I'm no Expert but as far as the loop goes, all wickedinhere would have to do is bolt the engine in (a bit of work involved) and reattach the hardtail then to ensure alignment, Hopefully this works out for wickedinhere, I have a line on another titled frame and engine that will be virtually delivered to within 10 miles next month (hopefully) of me so go through with the deal your working on, but i'm always open to deals, money's tight but i'm working on 3 different XS650's now a Hardtail w/11" stretch, a Brat, an Enduro and 3 more in the planning works Trike, Tracker & something Crazy, anyways good luck to all & keep Rocking
