    Cam chain rattle question

    1997 R-1100R, 33,000 miles.

    At 3-4k RPM I get what sounds like a loose cam chain. Sounds like the chain is going slack and rattling against the case.

    1. Is this unique or a known bug?

    2. Are the ACCT tensioners spring loaded or do I need to adjust them. If spring loaded, can I buy an aftermarket manual type?

    Thanks!!

    Lots of good info there, thanks.

    Looks like I need to determine if I have the upgraded ACCT thingy. Come to think of it, the rattle seems to be on the left side...

    The rattle I can live with. It's the specks of aluminum in the oil from chain contact I dont like. Sure the oil filter grabs them but only after the oil pump picks them up and they have been splashed around the inside.

    tensioners

    If you live with the rattle you run the chance off destroying the guide rails the chains run in. These are plastic, strong plastic but still plastic. Take off the valve covers and inspect these rails especialy the lower left one. If this one breaks the case has to be split to replace it. This is not a fun job. Don't ask how I know. Sometimes noises are trying to tell you something.

    why not just replace it with the one they sell now? Why anguish over rebuilding it, see if the R12 one will work.
    Cancel that last thought, they havent been around long enough to see if they would be any better.

    New idea, since the parts wernt available I tried a different approach.

    I took the tensioner out, measured the spring free length and stretched it 1/4".

    Seems to be quieter now.

    new springs

    I bought new springs for .50 cents each and compared old ones before replacing them,old ones with about 50,000 miles we're about 1-2 coils shorter than new.New one will last longer than stretched ones I think.

    Agreed, new springs are in order for both sides but stretching the original spring as a quick way to see the effect.
