Thanks for your reply.
I live in Korea. and its condition is.. now just fully seperated. it is imported from Hongkong that px200 never sold in Korea.
Is the malossi 210 sport without porting with Si26 128main jet still fine? I worry that sticking the piston and cylinder.
Or If porting should be needed, I can find a shop to do, Then 221 with the long crank could be an option for me..
Is it too fast or moves like a racing scooter the 221 malossi with long crank on the ported engine? It is really hard find someone did it here.
