I broke in my contour (from 19 miles) the same way and it's got 102 thousand now and I rev it to redline every single day. I know it goes against the grain but it works. Once it's warmed up I have at it.



Yeah, but that doesn't mean that breaking a motor in the 'traditional' way is necessarily wrong either. Many more people have been doing it the 'traditional' way for many more years, with no problems. For me, I like to err on the side of caution. I'll go with what's tried and true over something which 'may' work well for some...
