Replacement carbs for 1100 ex 1980

[slideplayer]

Hi peeps, has anyone replaced the carbs on a 1980 1100 ex with a set from a newer bike ? If so can you tell me mods required, jet sizes, etc. It would be nice to keep the original airbox if possible, this problem of poor tick over and rough slow running is spoiling the bike. Any help would be very welcome. Many thanks.

The only carbs I am aware of are GSXR1100 carbs. Any GSXR carbs you find will need just as much work as the originals. They are larger and most likely will not work with standard a airbox. If the standard carbs are rebuilt PROPERLY and all other tuning aspects are addressed they work well.

Have you cleaned the carbs and installed new O rings?

Hi peeps, the carbs have been dismantled, cleaned manually by me 4 or 5 times, ultrasonically at least twice, new mixture screws and o rings, floats set at 22.5, everything else checked and seems correct, but obviously somethings not quite right. Al new ignition, new induction rubbers, vale clearances checked, compression ok, carbs synced every time they were remounted. Any ideas most welcome. Anyone else had the same problem? Many thanks.

GSX 1100 EX carbs

Hi here, does anyone know what the problem is with these carbs ? I don't want to completely dismantle them, remove buterflys etc, if it's not necessary. If it is necessary to split them for repair, where can I get new screw for the buterflys, o rings, etc. Thanks for the responses so far, any help / advice most welcome.

Check my signature for a rebuild tutorial. You shouldn't have to pull the butterfly valves. Just be sure to shoot water into the gap between the carb body and the throttle shaft to get the carb dip out.
