Hey guys. I just got the bike 3 weeks ago and it has been running amazing. Tonight I went out with my buddy on his 05 GSXR1000. I did two quick runs, about 40-160 then I slowed down to do another run and noticed a loud ticking sound. I immediately knew something was wrong so I pulled into a parking lot and shut it off.

- No leaks at all.
- Oil level is normal and oil looks good.
- Running at normal temperature.
- Drove it back home and ran perfectly normal other than tick.
- No hesitation, sputtering, loss of power... well it felt normal while babying it 2 miles back to my garage, I didn't beat on it at all.

I took this video of the bike after I pulled into the lot to see what was wrong. I'm sure this is going to be a pain in the ass to fix, and expensive too. Anyone have an idea of what exactly is wrong and about how much I'm gonna have to spend to fix it?:cryin

Thanks guys. Bike only has 6,700 miles on it. Only mod is slip on exhaust.

Not sure if they have ever been adjusted, I doubt it though. I bought the bike with about 6,000 miles on it.

I was just riding with 2 friends that have a 04 and 05 R1 that sounded like that last night. Not as prominent as yours but I could hear it while riding next to them. They didn't think there was anything wrong with it. It just didn't sound right to me though.

Anyone have any idea if it's a common problem on those years 04-06??

That would be freakin awesome if all it was is leaking headers. I highly doubt it, but I'll check them today. It sounds pretty loud to be an exhaust leak.

From the video, it sounds like your noise is coming from the top end on the right side.

I would check your cct first. They have been known to fail on a lot of bikes. I don't think it sounds like a leaking header and I highly doubt your valves would just fall out of adjustment overnight. I also doubt you dropped a valve because you'd notice some power loss.

I also noticed that the bike had a hard time spinning the engine over at first when you went to start it. Is that a common thing for your bike or did it just start? I've seen that happen when people spin bearings. Although, that usually comes with more of a knock vs a tick.

Check out this video



"UPDATE: I took the top end apart and found out that it skipped timing, broke a lifter and dropped a valave."

"Same bike same problem, stock chain tensioner adjusted at wrong time and thru the timing enought to float a valve too long. Piston hit #2 middle intake valve and the lifter broke and took out a piece of the cylinder head. just got thru with engine overhual and rebuild and APE manual tensioners will be on any machine i ride from know on."

That tick sounds more predominant then yours. I still think if you jump timing, hit or drop a valve, the bike will lose power or not run at all.

the header leak would be a bit more quiet when the rps go up, its a valve or cct problem
and dont start the bike anymore.

The problem with the valves isn't that it dropped or is out of adjustment. There is an issue with the valve stem galling in the valve guide. It can pretty much happen whenever regardless of mileage. It also sound too mechanical to be an exhaust leak. You have a definetly metalic sound coming from the right top end of the motor. First thing I would so is pull the airbox and look at the intake valve stems through the TB.

If its them, great. If not, the valve cover has to come off to check timing and the airbox has to come off anyway.

Thanks for the info.


Anyone have pics of what RedDevil is talking about? I'm gonna go pull the bike apart in a couple hours and not sure exactly what I'm looking for once I get the airbox off.

Once the air box is pulled you should have a nice view of the TB's

Open the throttle blades to reveal something me this

You will be looking for any wear on the valve stems like te one on the left. Make sure both valves are open when you look or the damage may be hiding inside the valve guide.

Obviously the last two are 4 valve pics but you get the idea.

Here's what I did so far. How do I open the secondary throttle bodies/butterflies? Do I have to take them off?

Warning: I don't know much about motors so this post might contain dumb questions.



I haven't gone back to the garage yet to take a look in the throttle bodies. Lets say that that one or some of the valve stems visible from the throttle bodies are damaged like in the pic posted above, would it be possible that that is the only issue? If so how about how much would a shop charge to fix the valves? The head will need to be removed no matter what right?

Would it be cheaper to just buy a used head off eBay for $200-300 and install that? Then I could sell the one that's on the bike now.


Would the valve galling in the valve guide cause that loud tapping sound? What exactly is the valve tapping on, the piston? Is the only way to find out all of the damage to remove the head?

Also I know there are some slight changes between 04-05 and 06. Are the heads the same?

And I know 04-06 have a different motor than 07-08, but would the 07-08 head fit on an 06 motor?

Alright guys I took a look at the valves through the throttle bodies and didn't notice anything unusual. It was hard to see in there but I didn't see any damage. How can I check if my cam chain tensioner is bad? Can I just take out the two bolts and pull it out?
Is it possible that a bad cam chain tensioner could cause the tapping sound in the video without causing any more damage to the motor?

When looking at the valves for wear you need to turn the motor over to look at all of them.. If it just "all of a sudden" starting ticking like that, then odds are its a guide/valve issue.

I wouldn't recommend buying a head off ebay. You wouldnt know what you are getting, valves, buckets, cams all have already worn to that head. If they get mixed up that will cause nothing but issues. You will have to spend hours measuring everything. It would be much cheaper and easier to just replace the valve and guide.

Mine looked perfect with a little over 20k miles. Exhaust clearances were a little tight so I shimmed the exhaust and left the intake alone.

You can push them open with your fingers as said... also, a right-side ticking noise is often the CCT, start it, let it idle and kneel by the right side, if when you slowly open the throttle the ticking gets a bit faster/more pronounced, may well be the CCT. I've had the experience of a slight rattling end up being the #4 plain bearing going out on my crank shaft, which then caused my #4 rod to come off and bust through the case. Happened so quick from a slight rattle to *pop* I didnt even have the 4 miles needed to limp to the nearest freeway exit.
