i got my mechanic to
get rid of the whole "euro 3" stuff all over the bike
take aibox away to install a used Hornet 600 rear shock adsorber
put a cone air filter directly on carburetor
brought the bike to a muffler welder and took catalyzer off exhaust very easily
it's a COMPLETELY DIFFERENT SOUND AND RIDE
next steps (hopefully soon):
bigger carburetor
different exhaust terminal
sportier CDI box
almost forgot.........got front forks stiffer, changed original offroad Dunlops with TW 203 and 204 Bridgestones and got a small rise under side stand (rear of the bike had got taller but couple riding on roadholes it's not a nightmare anymore)
I like this small cheap chinese bike more and more everyday.............
