Zephyr 550 carb issue

- Balls to the walls, sideways all the time
Thinking Ive done plenty of carb work on my kz, I can figure this thing out.
The air box had two pieces of foam held by silicon to work as an air filter. So I took the air box out and plan on re-jetting the bike for some pods. But until then I have nothing on the carbs.(Dangerous I know)
I got it running but wont rev anywhere over 6k.
Jets problem?
If so I may have a second bike ready to rock for summer after some bigger jets.
Any opinions?

Ive got this zephyr 550 (w/ a title!) off craigslist for 350 bucks.

Jet problem? :laugh: You think!
You absolutely must have some form of permanent filtration for the carburetors. Something oem/aftermarket designed for those carbs/bike.
Otherwise you will destroy the rings/cylinders.
If you change filters you need to change jets, so find something your going to just leave on there.
It won't rev because its way too lean without filtration.
Get the air filtration, then you can start fiddling with jets to find the ones that net you the most power.
Good luck!

My main problem is she bogs (almost a whoof/whoosh sound through the intake) down at 1/4 throttle, and stalls. if I can manage to get it up past the 3k mark at 1/4 throttle, it'll pull up fine on the stand (in neutral).
Oh, and (with the pods off) noticed that the slides kind of fluttered in the 1/4 range.. didn't open up smoothly. Almost like it just couldn't do it. Not enough vacuum to lift properly?
Haven't tried riding the bike yet though..because it's just not consistent enough.
I'm assuming you have CVK30s?
