Is my chain supposed to rub against the top of my rubber chain guard?
It has grooves in it from the friction, and when I accelerate or maintain a steady throttle while cruising I can hear the chain whirring even over my Cardo and NO BAFFLE RACE AKRA. The wheel is aligned, new chain and sprockets were installed by my local dealer, and everything that the chain could/would make contact with has been cleaned.
I may be crazy but I feel like this sound started immediately after I power washed my bike (my friend told me he always does it and it's safe)
