I haven't been on the site in a while so I am re-introducing myself... I have 2 COMPLETE and running 2-stroke 750-triple H2's (1973 & 1975)and a 1986 ZX600R Ninja... TONS of parts that I began accumulating back in 1980... engines, cases, cranks... SEVEN sets of expansion chambers! Does anyone have any idea what this kind of collection is worth? Thanks much
