Appreciate the support guys... My only other experience in dealing with older things is turn of the century .22 caliber rifles. My approach to them was to find ones that were well past collector condition, missing or broken stock or, parts, shot out bores, etc. I then return them to good looking, function rifles. I find myself looking at the 71 with the same sense of respect. My original plan of swapping engines included powder coating the frame and related parts. Additionally replacing rims, spokes, chain guard, ignition, charging systems, etc with aftermarket parts and updates. My approach to the 71 was going to be the same as the old .22's. Which is how I really like to do things. Not a purest but respectful of what it is. If the bike was in a worse condition I would have no problem marching ahead with my original plan. But it is not... Think I'm going to sleep on this for awhile.
