchè* costa poco allora va sempre bene tutto...vibra di brutto che ti apre in due il banco prova immaginarsi sul modello..scampanella di gabbia a rulli di biella e pistone come un martello..pressofusione pietosa con un buco che nel mio dallo scarico non arriva per poco al pistone...cdi pegasus differente dalla foto....poi ne ho ancora ma non mi va di scrivere...dovrebbe costare 100 euro spedito un coso così*...spero che queste recensioni servano per migliorare queste boiate.

Exhaust = 98 grams
Ignition = 119 grams

It is different from my mates RCGF. the carb is at 90degrees to his. needle are accessed from the side.
