Hello, I have always been fascinated with airheads and after reading a couple build stories (Raven's in particular) I want to get my hands dirty. I found the following on craigslist, "1974 PART BIKE (r75/6) - ENGINE IN FRAME WITH FRONT FORKS, BRAKE AND REAR SWING ARM - NO TIRES OR RIMS, TANK, HEADLIGHT, REAR SHOCKS, OR CARBS - I HAVE THE PINK SLIP - MOTOR 13000 MILES WAS RUNNING WHEN DISASSEMBLED 3 MONTHS AGO." and I am seriously thinking about buying this and making a offroad/GS sort of custom job. My question however is as follows, will this frame/engine/FD accept the later GS (R80G/S, R80GS, R100GS, or otherwise) subframe, tank and other little bits and pieces in order to turn it into a bitsa GS? For an oilhead man such as myself it seems that not too much changed throughout the years. If this question is stupid and/or shows a lack of serious research also let me know.
