Hi Fellow Bulleteers:
My 2004 Bullet 65 had 3 sprag failures. Needless to say, it is no longer in my bike. Upon investigating inside the primary, I found that the drive gear is in direct contact with the crank shaft. Leaving the sprag cluster in the primary means that cluster of gears is spinning every minute the engine is running. I didn't want the risk of more gears breaking teeth and dropping metal chips in the primary. Some may have avoided this but my sprags failed while I was riding, not when the bike was being started. I also wanted to remove the ugly hump on the inner primary so I got the kit from Hitchcocks and replaced everything, to include the inner primary and gears etc. There is some drilling and tapping of the side of the crank case. It was nerve wracking but I was able to complete it successfully. No more sprags, Better bike balance and best of all, the bike is almost 25 lbs lighter. As the Brits would say, "it works a treat"
