I am embarking on what must be a well traveled road, a research project to determine which GS model is for me. I have a preference for airheads, but maybe because I have only owned a '78 R100/7, and currently own a K75s. I understand that some airheads have a transmission circlip issue, and are in need of an alternator upgrade. It is my uninformed opinion that the airheads are easier to work on than the oilhead models. I am also aware that some oilheads had final drive issues. I am interested in opinions, experiences, good and bad. What would you buy for under $10k and why, $7k? There appear to be many early airheads with relatively low miles for under $6k as the market seems to be softening. What resources are available to sort out the options? My concerns are weight, reliability, ease/cost of maintenance. I live in western Montana and am surrounded by thousands of miles of Forest Service roads. What am I missing? I am leaning toward the early R100 models, only because the R80s seem rare and expensive. Which models have what issues and what are the best fixes? Hopefully this hasn't been beaten to death or is a synthetic oil vs mineral oil topic.
I am willing to be pointed in the right direction.
Thanks in advance,
