I need all kinds of advises you can offer. I am planning to drive Karachi to Islamabad in Alto VXR 2010. I went to Suzuki Macca motors, they did 40 thousand KM inspection, over hauled clutch plate(pedal was hard to press), changed some hose pipes and changed weak ac and fan belt , they did tappet adjustment and charged me 41,000+ bill which I can also attach for forum viewing. I installed brand new tires Dunlop 165/70R12 77T. Mr. Irfan senior technician in Macca motors looks after my car.
i took car for test, the car became very smooth but car didn't go beyond 80-100km speed. The car is very good in acceleration both in CNG and petrol, it some time is difficult to guess if its running on gas or petrol. I went again 3 times to Macca motors, they rechecked everything the firing angle degree 10/20 for gas/petrol with timing gun, they said advancer is running good. i have carburettor car with advancer installed and CNG is company fitted. Tires were free, brakes were free, no noise coming from car and car is smooth but cannot go beyond 80-100km. Yesterday I again visited macca motors they sprayed can of carburettor cleaner and i took the car for 300km+ journey Karachi to Hyderabad and back to Karachi. the maximum I was able to touch with 2 person with Petrol and AC off was 101-103km/hr and the same result is with CNG. however car is very good in acceleration. I showed my car to local mechanic he also got failed.He removed the air filter in the end and let the carburettor open freely. Still I wasn't able to cross 100km/hr barrier with good acceleration in AC off with petrol. Today I again went to macca motors they sprayed can of carburettor cleaner and still result was same. Macca motors asked me to goto Gul plaza to Mahmood carburettor wala. Over there I saw a man came from Suzuki south and handed over 2 carburettor for servicing. Mahmood sb. said all Suzuki companies give us these jobs so we are very good in it.He give car a great race in neutral gear and saw high speed butterfly valve opening up and told me your carburettor is okay.Car gives no humming, jerks, misfire. Even Exhaust output is very good and water comes out from exhaust. We bought this car year back and I had took it in CNG 140-150km/hr and in petrol 165km/hr with AC off. My younger brother had driven it for a year all in petrol and now I have taken it he bought swift.After getting the car I didn't raced it up. i checked that 40k km inspection was due and I had to take it to another city, so that is why I had done all these works on car. Before giving car to Suzuki Macca I wasn't sure if it could cross barrier of 100km/hr or not. Anyway, the carburettor guy charged me 2300 and serviced it and I took the car on superhighway tonight in both direction so wind doesn't matter in final speed, I wasn't able to cross the 100km barrier.Even mehran 93 beated me with speed on super highway. Macca motors said your speedometer could be wrong but all cars were overtaking me. I need help, i have got sick and tired in 2 week and had spent more than 60 thousand rupees which includes new tires and all I get is 80 kilo meter per hour speed. My name is Syed Umar Farooq and number is 0300-2478118. i am waiting for car to get ready and want to take it to Isb as soon as possible, If this car get fixed with your help.I will leave for Isb in next hour.
