Ok-it only does it under a load.It's not loud or anything-its there though-you can hear it.Sounds sorta like a cross between a whine and a hiss.And only in 6th.I'll run it-I don't think its anything bad.I hope.Thanks guys,
Mike
Spray some chain lube on your chain and see if the noise changes
I'll try that.Don't make sense to me that only 6th would do it though.
It happens at any RPM,you can really notice it at about 35-40
MPH though under a load.
35-40 mph in SIXTH gear ???
