I'm trying to find out how much the front end compresses on a basically stock 82 shovelhead with hardtail, 5 gallon tanks on the stock FLH front end. I'm getting ready to start fabricating my hardtail and I want to make sure I don't build a dive bomber. I'm thinking 6.5 inches ground clearence in the front and 5" in the back should be enough. Cone motor, so no squish bike or around the frame exhuast routing to get in the way. Also, is that too close to be able to run floor board? I like floorboards and I don't freak out when they scrape, but I don't want it to be dangerous.
