    Default Self Tuning - Khyber G-10 (Plugs, valve clearance, spark gap etc)

    Salam

    dear members/experts

    I own a khyber 1996. Recently overhauled its engine completely at home by myself except the mechanist part. It has its first oil change at 1100Km yesterday and i am planning to tune it. I have following query for the learned members/experts

    Q.1. recommended spark plugs for khyber g-10 on CNG
    Q.2. Recommended spark plug gap?
    Q.3. Recommended tappet setting Hot/cold?
    Q.4. Running was on petrol with Caltex Havoline formula and now i have switched to CNG with Shell helix HX7 10-40W (synthetic) , is shell HX7 ok?

    What else should i do or check to get max output and efficiency from my g-10?

    regards


    after-note: In addition to the above queries, this thread also contains info on carburetor, AC, electrical, cooling system, brakes & gear issues related to khyber G-10.

    Special thanks to following experts :

    well I was unable to locate the vacuum valve so fixed the leak with depoxy as shown in the above pics.
    These pipes were connected with each other which I suppose is wrong .
    Found an empty space for vacuum pipe as shown below don't know where to connect it

    Also the thing marked in square is missing

    I haven't got AC in my khyber.
    My primary objective is to Increase rpm when Lights or radiator fan engages. which I have failed.
    Suggest me how to connect these vacuum pipes. also any settings for the amount of rpm increase when electrical load comes

    that electric thing is the vacuum solenoid for the idle up when you switch on the headlamps or when the radiator fan runs.

    Its a simple solenoid and almost any type will work, If you cannot find a genuine one then get a generic one from a toyota and fit it to the body of the car, one side of the solenoid connects to the vacuum fitting with the missing pipes and the other side connects to the vacuum pod behind the carburettor in the picture which is missing a pipe.

    The wiring for it is near the shock tower - trace it out, you will need to cut the connector and extend the wiring if you use a toyota type vacuum solenoid.

    The rpm adjustment on headlamps etc is on the little rod that extends to the butterly arm (throttle shaft) - use a screwdriver to adjust it with headlamps on.

    Thanks now I understand the connections. Now I the only thing I don't know is the rpm adjustment rod that extends to the butterly arm

    look at where the rod connects to the carburettor, there is a screw there - turning it changes rpm as required. It only changes about 100-150 rpm.

    When in original tune the headlamps, rad fan or A/C do not affect the rpm on a khyber. it idles at 950 rpm all the time - just like a subaru E10 engine (I love that engine, its a fully forged suzuki G10)

    The two green arrows you made.

    left side = secondary throttle opener
    right side = headlamp idle up vacuum pod

    the blue arrows point to vacuum pipes

    the secondary throttle directly connects to the carby in the picture
    the pipe going to an electric switch and then to the headlamp idle up is just that "the headlamp idle up"

    When you switch on the headlamps or the radiator fan kicks on this solenoid energizes and raises idle speed by sucking on that vacuum pod.
    Thnx Xulfiqar bhai, i will connect these pipes my self. I also bought the best fuel pipe available in market, the guy said its german pipe used in mercedes (which i think he was exaggerating) but the pipe seems good. cost me 100 Rs/feet.

    fuel pipe? you need vacuum pipe for this job and mercedes dont use rubber vacuum pipes they use very hard nylon pipes with little rubber pieces on the end.

    just changed the fuel pipes my self, the vacuum solenoid had no electrical connection so have to lacate its wiring first.

    Cleaned the carb with carb cleaner, converted fan from direct to auto.

    @ xulfiqar

    where does the circled pipe connect.

    while checking whether the fan is working on auto or not, i noticed white smoke coming out silencer, it was more than usual i guess.

    is it ok or there should be less or no smoke.

    This connects to a port on the carburettor body - its a very short pipe - about 3 or 4 inches only. The vacuum solenoid wiring is very simple, it has a direct ground but a switched positive, it must be lying close by, usually near the shock tower.

    burnt oil - check your engine. Running too cold will cause that too - you need to run it hard to clean out the exhaust.

    As Im not there in person I can only assume its oil smoke. You can smell it and test. But one should only check after a long run.

    No don't have one in PDF form but have the book which came with the car.
    I once uploaded it here but now have lost the link to that thread.
    Tell me which section you want and I'll upload it.
    One of the most difficult things in the world is to know how to do something, and to watch without comment, somebody else do it incorrectly.
