kz400 carbs probs

i just bought a 79 kz400 that has been sitting since 89 i got it to start and run off starting fluid but the carbs are very dirty and corroded does any company make an intake to covert this bikes to a single carb?

why not just rebuild existing carbs?

i have a feeling that i will have problems getting it to run right i havent ever messed with an engine with two carbs

i took a close look at them tonight and they are too corroded to rebuild what route should i go?

i might have a usable/rebuildable set,ill let you know tomorrow

ok so i bought a set of carbs that were taken off a running engine and put them on tonight still the same problem runs until starting fluid is burned out... my boots are cracked could this cause the problem? i put silicon on them to try to temporarly seal them to see if that was it and still nothing its getting fuel to the carbs though where do i go from here?

have you tried cleaning/rebuilding the petcock to make sure youre getting fuel?
if inside of tank is full of crud you might want to clean it out really good and install an inline fuel filter also

the pet cock flows fuel but to be sure i took the tank off my tiller and tryed it and still nothing at all im starting to get discouraged from this project

if the boots were causing the issue it would do same thing with starting fluid,did you actually see the other bike run?
or was it from ebay?everything on ebay came from a running bike,problem being that they dont tell you its been 5 plus years!

the carbs came from ebay.....off a newer snowmobile, and i was wondering if maybe the boots were cracked would it suck air through the cracks intead of sucking fuel from the carb into the engine?

Pic of the carbs.
Or reference to the ebay listing (perhaps the item number).

Good Fortune!

Whenever I see smowmobile carbs used on a bike, they often specify different fuel inlet valves. Apparently snomobiles use a fuel pump or some such thing that requires the carbs to be modified. They sell snowmobile carbs in dennis kirk, but even they specify changes need to be made.

There are threads on the KZ400 twins forum on doing single carb conversions. They seem pretty popular since the parts for the 400 carbs are getting scarce and expensive. (Factory diaphragms are over $100 buck now.)
