Go to autozone/O'rileys/Pepboys/whoever your automotive supplier is and buy a stethescope with a metal extension rod on them.

Like $6.

Remove right side mid, remove tool case and pull back rubber cover.

Start bike and put metal extension rod on CCT.

Problem found (most likely) :cruising:

Good diagnostic tool to have so that you can find any annoying noises and isolate from the exhaust!

Choose to install manual CCT or replace with stock. Your choice.

 

What fuel you using? Should be higher octane or it will ping (pre-detonation)

 

I had to put 92 in it cause its what they had when I ran out I usually use 93.. but im doing all my maintenance now anyway so I have all summer to not worry bout..

Sounds good guys. I have been reading up on the CCT and from what everyone says, yeah thats probably the problem.
Yanahmean - I use 93 in mine, always. I made the mistake of using 87 one time...and oh boy, never use that again. Thought the bike was gonna take a S*** on me! Just changed the oil about 1500 ago. Bike has 12,000 on it. 2003 yr. I understand that older bikes are gonna make noise but just trying to do small things to take care of it.

 

Where I am at in Aus, The three main fuels available are 98, 95, and 91. I use 98 most of time but sometime 95 because not available everywhere. I used 91 once (my mower fuel) to get to work and back and it was pinging especially low revs under load.

I also had a ticking noise about a month after fitting slip on exhaust. That was fixed by retightening the engine pipe clamp

 

Well like I said mine is in the shop now.. I guess ill be putting octane boosters in my gas from now as well but they are gonna do The things I asked and then if the sound is still there ohwell ill know the motor is fine

Don't 03-06 bikes use regular octance gas? I know I read that in the owners manual some where.

 

Octane rating of 91, but it also says "if "spark knock" or "pinking" occurs at normal rev range under normal load, change brands of petrol."

I nearly always get 98, as over 15 litres the price isn't that much more for the best fuel available

 

Where do u guys live that u can get 98 octane?.. the maximum highest u can get at the pump here is 94 and that is very hard to find anymore plus $.50 more expensive per gallon

Can u send me some.. how much USD

Yeah, we dont have 98 here. We have whats called VP Racing Fuel. Pretty much straight alcohol for racing. NOT putting that in the bike! Id like to keep it running for a while longer. Im pretty sure that the motor is fine, just trying to fix some things and quiet the bike down a little (except the 2 bros)! I am def leaning towards the CCT. The bike has 12000 on it. Oil change, CCT, possible valve adjustment and should be good. Thanks for all your help and input.

 

So got my bike diagnosed it was the clutch basket that contains the springs.. the springs were jiggling around inside making an awful rattle..

Great to get a solution hope its a cheap fix

To those droning on about octane the guy using 98 is from aus... They use a different rating number than the us

Google for Ron / pon / mon those are the three main octane rating numbers

Thought it was strange when he said max was 94

Cheaper than what the technician originally thought but still pricey to me

Got ya.. makes sense . Go figure we (US) do it different ... I wish there was 94 closer to me ... I live in WV, USA

My honest opinion is to use the lowest octane gas that doesn't cause knocking! On my Ducati 91 does the trick anything more is a waste of money! I'm a motorcycle mechanic btw...the gas isn't any better quality wise the higher the octane. The only diff is the gas's opposition to detonation which is the fuels tendency to ignite at the outer edges of the piston(due to cylinder heat) after the fuel closest to spark plug ignites and before the flame from that would naturally reach that area. The knocking heard from that is the 2 flames meeting and the effect is damage to those outer edges of the piston(usually at the exhaust side of the piston which is the hottest part of the cylinder)! Anything higher than what u need to prevent that is a waste!

And as far as the cct...that's a definite possibility seeing as how the bike is 9 years old

Mines an 06.. n it was my clutch springs

Great info on the fuel ratings.
Yanahmean: if you dont mind, what was the cost on the clutch spring issue?
Also, when or even should I have the clutch plates and guts be looked at or switched out.

Question about the clutch/shifting... I have been told that your clutch/plates are in good condition if you can shift without using the clutch. I can do this. Is it good or bad? Or does it even mean anything?

 

Replace when they slip or no longer work .. clutch basket is gonna run me right around $200

Install and everything else idk yet.. you have to drain the oil to get it off so that's a factor too

Another noise u could here is the shaft that runs between the oil pump and water pump it has a T at the water pump end and it can get worn and chatter a little no biggy there tho
