Friends, this issue has popped up recently in my factory fitted CNG kit (suzuki cultus 2008 vxr efi). After 90 seconds from ignition start, the petrol mode should switch to CNG mode. But it has a fault now. Either the engine stops (fails to continue in CNG mode) or it switches to CNG but the engines stops in low speed or while shifting to lower gears. The general mechanics referred me to suzuki company workshop. Company advised to replace a piston inside the CNG kit.
Please guide me where can i get this piston from. Suzuki company doesnt have it in their spare parts inventory.
