I just got the Mad force. Let the engine idle through one tank of gas as instructed for break in. Went to run a second tank through it the following day and the clutch bell was frozen to the engine. Upon inspection I found the small needle bearing in the clutch bell ( the one closest to the engine) had come apart. Maybe it got hot from not moving while the engine idled all that time or maybe it wasn't lubed enough from the factory. I don't know, but in my opinion the bearings are way too small. A larger ball bearing would be much better.
