1998 Gsxr 600 Vacuum Diagram

1. I am having difficulty location diagrams/function information/etc for my lift control valve body and other emmisions control equipment on my engine [1996 gsxr 750]. I have a Clymer manual and I have been looking through it, but it is just not that complete.

   Anyone have a link or know where I can view what these parts do, where they are located, etc, as some of the emissions control equipment is missing on my bike.

   Thanks!!!

3. PM Sent. No discussion on how it all functions, but really good breakdown on how it all goes together...

5. Basically you have hoses that supply air from the airbox to the exhaust (right after the exhaust valves). The fresh oxygen allows the unburned fuel to continue to burn as it travels through the exhaust therefor reducing emissions output. The emissions valve shuts off the supply of fresh o2 when the engine is under vacuum because it causes violent backfires and is hard on exhaust valves and seats. The valve is either closed via engine vacuum or electronically depending on the model and year. The old stuff was always vacuum. The new stuff is usually electronic.

   I wouldn't worry about the emissions equipment missing. Install block-off plates and plug the supply outlet from the airbox and your engine will thank you. A malfunctioning emissions system will create destructive backfires that can be annoying and more importantly destroy exhaust valves and seats.

6. just cap it off or rip it all out.

7. I'm pretty sure that the SRAD used the same PAIR system as the hayabusa does.

8. yeah, the SRAD does use the PAIR system...THANKS!!

9. The 96 GSXR doesnt' have a PAIR system unless you have a California Bike. It wasn't til 97 that Suzuki employed the air injection system on their production bikes. You can use this to your advantage if you do have this on your bike.
   Rout the Crankcase vent from the top of the case directly to the Pair valve instead of routing to the airbox. On a open class bike, it can be worth about 4 hp.
   Trust me. The AMA tried emposing a fine to Jake Holden because of it.

10. FRICKIN SWEET!!:mrgreen:

    But, the previous owner ditched all of the PAIR system...at least as far as I can tell...the lift control valve bodies are missing, the threaded holes where the PAIR system connects to the exaust ports are there and the conector for the solenoid [for the lift control valve bodies] is there, but no solenoid.

    Thanks again!!!!

11. That sounds more like you have a bike that did not come equipped with the PAIR system. If the ports on the front of the head underneath the exhaust ports are not blanked-off, they are most likely not active. Suzuki did the same thing on the Bandits and other bikes where they used the same casting for the heads, but only machined the holes in the ports on CA models. If your PAIR system was functional and those ports were un-capped like that then it would shoot fire out of them while the bike is running.

12. 
    Think I figured out my next mod, lol. :mfclap:

13. That is the thing, I think you are absolutely right...about the effect of not having an original, factory-installed PAIR system....what is missing for sure, are the lift control valve bodies....do you know what they are/do?

    The previous owner wanted a track bike, and thus removed them and their hoses, and simply capped the openings on the "tops" of the carbs on the other end from the float bowls.

    I did see, drilled in the frame, where the carbon canister would mount to if it came with one, IF it was a CA bike, but I really do not think it was, on account of the lack of flames coming our from where the threaded holes are right below the headers.

14. I'm not sure that I understand what a "lift control valve body" is. It almost sounds like you're describing the air-bleed valves like Keihin likes to use on the Honda carbs - but the way I am remembering the early SRAD carbs, they didn't have those.

    ...the only other thing I can think of is the old "slingshot" carbs had fittings on the bowls that went up to the carb-bodies - but that's a completely different carburetor from what you have as well.

    Do you have any photos or sketches?

15. Thanks Fast Cat...I am trying to find the appropriate pics of them....it is the same problem I faced before where nobody knew about them....however, the Clymer manual talks about them [a little, and not about function]. The best I can do at this point is this:

    http://hooked-on-phonics.com/Hooked...rID=6775732&ACBSessionID=D0119828552836197B34

    Scroll down to you can see the float cover, then you can imagine the little "turret" or armored gun looking thing that is not labeled on the float cover...that is the part, but it is very hard to find anybody that sells it/talks about it/etc. But, I am looking...

16. Dude, hooked-on-phonics? :scratchea WTF, O?

17. OMG!!Sorry...wrong link!!! Jiminy Christmas...SORRY!!!:scared:banghead:

    I don't have the correct editor to draw an arrow on this pic to show exactly where it is....but it is directly above the word...AH HA..just got it...the above link to hooked on phonics was NOT even any kind of joke, pun, funny, whatever....a COMPLETE MISTAKE.

    

    OK, so hose #36 connects the void/vacuum/air in the top of the cover #34 to a hole on the float bowl, which then connects to the lift control valve body [arrow]. there is one of these on all of the float bowls, then they are connected together with hoses and a solenoid [not sure what fuction this solenoid does in this application], and then it matches up with the PAIR system...I am spitballing a little bit here. I am positive that the connection where the hose #36 connects to the float bowl on each carb, does not actually connect with the fuel in any way. That is, the connection/hole into the flaot bowl assembly, is separate from the fuel bowl chamber[with the needle valve etc.

    Part #44 is a solenoid, but I cannot tell if it is the one that connects the lift control valve bodies, and #43 is a vacuum transmitting valve.

    On my current setup, the four hoses #36 are connected to the float bowls, but, the opening to the outside is not blocked at the lift control vavle body is not there.
