have an 06, no matter what the temp, i hear a noise around 5,000 to 7,500 rpms. it sounds like a loose bolt with a washer rattling. but very faitly, like most of you, i know what my bike sounds like, what noises are normal and when something isnt right. i routinely maintain my bike, and i checked for the 4th time for a loose bolt. nothin, called honda and he said it sounds like the timing chain or tensionor.


whats your thought

thanks

cam chain tensioner. buy a manual one- $50, my friend had this problem on his '05 at around 25,000 miles. replaced with manual CCT and no more vibration. it's easy to install.

is the chain tensioner from the factory hydraulic? the bike is under warranty still. bought it in April brand new from the dealer and then bought the extended warranty. with the price of parts today its well worth it

the tensioner from the factory is "automatic"- whether it's hydraulic or not I do not know. you bought an 05 in april brand new? how? they kept it there 3 years? i don't think the dealer would install a manual one- they'd probably just replace the automatic one. racers always use manual ones- it's better if you do a lot of high-revving. only downside is that it needs to monitored for adjustment.

i haven't done this mod...yet. though i'm thinking about doing it just for the hell of it since racers do it and it's supposedly better for your engine at high rpms....lol. from what i can gather- you listen and set it by "feel" and "sound".... i would assume that, yes, when it's rattling again you tighten it. i think when you receive your's it should come with instructions. the best thing would be if they supply a torque spec. then it would be cut and dry. like i say, i'm not the expert on this, hopefully others who have experience with manual CCT's can chime in here. a write-up would be good too. my friend paid $75 total for it to be done at the shop, so i can't ask him how he did it. but they only charge $25 to install it since it's so easy if you don't want to go the DIY route.

my first post says that the bike is an 2006, and yes i bought the bike this year in april (04/2008). they had it in the back, they got it out of the honda warehouse as the salesman told me. he said my area (cleveland, ohio) didn;t care for silver or single colors; thats what he said. i bought it with 2 miles on it, brand new, never titled. i figured even though it was a brand new bike, insurance saw it as a 2 year old bike and there fore wouldn't be so expensive. it was a welcome home present to my self. this noise is bothering me, i know the bikes under warranty, but they are booked till next WED. i made sure every bolt is tight. could it really be the cam tensionser?

i just turned about 5,500 miles. i am into the maintance and regular check over my bikes, been riding dirtbikes since i was 4. i took a stethoscope (?) and listen for the noise as my buddy keep it around 5000 to 7000 and i couldn't hear anything near the tensionior, i couldn't find the noise all together

i think it's psychosomatic bro. just chill out. sounds like it's fine. i don't see what can be wrong at 5500 miles. i didn't realize you had such low mileage.

yeah the manual CCT is soo easy and can get rid of that clanking and possibly save the engine. it is so said that the chain can slip off at super high revs.. but i duno about that much. I bought the ape along time ago and it was an easy install, just amke sure you put it in right and adjust it right,

How do you know if it needs adjustment? You start hearing the rattling again?
Well, I called APE and they said the "recommended" interval to check the chain slack was at every oil change, but that most people just listen for it.

I didn't really get instructions with mine, just a little piece of paper that said there should be 1/4"-3/8" slack.

I have an 05 600rr, currently experiencing a similar noise that started around 7000 miles between an rpm range of 7000-9000. at first i thought it might be my key ring rattling. Its more of a high pitch metal on metal vibration, like something lightweight rattling very fast, but only between 7-9k rpm though. ive kinda blew it off since then, seeing as i havent been able to find the noise, I have completely removed plastics twice for oil/air filter replacement and PCIII install, and have not been able to locate any loose parts. i havent tried reving in neutral to locate the noise but maybe its worth a shot (neighbors will likely dissaprove). im at 10,500 miles now and no problems thus far, just a little noise. Does this sound like what everyone else is describing? maybe CCT as well? ill ask around

i think that noise is normal. but then again, i haven't heard it. at 5000 miles it's hard for me to believe that ANYTHING is wrong with a honda.

I too have the same problem as all of you. I spent many a times riding down the hwy holding my keys so they are quiet. I have no clue what it could be. Im going to tighten my chain this week, so ill let you know if that fixes it. Another sound i noticed is when i push my bike or have it up on a stand, the brakes seem to rub and make a sound. The dealership put my brakes on and said this is normal... is it??

yea, mine make a very dull (barely audible) scraping sound, kinda like chalk (not fingernails) on a chalkboard, but quieter. seems normal to me, brakes work fine.

if you still want one, I have one for sale. I thought it was the chain that was making my noise for the engine and bought the APE manual CCT for it and found out that it wasnt the chain but the rods so mine's pretty much new, PM me if you still need it

I have both of these problems with my bike also. The rubbing noise with the brakes or w/e just recently started... But the metal vibration noise is pretty anoying. If it's not a problem I guess I won't worry about it... but is it normal?

the brakes rubbing is normal. as for the engine sounds you guys are all stressing out about with your 5000 mile, barely broken-in bikes, i'd have to hear these "strange sounds" you guys are talking about but my money is on you guys being hypochondriacs. I guess since I didn't have the luxury of starting out on a new ass bike with no miles (my first bike was a 1970 cb450, then 1986 zx900, then 1982 honda sabre 750)- i'm used to hearing noises and ignoring them unless there's actually something wrong with how the bike performs. bikes make more noises than cars.

if a noise is associated with a performance issue - i.e., the noise corresponds to unusually high vibration or something like that- then it should be investigated. if not, i wouldn't stress.
