Piaggio sfera 50 boging at take off
Hy, im fixing my Piaggio sfera 50 2 stroke scooter that i bought. (Sfera has the same engine and frame as Piaggio Zip, only that Sfera has air cooled engine).
I putted in 3 x 8g rollers, so 4g. There were some holes drilled in exhaust so i welded them and I also removed the blind pipe (restriction). And i also cleaned exhaust by pouring gasoline in it and burning it out. There is 17mm BGM carb with manual choke and mallosi MHR air filter on scoot. I dont remember what jet is in, but i think its 55. Scooter was first bogging alot, than i insterted a piece of water hose in filter. Now i got to this state. I tried to put some tape over filter but it was even slightly worser. Now it bogs to 10 - 15km/h but after that speed it goes like crazy. What is the problem? And also after i fix that, is it worth to put 2000RPM springs in the clutch? Thank you |
