There was noise coming from the engine when we give acceleration suddenly... I gave my ride to sr suzuki, noida sec-2 for this complaint and they suggested to change the cylinder kit and gaskets.
I gave the approval and they changed the kit. But still there is noise after the first service.
After this i had engine misfiring issue. For that i changed the spark plug and even cleaned the petrol tank as per the service technicians demand.
After 2 weeks i. E; yesterday again my bike stopped after misfiring and was not getting started.
I don't know what the hell is wrong with service people. If they don't know to resolve the problem then they should say to visit other dealer.
But no, they say it will be ok by the next service.
Now am damn frustrated with the service given to me. The worst company i have seen which doesn't know to fulfill the customer demands. I would never suggest anyone to buy this bike.
