Hello

I just recently picked up a big package of parts and 2 bikes. One is a zx7 with lots of zx7r parts kiehin flatslide 41mm carbs seller is saying a 950cc supersport motor with falcion lightened polished crank. The other is a true zx7r I believe (no ownership) that was involved in a crash and is missing carbs and a header.

Looking to possibly get some info on the carbs. I don't see a choke on it, is there no choke switch or enrichment knob on these.

Appreciate any input as I am pretty uneducated with these bikes.

Thanks

Nice find 馃槑

I recently acquired a 92 zx7 (J, not R) and have gone through it a bit, so I might be able to offer some help.

I spy an RC390 in the background, I have one too 馃憤

Awesome. Thanks man. Just got the carb un stuck and cleaned up. Seals look not bad actually, and a lot less evaporated gas than I expected. Was just wondering about the choke for this bike though, as im not seeing anything on the carbs.

And awesome rc390s are fun, it was my first bike. I got it out on the track last year, it was a blast, handled very well.

If it isn't too cold this weekend (Michigan) I'll take a look at what the choke cable connects to, though my zx7 carbs are going to be different than the zx7r carbs, I believe. I have a service manual at home that covers the 7r so I'll check that out too.

Beauty. That would be helpful, thanks a lot.

When you pull the choke cable, it pushes a piece of metal (like a rail) along the front of the carbs to pull out or push in the choke plunger thingy (technical term)

Here's the cable (carb 4 is on the right if you're on the bike). I couldn't get a good picture of the rail the cable attaches to, but it's on the front of the carbs:

Here's the plunger/rod it pushes and pulls in/out (left side).
The "rail" is the steel piece hooked on to the brass rod:

And a pic of the right side for good measure:

The service manual had pretty crummy line drawings, I couldn't find a good image of the choke.

Thanks for the reply, it looks like my carb is a different settup entirely. Also looks like I'm missing an airbox. good to know what the stock parts look like. I will have to inspect where the linkage goes. I didn't have to disconnect anything when I removed the carb I know that. I will probably have to look up the carb specifically probably. I looks like it has a little fuel pump going into the carb as well.

Yeah, those look fancy. There definitely is a fuel pump and an airbox. They also refer to an additional "accelerator pump" in the manual. I think it kicks in when you give it the beans.

I wonder if they ran with a custom airbox: Race Airboxes | Andys Kawasaki ZXr/ZX7R Tribute Website
Ah so they mentioned these Carbs in this article. These are fcr carbs It looks like. But they just got rid of the airbox completely instead of modifying it.

Interesting. I wonder how they started that thing, maybe it's just set up for it, maybe they used a roller starter. Mine definitely needs choke to start but is happy wihtout it after ~60 seconds or so.

The one with the fcr carbs is the 950, right?

It doesn't appear to have one. I have seen videos of some fcr carbs being cleaned, and the one (out of a Kawasaki dirt bike) had a choke on it, so I was just confirming if anyone has any input on that.

Awesome, let us know how it goes. That's a cool bike for sure!
Got it fired up. Carbs were seized got them moving and cleaned out. Tank was sitting with gas for 20+ years so put the other tank on. Changed filters, lines and swapped the fuel pump unit from the other bike. Next is coolant. All new hoses for that, drained out alot of nasty stuff. Going to need a really good flush.
