I'am a new member and been reading this forum for quit some time and have a question I would like to put out there. I have 06 street bob and recently put a 95" kit in with K.B. piston, andrews 32g gear drive, s&s lifters and adjustable pushrods and powercommander usb3 and done head work as well. My concern is I have some low rpm knocking/rattle when I take off or lug the motor, and also some valve train noise. I realize I will have more noise with the gear drive set up but anybody have any ideals where to start? Bike runs and performs good.
