valve noise
I just purchased by first harley 09 fatbob and have notice when riding there is some valve noise coming from the from the front cylinder. Is this normal? (my last bike 04 honda always had some noise)Just trying to see if I need to have the bike looked at. I'm new to harleys and don't know what to expect, but I really love the 09

Its hard to say with out actually hearing the engine. Is it always noisey of only when hot? My advise would be to let someone listen that knows Harleys. Depending on the mileage, maintenance and history, they have hydraulic lifters , BUT, they can sometimes be adjusted slightly and it can make a difference.

You don't tell us anything about the motor or any work that was done before your purchase so it can be hard to give you good advice. But.....
If the PO installed cams they may have installed adjustable push rods. These have a habit of coming loose after a while and need attention. I would remove the upper retaining clip on the offending valve's push rod cover. Push the bottom of the tube up to expose the bottom portion of the push rod and see if there are two 7/16th" nuts. One is for locking the adjustment and the other is used to adjust the length of the push rod.
I have noticed in my twin cam motor that the valves make more noise with the use of synthetic motor oil.
