Okay, motorcycle gearheads, I need a little help here. Are there any Harley carbs or other cycle carbs that use a "down flow" design? (Like an automotive carb?) I need FOUR one barrel carbs that are all the same...cheap, obscure shit is okay and encouraged...but besides Rochester monojets and Old Ford 1v carbs, what else could I be looking for? I thought maybe some bikes might have used a down draft style carb...anyone know...or have anything? Yeah...I'm up to no good...or as my hero, Fred Sanford once said: "I'm way past No Good, I'm at Downright Evil, boardering on Treachery!"
Lots of English cars used Solexe and Zenith downdrafts. The carbs are still fairly easy to find and cheap too. I can't think of any bike jobbies at the moment.
i've been working on bikes for forty years.......can't think of anything that has down draft carbs, some Hondas like the v-45 have maybe, 45* carbs....oh ya, yamaha600's may have what you want but it is pretty much a one piece thing (four carbs, one unit) CT
Here's what 4 old Rochesters [235 chevy carbs] look like on an old hemi. I haven't fired it since I've owned it so I have no idea how well this setup works.
Like Nads said, Solexes would be perfect, pretty small. Four 40mm solexes(I think they had even bigger ones than that, 44 maybe), you can get them at VW shops pretty inexpensively. A freind of mine is puting one on an ironhead sporty. -Jesse
