Finally I've got 50s on flat.
Kitaco heavier final gear helped it out ! The mods list are :
Kitaco imap
Andrion im8
KN ignition coil
Polini variator
Shaved drive face
5,5 gr Dr. Pulley slider
787x17x30 Bando belt
GY6 50 driven pulley
1200 rpm contra spring
Dr pulley clutch
GY6 50 racing bell clutch
Kitaco final gear
And now I am still trying to find the best setup after kitaco gear has replaced with Honda Metropolitan gears. So far Kitaco is better than Met gears, too heavy for 50cc ???
