[Shovelhead Bob]

Capt.Bob and CT_Duke, That "Bang" that you are referring to is called "Starter Knock", and is is inherent to the requirement of the ECM to get the motor up to speed and running quickly.... The sound you are hearing is the compensator loading and unloading rather quickly.... More noticeable on the Touring bikes, as the Primary is designed a bit closer than the Softails/Dynas.....


Additionally, CT.... Why don't you tell me the Tech Tip number, 'cause as far back as I can tell or go, there is no such "Advice" or recommendation about the tranny whine..... That is a design characteristic that is inherent to Straight cut/Spur gears, and there are NO differences in the Softail transmission as compared to the Dyna or Touring Transmission internals......
