I have a hopped up 2003 Fatboy And what would cause me to Crack the Primary Shoe only has about 2000 miles on it. The Crack runs on the top of shoe most of the way a&nbsp\\;cross.

And is there a stronger Shoe maybe like a roller shoe and if so any Pros and cons and where can you get it

Chances are you had you primary chain too tight, they are a bitch to adjust , I would highly recommend getting an self adjusting primary tensioners, I personally have used both the m6 hydraulic one &amp\\; hds spring loaded one either one is fine &amp\\; cost about the same
