Again with the zx9 float bowl mod thing

I found it cheaper to buy the pilot & main jets from the USA>

I happened to have a Honda XR plug socket laying round which works great for a ZXR/ZX9>

You can type either of these numbers into ebay to possibly find a bargain?

Great! You're saving me a lot of time here fellas.

I'll see if I can find one at repco or supercheap. The bike has newish iridium plugs so if it's all too hard I won't bother for now. I may never have to change a plug. There are other ways to tell if the bike's running lean yeah? The blip test?

I think the stock main jets are 160 and 165. Guess I'll have to have to pull the carbs out and check it. If that's the case, could I just move the 2 165's to the outside and get 2 170's for the middle carbs? I'd be lucky if that were optimal, but with larger jets it's gotta be an improvement, assuming the bike's current setup is what it is.

Maybe it's best to put the bike back together, check that it's running about the same as before the mods were done, and get it checked professionally. I'll try the WA forum for that.

The hoses come up in between the intakes, although they're technically below the height of the filter they are on the clean side. You don't need any filters on the end of the float chamber breather tubes, most bikes do not have them anyway.

If I'm reading this right, you're trying to say the underneath side of the airbox where the ram tubes go in is the filtered side? It isn't. The air flows up through the air filter and clean air comes out the top side - which then goes over the carbs and then through.

The stock ram set-up has a filter on the balance pipe. Whether it's "necessary" or not is kinda subjective, but I'm running one on mine and it's fine.

My ZX9 runs a K&N fliter, Factory Pro 4 deg advancer, Muzzy 4-2-1 headers (off a C model) and a cut down Micron can. I got a Factory Pro jet kit and sent it off to the dyno. From memory my dyno guy ended up drilling out the original main jets because the FP jets in the kit weren't big enough. It pulls pretty hard from just about anywhere.

No I don't know if I'm explaining it well enough, the short tubes that I run from the float vent Tee pieces end up entering the airbox in between the carbs 1&2 and 3&4 and come out on the clean side. Although they are below the level of the filter they are on the clean side as oppose to being underneath the filter The little canisters aren't filters per se, they are baffles to reduce any pulsing from the position of the pipes in the Ramair tubes, when the Tee piece vents are run into the airbox any pulsing is massively reduced by the air passing through the filter acting as a baffle.

I think you are confusing us more now? You mention the vent tubes enter in the clean filtered side but then you mention pipes in the ram air tubes? What pipes are in the ram air tubes?
What exactly are the baffle/canisters?

Can you get some pics???

I think I get what you're saying now - but using the KLEEN port or the crankcase vent port on the airbox would be pretty much the same / less work than drilling the airbox to run the individual vent tubes in.

And the canister on the original vent pipe is a filter because the pipe starts at the front of the ram tube with unfiltered air and it needs filtering or the carbs would (eventually) fill with dirt.

But yes - if you can run your vent tubes between the carb intakes they will be on the filtered side of the airbox.
