Hi Wayne, going into "Production Models" on the website, under "Carburetor I-II (Keihin)" and "Carburetor III-IV (Keihin)" there is brake hose information....... !? About the only thing i can say about that is, years ago, i loaded all the info i knew into the Engine Group and Chris loaded all the information he knew in the Frame group.
I do see in "Tech/Restoration Support" i have pics of my 232's carbs as seen in fuel system. Not alot of info there. unfortunately, my carbs are not able to in my hand for inspection because they are on the bike. 232's carbs would be the same as any other early type carbs on earlier vins.
The one distinguishing feature is the brass with tubes pressed in and parallel with the float bowl joint surface.
Looking in "Distinctions" in DB, #12, states 66 mm choke arm up through vin 1120, then 52 mm thereafter. One of the problems as i was compiling this Distinctions list was that, while i had 232's parts in my hand, 4363 was already an assembled machine. So i was not inclined ot dismantle 4363 to examine and compare parts for differences. That's where Vic has truly become the "expert" because he has seen so many of these different range vins separately and together at the same time. That's why i have relied on the observations of the members of SOOC to write in what they find, so we can all benefit through shared observations.
So, if other members have observations they can share between differences in parts, that's helpful. and very much needed.
And in Mark's meticulous documentation on #97, i am assuming there are some differences distinctions as well as other member's builds that have not made it into the 88 Distinctions list which is now probably well over 100 distinctions.
Wayne, you've taken on a monumental job producing stellar results. Bo should be proud his row of machines will grace SOOC's introductory web page. i was visiting with Vic the other evening, he sends his highest compliments to what you are doing as well as his regrets he can't be involved. He truly supports the club, but on the other hand, he is kept very busy with work.
