magna engime noise

Ok could the cam chain tensioner in the rear be working but still spring back and forth when you remove the cap screw? maybe when I screwed it in and out several times it tightened up even though it is broken inside? the cam metallic chain noise is gone, although now there is a new noise. It is a tick tick tick tick tick sound definitely coming from the right rear cylinder (#3 I think)... my phone died and I am recharging it now and will video tape this noise soon.

I am not sure how to describe this, but I believe the rear cam chain tensioner could be bad but still have some spring to it somehow, the cam noise quieted down before but is now coming back, also the ticking is coming from just above the exhaust heat shield on the rear of the rear of the rear right cylinder if you put a screwdriver stethoscope on part# 95701-10045-02 you can hear the valve ticking the loudest. I just did a video tape, but unfortunately the sound quality on my camera is poor when compared with its video quality.

EDIT: I am guessing it is a valve problem, most likely exhaust, possibly a result from my cam chain being all messed up. If you guys would like I can post the video although I think it is useless because you cannot hear the sounds I am describing.

EDIT#2 when my bike cools off again, I am going to completely remove the rear chain tensioner and take it apart instead of just springing it back and forth with the tool I made, also does any one know how to go about inspecting and or replacing/ adjusting a valve? is the valve thing something I can do myself?

Maybe the spring is sprung? Weakened?

tedkraus · July 11, 2011, 09:33:54 PM

Maybe somehow the spring is not seating right or something? I am going to remove the rear one tomorrow instead of just loosening and tightening a bunch of times using the little sheet metal tool you make. I just road the bike about 20 miles more and there is some cam noise but not like I had before I started messing with the tensioners, I guess I am more confused then anything....

Just a shot in the dark here but possibly the teflon tensioner that that the lifter (using the Honda terms here) pushes against has somehow shifted or something. Now THAT would be rare because I have truly never heard of that happening but just throwing it out there.

Btw, if the spring tensioner/lifter does not fully extend you will get cam chain noise. It needs to extend the full stroke, not just most of the way. Ask me how I know

Also, I have ridden miles with a broken tensioner (uhh...several times

)and never had any ill effects afterwrds so I really don't think there's enough room in the cases for the cam chains to jump a tooth or get out of whack. Just noisy as hell...lol

Update?? Outcome??

tedkraus · July 20, 2011, 06:19:22 AM

I gave up cause I was going out of town, took the bike to a friend who is a professional mechanic he checked a bunch of things and said, "ride it". He did not find anything, and for now my noise is gone. But what would cause the tensioners to not fully extend and then function right when taken off the bike and taken apart then put back????

EDIT: I took the rear one out before taking to the shop and the pieces were 100% also.

tedkraus · July 21, 2011, 06:38:52 PM

Any more thoughts guys, has anyone had to replace components of the timing system before??? Thanks

I have a 95 magna, its been running great but lately there has been a loud metallic chain sounding noise coming from what seems to be the right side of the engine. Noise occurs in all gears but doesn't start until the bike is warm. Once it warms up it sounds like a chain or something inside is dry metallic shhhhssh sound. I checked the oil There is plenty, i use 10w-40 Mobil one synthetic bike oil I changed it this sprring but this noise just started. Please help! I am on a road trip with thethe bike when it started and have only my portable tools and internet on my cell phone.

try pulling in the clutch? if it goes away, it's normal.

You took the cam tentioner out and turn the tentioner. There is still some spring in the tentioner. You reinstated the tentioner. The noise level changed for a short period and comes back. This proved that it is the tentioner. Take the tentioner completely apart and inspect the spring. If the spring comes out in more than one pieces than it is broken. Else it is hard to know if the spring is bad. This was how I derermined my cam tentioner was bad. Don't make the mistake that I did by taking the cylinder head out to check the valve springs to find that they are perfect. Good luck.

I have had both tensioners apart on the bench, they are 100%,

Chad in Michigan · July 31, 2011, 11:36:57 AM

how many miles on the bike? there is another chain that drives the oil pump under the right side cover. it would be the first one i've heard about that would be streched though.

tedkraus · August 07, 2011, 01:06:54 AM

15k miles.

Greg Cothern · August 07, 2011, 10:44:22 AM

I would put my money on the tensioner nonetheless. I personally would replace it. IF for some reason that doesnt cure you will have a tensioner on hand for when it does go.

Mileage is not necisarily an indicator on tensioners, they go from high RPM living.

tedkraus · October 19, 2011, 03:34:52 PM

I guess I can replace the front tensioner since the mechanical shhshss chain noise hasn't gone away but I have pulled it and there were no broken springs. The noise seems to b getting worsetoo. I got a new phone and am going to try and post a video so everyone can hear.
