so ive been hearing this knocking noise for like 3 weeks now, its not a rattling sound more like a knocking, bike has 35k miles. some say it could be the cct but that would be more like rattling sound intead of a knocking one. the knocking sound its totally random, sometimes its one after another and other and sometimes is just one.

You're right about the cam chain. Any sort of 'knocking' is usually a big end or bearing failure with its randomness dependant upon where the bearing within the shell is positioned during the rotation. I really think you should get a good tech to check it.
