i have yamaha fazer 150 nd wanted to increase its pickup..!! Sum mechanic adviced me to go with the chain set of karizma,bt later on i found tha it has only 4 joints in the rear sprocket while my bike has six..ninja also have six joints...so can i go for it?? Pls tell both methods to increase pickup nd speed,which sprocket size should be used?? Cuz i have found a way to increase initial pickup drastically of my bike without changing anything but its not permanent..!! Thank u..!!
