Hello guys! I am have CBZ Extreme since april 2012.I have an issue with the bike that its just 7000 km & its chain set is loose. whenever I go for a service I get it checked but again after 50-60 km is loosens up. Can anyone advice me what to do about this problem as it disturbs while driving. And gear shifting from 1st to second is also not smooth. - Nikhil Sharma
