Been done a time or two.  Yonuh Adisi changed his out, but can't remember details.  Maybe WD had one too?  Also seem to remember Voodoo Vintage was designing one.

Should find some results if you do a search, just be sure to go back to "all posts".  I don't remember much recent talk about it.  

Keep in mind that all of the GS series have the same head tube dimensions as the savage.  So if you find one for that series, there's a good chance it'll fit the savage.  Might even apply to all japanese bikes, at least the early ones.

JUST wait voodoo coming out with something in the near future. been talking with them and their working on it. i 've been waiting also so i can finish my bike and move onto the motor

thanks the springer and peanut tank will finish off the the look i want ,and over the winter  i will bore and redo the cam

voodoo has a in house front end that they have designed with the rounded forks . i think it looks more old school then the squared
