[Fot] Short Version: Harmonic Dampener Question

[Charly Mitchel]

This is interesting to me.  I disassembled a motor that was used in the 2007 
race season to see the same thing.  I too had purchased the crank hub 
removal kit from the same person.  This seems to be a problem with his kit. 
Is he redesigning the kit?  And is he providing the past purchasers with a 
replacement kit?
I guess it would depend on how knackered your snout is.  My dampener was 
still tight and the keyway was slightly enlarged.  I would imagine if you 
got a key to fit in snuggly, it might be okay.  Maybe this would be a good 
crank for a street motor that doesn't see as many rpm's.  My problem is mine 
is a long ended early crank shaft and there aren't many replacements 
available for it.
