Unbelievable!

My buddy has a 2007 busa with 3000 km on it and he noticed a weird rattling sound just after he got it back from the 1500km inspection from the dealer. Bike made this weird rattling when it was cold and everytime you reved the engine wheather going up or going down on the RPMs around 2000-2500 you heard this rattle. I thought maybe they hadn't tightened soemthing properly after the inspection so I propped the tank and looked for the problem. Man the noise sounded like the cam was loose. So we took it to the dealer since it's under waranty and low and behold it's the cam chain tensioner!

Now here's the best part. My buddy is a dealer, buys and sells cars and bikes at auctions and he always has a busa as his personal ride. He had a 2000 back in 2000-2001 and he blew the motor when the tensioner failed. Cost suzuki 5000$ to have the dealer rebuild the motor and the bike was under waranty and it took 3 months due to parts being back order.

In 2002 he picked up a 99 copper and called the dealer and they checked the S/N and said the tensioner recall was done. He kept hearing ticking after his valve adjustment, took it back to the dealer and turned out they had swapped the tensioner with the same defective model tensioner the first time. So they changed it again for the second gen tensioner. He's gone through an 04 and an 05 since then and now his 07, another tensioner!!! Incredible! And he's not even hard on the bikes, just cruises around with them with his g/f on the back with the occasional short bust acceleration. I can't believe it!

That is crazy, however when i re-built my motor on my 02, i ordered a new CCT, I was looking @APE, BROCK, all i was told to get and then guys were telling me to get the stock OEM and i was like ? lol, OK!, they told me they are improved, I did go with the BROCK CCT. I spent to much time and $ so I didnt want to risk my new 200 HP YOSH motor 12:1 c/r and have it blow due to a CCT.:wacko:

But that's the thing, there was a recall on them and they fixed the issue in the middle of 2000. I can't believe his 07 has this problem. and at such low mileage too!

Sounds like your buddy has a gremlin after him...:oh yeah:

I will never use anything other than stock CCT on my bikes...

I own a 2007 with 1400 miles on it ,and I get a tin can type rattle when I rev it to about 2500 in neutral after a 50-60 mile trip on the express way cruisin about 4000 rpm .When I start it the next morning I don't hear it until after the ride ,Haven't really investigated it yet.

Looks to be the same exact issue. Get it checked out asap. IT aint worth risking cuz then you blow the engine and you're stuck for months waiting for them to rebuild it... Cam chain tensioner change is a 30 min job.

dealer swapped the CCT, problem solved. That coulda been REAL ugly! Busabob, get yours done ASAP. You don't wanna blow the motor...

What is happening is that after you warm the engine up, the oil's viscosity is changing. Get that crap dino oil out of there. Change over to synthetic. Go with Mobil One Gold Cap. Simple enough.

[Mimic]

I disagree, it shouldn't make that noise even prior to the viscosity change. My buddy was running motul 10W40 and it was making the noise. Changed the CCT with the same oil in the motor and no more noise. I've run that oil for 6 years and never had a problem. Yes the noise was going away after the bike warmed up and the oil became more liquid but that wasn't the cause of the problem since the same oil doesn't affect the new CCT.

Get the CCT changed, changing oil won't "fix" the problem, just possibly conceal the noise.

Ornery little chap, aren't cha! I agree with you disagreeing with me! :oh yeah:

Damn CCT's. I had a shope make their take on me thinking my bottom end noise was the CCT. Sure they were trying to track it down , but they were incompetent. I brought the engine home and torn it down and found a loose end cap on number 3 that had spun a bearing. :head meets wall:

I have the same noise on my 2006 Busa. Now out of warranty, as usual. But the noise was there from 600 miles, and reported to dealer. They, as usual, couldn't hear it, but I admit it was very slight at the time. Now it's at 6500miles, so it's done well, but I was out last weekend and it's concerning me now. It's got way too loud for me, so needs sorting. Since I reported it whilst still in warranty, would Suzuki entertain replacing it for me? Or should I just go for the manual adjuster?
As a footnote, after my last ride I jumped straight onto the wife's ZZR600, (1993, 35000 miles) which sounded soooo sweet, not a rattle to be heard. Will Suzuki ever produce a good CCT?
