This was/is a stock true/welded crank. I was there when it was true and made sure it was well past the "good" stage when I installed it. This was about pass 6 or 7 after we really got it running well. When this happened the bike was running the best it had, and 60'd it's best ever..........Bike nosed over around half track and came back to the pits vibrating so bad it would put your hands to sleep.
