Although not 100% aimed at sportbikes, the above link contains over 200 articles about riding. Most of these articles are common sense, while others are things many of us never thought of before throwing our leg over our first bike, or even our 3rd bike.
I have a 05 ninja 250 that is making a knocking sound and it wont go past 10mph. Took it to pcp and they replaced the cantane tentioner but that didnt stop the problem. Now they are saying I might need a new motor. Any suggestions or feedback?
i dont know much about bikes mechanically but i know i broke a rod in a car a few years back and it lost significant power and made a knocking sound so it sounds to me like a new motor is not out of the question.
