So about 3 years ago I picked up a Hobbit pa50ll complete bottom end, a set of wheels, a subframe, gear box and rear pulley. Last year I picked up a Hobbit frame, a tank and a seat. The beginning of this year I rebuilt the bottom end with Dos race crank, bearings and seals. S few months ago Conan gave me a couple of Dr kits and I was able to salvage one. I started to put it together after I got the engine built.
