Yep, many, many, years, Honda sold about twenty five (I believe) 970 kits, and immediaetly tried to get them all back! of course they didn;t manage it.....I believe each kit cost approx 30,000 $$
And consisted of around two-hundred parts to fit to your bike, from the crank to the wheels and everything inbetween including footrests! I read a guys website that had spent five years searching for these parts and money was NOT an issue!
There would indeed have been much info that came with the kit.
If he has spent years collecting a full kit ( and this would be, read;" IMPOSSIBLE" now, Then obviousely he didnt start off with a full kit himself, therefore, he would have got "a bit here" "a little there" and he may at some stage (at a guess of course) come to meet someone who had a few parts with the original info maybe?
