Two Nebraska builders combined their talents to construct a machine for the Born Free 6 general crowd. A new approach to a divorced Ironhead project has been implemented and has proven effective when the bike was ridden into the BF6 show. The BF6 "Shortster #1" is in a frame with two shelves -- big twin style. Instantly we realized the possibility of modifying a stock XL frame for the big twin 4-speed. Cut off the tumor! Damn good motors, pain-in-the-butt clutch and tranny. Leave the motor together , divorce the tranny, follow our slide show and PLEASE TRY THIS AT HOME! Tons of old Ironheads ('76 and earlier) are sitting around that have compression but also a blown transmission. Everybody knows that! Sawsall, jigsaw, cutoff and flap wheels. Learn to use a file and rotary files and burrs. Properly drill and tap a hole and drill one hole through. Learn basic geometry and welding. The marriage of these 4-cam engines to a big twin 4 speed combines two of the best components to ever depart the factory. The photo album shows divorcing empty cases. Much easier than an assembled engine. We have developed a front belt pulley to mate with the 4-speed. We also have additional parts under development to ease the conversion. The 4-speed kicker gears have more torque and less travel than the XL so stay tuned for a kick starting report---should be easier than kicking the XL. Our BF6 #1 utilizes a RSES electric start. GOAL--$5000 hand built choppers.
