This one has a link on making the flaps, and Harm had success just epoxying them shut. I personally just find ones in good condition and try to go over them carefully. In the future I might try out Harm's idea by making solid plates that replace the existing choke slides.

Those missing flaps went somewhere, like into your motor. This may be why the price was low. Its possible that it could be wedged at the back side of the intake valve. But most likely rattled its way around on the piston/ head before going out the exhaust valve. The piston, and valves could be damaged somewhat, along with the chamber in the head. Maybe a compression test would be a good start, and while you got the plugs out shine a small light down the hole to have a look.
This was exactly what i thought when i noticed they were missing.lol. "oh boy i wonder where they managed to go". I will definitely take more of it apart to inspect, it appears that at least the valve cover was removed once before by the sloppy application of gasket sealer. The reason the price was so low mostly was because the bike wouldn't start......he had broken off the positive battery wire terminal and jammed the bare wire in the bolt hole on the battery terminal, and there was a snapped wire in the main harness around the head tube.
Thanks apbling, that's probably what i will end up doing.

I always give this one warning since it's the one thing that gets overlooked on 550's (and other hy-vo camchain KZ's): You must release the camchain tension while installing the valve cover or you risk damaging the chain, tensioner, and guides.

You may want to do the compression test/ check you valve clearances/ lube your ignition advancer/ clean those carb's really well, set the float level and bench sync them when there off, look at the intake manifolds as these like to crack/ seperate causing vacuum leaks. Also check your valve timing, and make sure your guides for the chain look like there in good shape. There is a measurement for the chain length in the FSM.
I bought a 1000 that "Wouldn't start", dead in three holes, they had the valve cover off and forgot the chain guide in the inside of the cover. Chain jumped and got the valves.
Its just when you first get one you don't know until its checked.

thanks for the advice, i have a strong feeling that i will be pulling the bank off again anyway, but i will be ordering a set of the airbox hoses from z1 for the next time it comes off. Seems like the bank comes off a helluva lot easier than it goes on.
I only briefly ran it after i sorted the wiring problems out, and noticed the fuel/carb issues. Ill probably put the tank on and fire it up tomorrow and check the carbs anyway, see if the cleaning helped as well as "fixing" the choke plates.
