What is it and do I need it?

[kakapo76]

Hi everyone, pulled thefront fairings off to fix a crack and replace the rather crap bulb in the ZZR 1100 and found that i appear to be missing something- its part of the air intake assembly (see first pic) and is missing on the right hand side (when you are facing the bike).

What is it? and what is its function? can I get away with out it? Its the black bulbous thing on the left I assume there are meant to be 2?

Finally does anyone have a reccomendation of a good wrecker for Kwacks of this vintage (1995 zzr 1100 d5), I think there are a few bits an bobs that i need to find.

cheers

Roddy

for a start that's left.

everything you diagnose on a bike/car/plane/boat/train/bus/unicycle/horse is spoken as though you are piloting it.

for a second is it part of the air intake?
if it is, then yes, if it isn't, then probably not.

I bet you can find a workshop manual download for free on thinternet. That will be better than getting advice on here,

That is an intake resonator. It has two possible functions, the first is to dampen or tune intake noise, the second is to fill in holes in your torque curve. Being a Kawasaki, with their addiction to intake roar, it's possible the first is the case. The only way to know for sure is back to back dyno runs with and without. It's definitely nothing to worry about though.

Fair call, wont do that again.

what he said, its just to cut down intake noise, throw it in the bin.

late model ZX6R's have theirs mounted on the bottom, so they can fill up with water

Thanks guys, I have removed the other one to "balance" things and will add it to a growing pile of "if I ever sell it parts".

Make sure you plug the holes though otherwise it'll run like poo, you can see the bowl pressure tubes in front of the intake-noise-killing-satan-device and any leaks behind them make them run like dick.

fuck man, full off usfull info aint ya and FWIW

I am pretty sure they are actually RAM air intake tubes and are plumbed completely seperately to the air going to the airbox/filter. I stand to be corrected but thats what the manual states. Cheers for the input, I will block them off anyways to help get a smoother airflow anyways so no harm done :-)

Pretty certain the smaller ones are there to pressurise the bowls that's how the ZZR600s do it

OK, I think you must be right, :hug:

however, given that the smaller tubes take their air from in front of the main intake how does the holes further back have an influence? the bike has been missing a resonator for awhile now (apparently) and as far as I can surmise there might be a slight pressure loss from the open hole on one but that should be balanced back out by the airbox- the c models only had one intake in the nose so I wonder if that was a reason to change?

Thats my 1.5 cents

Thanks for taking the time to help a newbie- appreciate it.

ram air to where? the head for cooling? wip the tank off and you will soon find out where the carbs sorce their air from, Id expect going by the serge type tanks they do feed the carb or are those tanks (one in your case) plumb into the small pipe within the shrouds?

Yeah I take your point those tanks appear to be totally isolated from the two smaller tubes (which actaully "y' into one and head down the right side of the bike to the rear of the carbs) so it still begs the question will the holes left behind by removing the resonator tanks actually do squat? If those two holes are critical then I probably had an issue that needed resolving either way.

I'm not completely sure if it'll effect it much, but I'd have those resonator holes blocked off as you will have a wee bit of pressure difference between the bowls and airbox, it may lose a wee bit of power. On the 600s it destroys any power above 4-5krpm when there's even a small leak on the ram tubes

ram air to where?

To the airbox of course.
