ZXR air intake tubes...

[NDORFN]

Does anyone know if the tubes off a '92 ZXR400 will fit a '92 ZXR250C? They look almost identical but I don't want to find out they don't after spending the dosh. Also, in the area under the tank where the intakes vent to there is a little unit with tubes that run off to the airbox and carbs. There's one short tube that isn't attached to anything, it just sits there, possibly to draw air from the intakes? Or should it be attached to something? I noticed at the front underside of the tank there is a nozzle with no tube attached, I presume to let air into the tank as the petrol level drops... should I attach a tube to it and run it to the low side of the bike incase there's an overflow?

Hey, I have an 89 A model. Im not sure about the intake pipes sorry, might be worth giving some wreckers a call.. they might know. With my bike there was one short tube that goes into the top of the airbox, if this isnt plugged in then yr revs shouldnt be going much higher than 10k. There is a little valve in the front underside of my tank too which has never been attached to anything.. pretty sure its meant to be like that & has never caused a problem. air into the tank as the petrol level drops I most likely.

I wouldnt attach a hose to it but make sure theres two hoses coming from the fuel tap.

The 'air intake' pipes do fuck all. Possibly cools the carbs and recitifier a bit, but mainly jsut a poxy styling thing. I wouldnt waste my money, unless its just for aesthetics.

I think the thing you are referring to is a vacuum diaphram, and from what I can see (and have discussed with old man, and flatmate who owns said ZXR) is just for cleaner emissions. Bike seems to run the same without it. Somebody correct me if they actually know what it does.

Air intake on the C is on the left fairing right?

just get an old vacuum cleaner and use the hose of that, mate did it do his one and it looks as new!

Yeah the REAL air-ram is a rectangular scoop on the left fairing with a rubber tube running across to the airbox. "Air intake" pipes isn't a very accurate name for the tubes running through the tank but that's what people tend to call them.

That's what seems to be on it now and it looks like arse. Maybe they used the wrong kind of vacuum cleaner.

Cold air, not Ram air ;)
