You have to be careful with the trees on a stock Bike. A lot of custom guys use the rake trees to bring in the trail to an acceptable measure after they cut and stretch the neck, downtubes, etc. It you put raked trees on a stock neck you will offset the trail to unsafe levels if you go too far of a rake. Just be careful with the raked tree setup is all I am saying.
I know Bob Scogins has gone over the Springer front issue a few times here on the boards. He tried a few springers before realizing that it would take a custom made springer to fit. I think he ended up going with a stock Harley narrow glide front-end that he customized to fit.(correct me if I am wrong, Bob, if you are still lurking.
