New rattle after removing head

Paul.1478 · April 09, 2019, 06:23:57 PM

After I put my 93 back to heather after removing the head for an oil leak I noticed a new rattle. I rode it because I thought it was something loose on the fairing or something
Today I removed the tank and it sure sounds like it is coming from the valve cover area.
I removed the valve cover and all looked good. Cam caps tight chain tight head bolts tight.
When moving stuff in an effort to stop it nothing seems to help.
Thanks.

Also only at exactly 2000 rpm.

I'm not an expert but the rhythm sounds like the cam chain.you would think that noise would leave some visible signs of rubbing.

Paul, that's an unusual noise. I have heard some strange sounds coming from loose or mal-aligned exhaust systems in the past.
I suggest that you loosen the exhaust nuts and make certain that it is mounted properly and re-tighten.
Regards, Pete.

Paul,

Take a picture of the head/cams with the valve cover removed please.

Secondly, you installed the tensioner with the locking paw down?

1 the exhaust. At first I thought it was coming from there also but no leaks.
I'll check again.

Randy
Will do so today and from that I recall it only goes in one way no? I thought the best bolts did not lineup I thought.

Thanks.

The tensioner can be installed upside down. With the locking mechanism up.

Paul.1478 · April 10, 2019, 10:03:34 AM

I am 99.5 % sure it is correct but I am going to check it. I read from the form about the notches facing down.

Paul.1478 · April 10, 2019, 04:39:47 PM

Ok. Chain adjuster with ratchets down as in photo
Also checked cam gears as I replaced them. Right.
Exhaust pipes Are tight but not removed and replaced yet

Paul.1478 · April 10, 2019, 04:41:00 PM

Valve cover is still off Randy /Robert is you need any other photos.
Also I forgot to say the hard plastic cam chain guide. I put it in backwards and it got bent.
You bent it back to what I thought was correct. Not sure if that could have something to do with it or not
Thanks as always.

Which guide got bent?

And we bent it back?

Sorry exhaust side.
I (not you sorry ) bent it back so it fit back in the slot in the head. I have no idea how it was before.

Intake one never was removed.

On the pick of camchain tensioner it looks like the shaft is retracted if the spring is inside on the pick the tenioner is damaged.
The sound is similar i had on my 1100. It has double walled headerpipes that rusted lose inside and rattled.You have a 1200 and those has single walled pipes .If you did not changed over to 1100
headers its not that.Just asked because the headerpipes you got looks like black chrome

Exhaust can leak even if it seems tight. I think that's the easiest to check and you should've started from there. Like someone said, get everything loose, maybe change the crush gaskets at the ports and retighten in the correct order. This way you are catching gremlins on three fronts.
Some really weird sounds can be heard if it is leaking between head and pipes. To the point you think your bike will fall apart in seconds...

I removed the spring before taking the tensioner out and retracted the arm.
yes they are 1200 pipes, single wall.

I am thinking the exhaust is also possible as well because it is only at exactly 2000 RMP, not above not below. I removed the valve cover because I had Randy's attention and had only about 30 min to work in it yesterday and to be honest was not sure I put it all back together right.
I am flying to Sacramento tomorrow morning so I will have only about a hour to do something today, I will remove the exhaust and put them back.
I have already replaced the gaskets and the order is correct. I found them numbered.
Thanks for the input.
