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

There must be a pin stuck in the brake calipers of either left or right side. Does the car skid to one side on applying a hard brake or on releasing it?

ijaz bhai right now cng is all out and its cng closure days here.ill try and let you know here..i know its some air fuel mixture problem but cant figure it out where it lies!

Just to check this that when does it spins, I tested the car on an empty road.
Applied full brakes with clutch depressed at around 60km/h and this time the car spinned towards left side.
Tried it 2~3 times and it kept on going towards the left side, however the sway movement was very less and under control than the movement it did while spinning towards the right side.

Bleed the very ends of both the left and right front wheels. While pressing brake hard get someone to slightly open up the bleed screw on the left wheel and some fluid should quickly instantly squirt out. Then do same for right. Make sure bleed screw is tightly closed before releasing brake pedal.

If alignment okay, get camber checked for front wheels. Dont know if your car has adjustable camber for rear wheels so the wheels guy should be able to tell you about those.

Also, are you sure there is no free-play in the steering system?

Safety first! I think you should not drive in this situation until the problem is solved.

Have you checked whether your front wheels locks first or the rear ones on hard braking. Because if your rear wheels locks only, then your car will spin on one side. Your car braking balance, the steering and the road tilt will decide the side the car will spin.

Also if one of your front wheels locks and the other keeps rolling, it will force the car to spin or drift on one side. But the side will remain same if the locked wheel is same every time. A stuck caliper pin can be reason but it will wear out that brake pad within weeks of normal use and you will notice black powder on the rim.

12 years...! Either you don't brake a lot or your brake pads are rock solid (plus mirror-polished) so nor your pads wear out nor the rotor. I think the service manual says that when 2mm lining is left on the pads, you should replace it. Correct me please.

i changed my liana air filter when i low the race there is some problem with car car stops sometimes their is sound doup"

@Daniyal

Metalhead has pointed out the possible causes in an excellent manner, i have to appreciate that.

In addition to that see the following post of mine regarding the exact sequence of bleeding

Dont have the proper tools.
I'll ask my mechanic to check this.

No the rear have torsion beam suspension.
However I'll definitely get the camber adjustment done for front wheels as Im feeling that something is just not right with the allignment of my car.

Also, are you sure there is no free-play in the steering system?

Yup there are no such issues.

Im thinking of doing the same.
The accident last year was due to my laziness and negligence towards this issue.

Have you checked whether your front wheels locks first or the rear ones on hard braking. Because if your rear wheels locks only, then your car will spin on one side. Your car braking balance, the steering and the road tilt will decide the side the car will spin.

I tried checking this and almost everytime the car stopped normally and in time however it skidded two times on a similar patch of road (straight patch with no bend or inclination towards any side)
One time towards the right and one time towards left but this movement was very less and under control.

Also if one of your front wheels locks and the other keeps rolling, it will force the car to spin or drift on one side. But the side will remain same if the locked wheel is same every time. A stuck caliper pin can be reason but it will wear out that brake pad within weeks of normal use and you will notice black powder on the rim.

This is what exactly happened!
The car skidded towards right and when I went for brake service, the right side front brake pad was in a horrible condition and its edges were almost finished.
I'll open the wheels and then check the brake pads to determine their state.

12 years...! Either you don't brake a lot or your brake pads are rock solid (plus mirror-polished) so nor your pads wear out nor the rotor. I think the service manual says that when 2mm lining is left on the pads, you should replace it. Correct me please.

I actually meant the brake lining (the pipes) from which the brake fluid is pumped.
Any way to check their condition apart from general inspection?

Thankyou Ijaz Bhai.
Will check it and then do it they way you have mentioned it.

[daniyalahmad]

As per my info it's 40L.I have never filled it to the full but after servicing the fuel tank when i filled 20L gasoline in it the fuel gauge shows half tank exactly.

Mine is definitely not 40L, with almost empty tank it got full with 27L (fuel gauge showed 70%) so it should be around 30-32L. So may be your car has the standard version and mine has the smaller fuel tank.

Any body with PS suzuki khyber SA310 user manual may help.

It can hold 33 litres.

Im having a feel that it is due to some allignment issue with the car.
I got the wheels balanced and the car alligned a week back.
The workshop was too crowded.
The guy who worked on my car was not a regular, he inspected the car and after 5 minutes asked me to take out the car.
After that the car was not used for 4~5 days.
Last sunday I noticed this while driving on the highway that I was unable to leave the steering wheel for even 5 seconds, because even if left for 5 seconds the car would move to the left side to this extent that both the left wheels would be in the other lane.
Also the steering has become too much soft which becomes quite scary at high speeds.
Will go back to him tommorow Insha-Allah and will tell him to check it.
Will let you people know that if there is any betterment.

Hey everyone!
Need some help.
Whenever I depress the clutch of my car, there is a feel of friction in the clutch pedal. (As if the clutch wire is not lubricated)
Now as per my knowledge, the wire is okay because when I turn off the engine and depress the clutch then the pedal smoothly goes all the way down and comes back up.
The wire was changed last year with the best one available in the market.
I've checked the clutch cable and it is not touching the mats or the floor insulation/ carpet.
Also I would like to mention here that this friction feel increases if the clutch is pressed with engine at high RPM.
I tested it with the AC switched on and with the accelerator pedal pressed and the friction was directly proportional with the increase in the engine RPM.
Also the shifting is not that smooth.
What could be the possible reason for this issue?

Any idea about this issue people?

[ahsanonline]

The side which has a more worn out brake pad is the side that bites more. Check this side caliper pin. Also check the other side for air in the brake line.

Yours may be a camber + brakes issue. Get camber checked first. Competence of alignment guy really matters.

nervous steering is caused by incorrect toe setting.

@daniyalahmad

Regarding the clutch issue, it seems that your cable, its linkages and pedal is ok. As you said, you feel the friction, like there is some slight vibration in operation of the clutch. No extra force is needed.

IMO-The problem lies in the bearing. There is a thrust bearing in between the clutch linkage and the fingers(leaf springs) of the pressure plate.
When this bearing gets dirty, it will make friction like noise. When it gets stuck, the fingers will grind over the bearing face and will start wearing them.

I hope its not the clutch plate sliding on spline being dry.

Daniyal have you tried Wheel & Wheels in blue area?

[MoizIrfan]

My khyber slightly does missing on low RPM.have tried everything from plugs, tuning but all in vain.Now I have doubt on its cng kit relay. can it be the culprit:S

Ignition timing may be too advanced
or
Improper valve clearance
or
Mixture too rich

[smijaz]

Can any body plz share the amount of r12 refrigerant Khyber (1996) Air conditioning system should hold, it should be mentioned on the sticker near the radiator.

If any body could share a picture of that sticker, it would be great.

[Gregarious1]

Hi All,

People are expert here to do their work himself. Really interesting, but I can't do it myself. Yeah I can someone guide me thoroughly.

I have cultus vxli cng 2009, there is no tuning from last last year. Need to be tuned up n change the plague as well recommended by Suzuki Company while Free Inspection Unit.

Any good recommended mechanic who can tuned up my car?
