Wondering about engine noise

[Brasco18]

I am currently running 20w-50 motorcycle oil. In think pensoil makes it. It is specifically designed for wet clutches. I'm sure that means nothing. It seems good to me. I recently did a camchain adjustment but think I will do one again. The bike seems to get noiser after it has been run at high speeds... Also, at some point I should redo the valve adjustments. I have them set too high. I didn't have enough options in my feeler gauge. If there is engine noise that sounds like sand paper on metal and it's not the cams on the shim and it's not the camchain, what else could the noise be?

Wow!My engine has a little noise, but that thing sounds like you have an extra chain just rattling around in there.I'll bet you need a good set of ear plugs just to hear yourself think while riding that.I hope its nothing too serious.

I just finished changing the oil and i cannot belive how DARK that crud is!!! That was the longest oil change i ever did! I think only 1 liter came out of the whole bike. After the oil change it is much more quieter now.Oh btw couldn't find the listening tool at kragen

[tarzan]

Hey Kor,are you sure you got all the oil out.There have been guys who pull that big bolt that holds the oil filter housing together
and then replaces the filter .Then fills with recomended amount of oil and it is over full.Then find out that there is a bolt behind the filter housing(towards the rear) that is the actual drain.Then they have to redrain and fill again.DAMHIKIJK

oh sweet i did it right. thankgod.

[Korr]

oh crap it leaked overnight. just ordered an o-ring. no riding for a week

[Brasco18]

OMG - I just listened to the youtube recording of the engine sound... that was horrible. I really hope that is amplified. Otherwise I don't know how you could ride that. Kinda makes me want to try recording my engine to see how it sounds on youtube. What did you record the engine noise with?

[dbeardslee]

Korr - are you saying it leaked around the filter housing? That big o-ring can be hard to get properly seated. Helps to use a little grease to make it stick to the housing so it doesn't come out of its channel when you are putting it in place. How much did it leak?

[Brasco18]

Here is a good question... what should the engine sound like? How much metal noise should one hear?

Hope you don't have to replace the cam chain, clymer manual says you have to split the casings. Later 'Dog

"Ya don't have to split the case to replace the cam chain."

Just take off the valve cover and there it is.
Cut the chain, take out the cams, snake the new chain in, replace the cams, line everything up again.

Cut the chain, take out the cams, snake the new chain in, replace the cams,

No, you don't need to take out the cams.
Set the crank on the TDC, break the chain, use it to snake in new chain, and replace the link. Worked well on daily ride....

[prometheus578]

"Don't ever correct me in public again!"

No, you're quite right, Ray.
Cams don't need to come out.
We, you and I, are supreme beings.
We can do it like that.

Anyway... what some people will do... is they will tire of trying to thread in the new cam chain... grow weary of trying to snake and jump it one tooth at a time around the crank shaft.
"Gee, why don't I just put a wrench on the crankshaft and crank the new chain into place", they think.
Not only do they think this... they do this.
Now, this is all fine and dandy, 'cept... without a cam chain in place to turn the cams... and keep the valves in time, they end up sending a piston up into an open valve and then they start singing!
Must always be mindful of those without a lot of mechanical experience, Ray.
Quit being such a snob!
HAAHAHAHAHHAhaa

Prometheus ,
As I am looking for a job once again, I think I NEED to be a snob!!
Most of the people on this board trying to do the mechanical work have figured out you DO NOT turn the crank with the chain off. If one was to loosen all the caps on the cams, to take the pressure off the valves, you could turn the crank, if needed.
But, as you said, that is for the likes of you and I, who have put in the years of sweat and blood learning the way of the wrench.......

That sound is back and it's pretty loud now and it's only been about 1k miles since i last adjusted it. I adjusted it last night and saw that the "C" was all the way over to the right like it was the first time i adjusted it. I remember that it made the same sound and it would also sound like it's spinning loose if i revved it really fast when i am waiting for it to warm up suring first week of ownership. After the first adjustment no more spinning loose if i quickly rev it sound. It still makes a constant metallic scrapping sound. When i am going city speeds i don't hear it. But freeway speeds is when i start to notice it. It gets a little more noticeable as i pick up speed. It feels like someone is behind me teling me how to drive hahahahaah! that's how annoying it is I followed the instructions/help from members here, but i am still not 100% sure i did it correctly.

Remove cover, rotate clockwise until "C" lines up with that "line" marking, loosen lock nut, loosen lock bolt(how far out am i supposed to loosen it?), tightened lock bolt, tightened lock nut, put cover back on. voila!

Does something spring out if i unscrew the lock bolt completely?
I can't get it out of my head that it's the cam chain making that noise and i need to replace it. Thanks for the tips on cam chain replacement. It really helped me figure out how to do it guys
Going to check the local shops Friday to see if they have riveting tools and a cam chain.
