sounds like cam chain tensioner.. But NOT it - January 20, 2009, 12:22 AM

Allright i got hit by an suv in october. And the bikes been in the shop since then. After i got out of the hospital i started her up and heard some rattling/ knocking.The sound is just like if you needed to replace the cam chain tensioner BUT it doesnt quite down after running for a while.. So i replaced the cam chain tensioner. Started her up and still heard the noise.. Thinking i maybe did it wrong i took it to the shop started it up.. they all said cam chain tensioner.. So i told them i replaced it.. They checked it out.. said it was good.. and we couldnt figure it out...Any ideas out there?
Its a 2004 gsxr 600.. a little over 7000 miles.. like i said the noise came after my accident.. however their is no visual damage to the engine.. I also had them check the valves and its not them.. they are good. The bikes holding oil perfectly also...Im at a breaking point here.. cant figure it out. Any ideas would be appreciated.

Does it go away if you pull the clutch in?

If it goes away when you pull the clutch in it's your clutch assembly and could 1 of several parts that are either damaged or out of spec.

If it remains with clutch in or out it's a possible internal bearing (crank ect.) or maybe even a wrist pin got knocked lose.

Why is the shop not diagnosing the noise for you?
everybody that has chimed in is giving good sugestions, but in the end, you need somebody that knows what they are doing to check it out for you. If a shop says the noise is your cam chain tensioner, and they replace it and the noise is still there, you are not obligated to pay for the tensioner. Most shops will only say "the cam chain tensioner is making noise, there could be more problems, but we have to fix that first"
There are many things it could be, if you are not comfortable diagnosing the noise, have a pro do it.

good luck with that. try gettin your keys back without giving up any money.

Champion Motorsports, Herndon, VA. - couldn't start my bike. Called me and said they can't do the electrical diagnosis - cost me $120. I pushed my bike over 1 mile to find out a wire was cut...connected it...bike started right up.

Baileys Crossroad Cycles, Falls Church, VA. - flushed entire fuel system and components, relined my gas tank - problem wasn't fixed after 2 months. Cost me $750 to get my bike back. I took out the fuel pump to find HUGE chunks of sediment in that lil fuel filter bag...apparently they never took compressed air to it to break that up....I don't own one

It's been my experience that if you don't have a good idea of what is wrong with your bike when you bring it in...the shop will do what any normal person would do...start from square one and find out what the problem ISN'T to find out what the problem IS....then charge you the man hours.

Where did the suv hit you? The rear, front, left side ect. The reason I ask is that if you were rear ended or the the exhaust took a hit then its possible that you developed an exhaust leak where the headers match up to the cylinder head. A small exhaust leak at the front of the engine can sound just like a loose valve or cam chain tensioner on its way out. Its only an idea so dont go tearing the exhaust loose. Its just that I have seen tons of guys pay for valve adjustments because of a ticking noise and all along its just an exhaust leak.

Heres a slightly better one.
Try to pin point the noise. Either go buy a cheap mechanics stethoscope or use a long handle screw driver.
Put the tip of the screw driver in different places on the motor and put the handle up against your head (in your ear)
Listen for your noise and see where its worst.

Sounds funny but it helps. That way you can see if its top end or bottom end of the motor at least and at the same time do a through visual inspection.

Start from there and let us know what you find.
