used to be if you wanted one you had to make it. My kind of stuff. MB's are not something new used to be rough casting sold to make your own engine now that would weed out a few builders and no net for questions only mail. Look at us now!

I have been putting motors on bicycles since I was 8 years old, the kits do make some of it easy but all in all I always want something special/custom so it just helps, but I always end up fabbing a lot of stuff anyway. This forumn is a more valuable resource then that book, but I'm downloading the book anyway!
