what bike r they off? do they have a choke?

Mark, he just used that picture as a reference. he doesn't have downdrafts. No choke.
I have a super set of 26s I'm boring that would work great on that bike.

yeah the pic was just reference. black i didn't find a set nor did i hack up the fcr...

what bike r the fcr's off?

These where off a 92 gsxr 1100 i have the engine too i might as whel just put that in my 750 frame lmao

it apears that those were not stock carbs for that bike.
i found this info. it would have had BST36ss carbs.

if u can make it fit, your bike would be a way better bike than it would with those carbs on the 750.
give it a go. :evil:

right on. Give me a shout

these carbs are a semi down draft design they wont work on a side draft motor like yours with out a lot of work they are designed for late model liquid cooled sport bikes like the zx-11 or large gsxr's fzr's that type of bike. the float bowl angles are completely wrong. plus they are way to big for a small 2 valve head like what is on your bike. you would be way better off getting rid of them and getting a set of 29 crs or 29 smoothbores or even just installing a dyno jet kit in your stock carbs unless your motor, head and cam combo is very radical
