This is a 1967 Donnie Smith worked Sportster frame and Donnie Smith girder front end with a 1973 XLCH engine. Some of the mods to the engine include a Karata drag belt primary set up, a Power Arc electronic ignition and S&S Super E carb. It is kick and electric start. The front brake is an old Hurst Airheart, the shocks are progressive, and it has 2001 Wide Glide handlebars. Pretty much everything else on the bike is 35 years old.
