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.
I had what sounds like a similar situation with my 03 954. I took it to the local shop I've dealt with many times & trust. They replaced the clutch, clutch basket, etc. & that fixed the problem.
i hear you, actually when i got the bike it was running on 3 cylinders, all vacuum hoses were in the wrong place, radiator tabs broken etc etc and i fixed it all up. that was like 3 years ago, so this knocking sound is new.
