I guess a reliable bottom-end with left-side Timken bearing and at least a
forged crank were too much to ask for...

  Just out of curiosity what makes the bottom end unreliable? They got
forged rods, likely all the shafts are forgings so the only thing in the
bottom end that could be cast are the wheels. Where does this unreliable
shit come from are all the bottom ends failing and I didn't get the news
or something. Damn I always get left out.



  nobody #1
never had a TC bottom end problem

 

There's been quite a few reports on the CVO Forum of scissoring flywheels
and associated inner bearings crapping out taking out the oil pump and the
whole bottom end...... primarily on the 110s and some 103s. Probably as a
result of hammerin' 'em. The guys ramping up them motors are reflogging the
flywheels first thing. Say they can't believe the chintzy materials they're
using OEM and the far end of the runout specs is unbelieveable if you're
unfortunate enough to draw one of them out of the box.

Perhaps I was a bit rash.  But HD has drastically changed the "tolerable"
run out allowance on the cast and "pressed on" crank/wheel set-up.  Leads me
to believe these cranks run out quite a bit more.  As with the cheesier
roller bearing, probably not a problem for a stocker or a stage 1, but hop
it up a bunch and you'll wanna weld that crank.  'Least that's what I
hear...
