I bought Mehran Limited Edition (Aug 2005) about a month ago. Its going well and does about 120 Kms with 40 Kg Cylinder.
The problem is that when I start it on CNG in the morning it vibrates badly and makes a noise like tik-tik. So I pull the chowk untill it warms up. With chowk there is no noise.
I got it checked from a mechanic, he said that this sound cant be eleminated.
I checked and found that if I press the filter the noise stops but on release it starts again.
What may be the wrong with it?
