magna engime noise

Thanks for the part information it is somewhat confusing they might even call it a chain tensioner in the shop manual. Good news is I made it to my destination. Now I am going to start taking my bike apart. Does anyone know why this piece would fail so early, my bike has only 15k on it?

Ok I just removed the front one, but guys how to tell if it is broken? It looks just like in the picture on the parts list. Usually I can tell if something is wrong but it is not clear to me.

You need to take it apart and you will see that the spring is broken and we have bent a new bend in it and run like that I think Charles is still running his that way LOL

That picture shows you the piece that is broken

thanks for the picture but forgive me I don't seem to have a good understanding of exactly how this thing works and or how to get it apart without breaking it if it is not already broken. I have a feeling that you guys are right this is the broken piece because when you shake it you can hear stuff moving around inside, it does not exactly sound taught. or sprung on the inside.

Shot you a PM give me a call..

took the front one apart and putting it back in the bike now, the front was 100% going to remove the exhaust and check the rear next.

I always attributed my failures to my "Bat Out Of Hell" riding style

Don't worry about the rear one. I'm not sure if it's because it's larger or what but it's not near as prone to failure as the front. If you found the broken parts on the front one then just leave the rear one be. As to why they fail, that's anyones guess. Vibration, heat, who knows. The spring itself doesn't keep the rod out on the teflon tensioner. The spring is basically there to keep the screw section from backing itself up. When it extends it "locks" but if the spring breaks it slowly screws itself in and then you lose tension. Therefore I really don't know what causes them to break. me and Charles took them apart and couldn't come up with a rational theory either. They just break, however if Honda does have one flaw over the years across their many models it is a weakness in chain tensioners.

yes but if it is not my rear cam chain tensioner, what has gone haywire in my engine????

sounds like we have something in common lol

well Jimmy and Allen and everyone else I tested my rear cam chain tensioner using the special tool, which btw can easily cut out of 20 gauge stainless sheet steel. Both chain tensioners are 100% yet my bike is making a ton of cam chain noise.... I am now going to put my bike back together maybe one of the tensioners was stuck or something. I am still confused I have plenty of oil and two good chain tensioners yet lots of cam noise.... I am getting worried I need to take the cylinder heads apart and inspect the cams and the chain visibly maybe it could have jumped the track or something, although I feel that would be highly unlikely. I am worried my magna may have bit the dust at a young age?????

It would be the first one I have heard of not saying it cannot happen but very very very very rare.
Did you pin point the noise like we talked about .

tedkraus · July 11, 2011, 03:37:05 PM

top end right side, both cylinder heads I am messing with it more right now, and will try to post a video asap might need some help with that.

Hey guys, I wonder if this is the issue that was supposedly on only the 94 magna's??

Well it is a 95 but might be the cause.
