Hogasm I feel your pain. I've been there twice with the same motor. Go to page 8 of twin cam section. And check SE 103'' blown motor. My bike did it with just a stage 1 and exhaust @ around 4,200 miles. Then I built motor up 117hp/114tq and it happened again around 4,700 miles later. Both times where covered under warranty. The dealer put it on the chitty stock bearing both times. He replaced the crank this last time with a SE Pro crank at no extra charge & I went with the timken upgrade. Now it's a 113" @ 130hp/125tq so we'll see what happens next. I was reassured that w/ timken conversion & pro crank all will be good.
Is dealer covering it under warranty? I sure hope so!
Good Luck,
Grover
