Greetings,

I have a 2002 GXS-R600 with about 24,000km on it. I hear this strange sound and I cant figure out what it is. It only happens when you are on the throttle, and goes away when I close the throttle. Happens with load or no load on the bike.

It kind of sound like something is rattleing (bb's in a can) comming possibly from right side, cluth ? Its not a ticking sound, more like the kind of sound you hear when you left your cars hood and hear the electricals going (spark plugs).

The bike made this sound all the time last season, then stoped making the sound the start of this season, then slowly started makeing it again, and now is doing it all the time.

There is no loss in power, it rides perfect, revs fine, runs great from idle to redline but i cant figure out what this sound is. Since it does it only on the gas im pretty sure its not the chain/sprokets or anything like that, it doesnt do it off the gas so I doubt its CCT. I had the valves done at 23k and they were all in spec and the CCT was fine so I hvae no clue what could be causing it, and why sometimes it would do it and other times it would not (now more doing it than not) so is it a worn part? If so, why does it stop doing it sometimes.... very strange

If anyone can shed some light that would be great!!!!

btw I run full syntec oil, Amsoil 0W-40. Could that be it?
 
personally i woudln't run full synth.. but plenty of people do with no reported problems. don't know if that could be causing it. were the throttle bodies checked when you had the valves serviced?

Yes I had the TB's checked and synced during the 24k service, also I was running semi syntec before and it was makeing the same noise

Ive had it with this bike... I think maybe its time for a new one, was thinking the new zx6r's are pretty nice machines.

Yep, +1 on the CCT. AFAIK, it moves in increments so that explains why it stops sometimes - after it moves a notch...

Just a thought, but wax your chain, and see what happens.
Ive thought of that, and now that you mention it, I was due for a chain lube when the sound starting hapening a lot again, ive lubed it but havent had a chance to take it for a spin yet. I dont think thats the problem tho because Im sure I have heard the sound in Neutral also... but ill keep you posted!!

Thanks for the input guys.

Normally BB's in can means you're detonating. Are you running premium gas? Gixxres are kinda noisy bikes, you may just be hearing the intake howl as well. To me the this sounds almost like rattling.

Yep Im using premium gas, its not exactly like bb's in a can, its really hard to explain, it almost sounds like electircal system type sounds (fuel injectors), like if you lift your cars hood and run the engine and you can hear the spark plugs fireing, its that type of sound, its so wierd man its hard to explain

god damn stupid sound!!! Its not a ticking sound, becuase if i put a screw driver handle to my year and the tip the engine I can hear everything and its not ticking or rattling type sound..

I give up
