So I have a sick cbr 600 ive recently finished adding parts here and there like exhaust and I had it dynod and port and polished heads and some other cool stuff done I will post pics tomorrow but I have a question, im a pretty good bike mechanic and I hear just what i though to be normal engine noise coming from right side case ( i know cam chain right...but just wait...) so I just wanted my buddy who owns a shop to listen and also have had another buddy who owns a different shop listen as well and they said the 05 cbr600 just has minor engine noise and if it was a cam chain I was hearing it would be really really loud. Bike runs crisp and very tight. What do you guys think?

I ordered an APE CCT anyways.

 

anybody.

 

 

If the CCT is gone, then it'd make a rattle which could be somewhat subtle initially but goes louder progressively. The rattle is pronounced when there's no load, so basically when you rev in neutral and then let go it'd be that buzz when rpms start dropping down. I do not see anything else making a rattle on the right side if it's from the top of the head as clutch is down low.

 

I think its just engine noise and i worry too much. Ive put 1000 miles on it the noise is still the same and it is barely there, went to every shop in town and every mechanic says "nope sounds great no cam chain noise"..

 

Just wanted to update I took apart the OEM CCT use a flat head ratchet it in and out a few times it has plenty of spring tension put it back together no noise bike runs great and run to 92 ethanol free as well
