I replaced the rotor recently and poured in new oil and now the bike is making a rattling noise coming from the primary. The new oil looks like it contains bubbles but I know there is no water intrusion. I read it could be that the oil is being aerated. Could it be just that the new oil needs to get around into areas especially the clutch basket in order to settle or did I not align the chain correctly? I also noticed that the shoe from the chain tensioner is pretty worn and has groves, I ordered a new one just in case.
Thanks
I just uploaded a video file to YouTube with audio. I tried uploading audio file but no dice. Let me know what you think.
Check adjustment..If it was a Twinky I would say "Not the Primary, Check cam chain tensioner" But..Evo don't do that, so Chain is maybe touching something on slack side..Adjustment
Assuming the Compensator was Properly assembled and installed.. IDK, I run Solid!!
Thanks! Tomorrow I am planning on opening it agin and checking everything once more. I may have to measure the spacing/alignment of the chain and reposition the spacers. Its not a bad rattle but it is noticeable and it wasn't there before the last oil change. I will try to post a short video with audio later on.
And btw, the tensioner always gets a good groove ground into it, when that groove is ground down far enough(just a few hundred miles, if that) the chain runs on the rollers between links.
That will last quite a long time running that way.........
I used a new spacer. The clutch hub was torqued to spec as was the rotor. I'm starting to think the chain may be stretched because this time I tighten it more than the allowed and it still rattles. I already ordered a new shoe for the tensioner so once I replace the old one if the chain still rattles I may need to keep looking.
