Hi .My beloved Hai bike sduro has started the dreaded click on the right crank. Theres nothing seemed to be loose or broken.Now is this how bigger problems begin its just i have 4months warranty left on the Yam unit.I dont want to leave it too late.The bikes done about 1400 miles.Think im right with there been 2 years on the motor.If the motor does fail whats the symptoms. Cheers.
