strange primary noise
Hi all, after some advice as usual, lol
noticed today at idle i can hear what sounds like a plastic rattle / tapping from the primary area, it has no rhythm or pattern and doesn't appear to get worse when revving the bike although the engine drowns out the noise, also i can not hear anything unusual when riding but at idle its defiantly there
any ideas where to start?
I understand there is a plastic automatic tensioner in the primary but i have no experience or knowledge working on or with one?
thanks in advance

Check primary chain tension. Hopefully you have a factory service manual, which tells ya how to do that! Check it at several different locations around the chain, as chain tension can vary. Adjust at the tightest point as per the book.

Auto adjusters came out with the advent of the six speed transmission.

Thanks for the reply Boston Jim.
I just whipped the inspection cover off real quick ( hope the same gasket is ok? ) anyways not sure how in the world your suppose to check chain free play through there? Maybe your not. I had a quick look and nothing seems too out of place, I managed to push top of chain up and it didn't seem too tight or loose and nothing seemed broken in there so not sure what on earth this noise is.
