The wrench at Black Widow worked at ATK for over two years doing nothing other then rebuilding these motors. Black Widow is only 25 miles from ATK. Both places are close to my house. Cord is the wrench at BW.. He knows these engines very well. He is a perfectionist and knows exactly what to look for. These motors are different. They don't have case haves to split. The tranny slides out out w/o having to pull the head off. The jug is part of the case and some other different ideas.. Some items wear out quickly some don't.. Assembly problems were most of the issues w C-Dale. ATK does all the correct upgrades except one of the most important.. The big end rod bearing needs to be changed to a Z400 bearing and ATK won't do it. They are ignorant as they say it's not needed.. They are dead wrong!!!! The Dale bearing was a good attempt, but it will fail.. The main bearing in only the FX400's was a bad design also in 01. It will fail also.. Cannondale actually corrected that in the 02 year..
