Kz1100

Hi im new to the site,im building a kz1100 ,it needed a lot of parts .i found a rack of carbs on Ebay ,they were 34s in the description but they were 32s, they were cheap so i keep them i did fit them on the engine,they rev fine and idle great but on a cold start ,the engine take a few cranks to get it going,is this a common issue with the ignition ?or i need to enlarge the choke circuit or it affect the Pilot circuit .That is the project im in.

This is my project

Welcome to KZR

Welcome. Do you know of the enrichment circuit is 100% clean and functioning properly?

yeah i clean it,but i noticed the hole of the enricher is very small , almost sure is smaller than the 34s , but im not sure if it affect or is connected internally with the pilot circuit

Welcome.
Are you trying to get it to run without any air filters? Those old cv carbs are notoriously hard to set up with individual filters. Without any filters at all, they will be quite a challenge. KZs are pretty uncooperative when cold, even in stock configuration. Withe the carbs and exhaust open, all the jets will need to be increased in size significantly. Unless you have a wide selection of jets at hand, it might be easier to start with something like a Dynojet Stage III setup as base jetting, and go from there.

thanks didn't know they were like that,any mods to solve that problem because after it start is fine and starts back up with one crank ,it takes like +-5 cranks is that the same with 34s

thanks for the help,found the problem,the jetting was right ,i found a leak on the carb intake boot,a small crack fixed with a gasket,running great

Welcome Pabon.
Have fun, and ride safely.
