I have a Bajaj Pulsar 150cc bought in 2007. I regularly give bike for servicing and the running is smooth and in good condition. Suddenly from last month, whenever my bike gets wet in the rain for some time, it runs some distance and then abruptly stops. Then, i need to wait for some time and then retry and retry and finally it would start after 5 mins and again after going for some distance the same problem happens. This continues till 6-7 kms and then it would run without issues. Everytime the bike gets wet, I'm encountering this problem. I never had this problem all these years. I even took to a mechanic shop, but even the mechanic couldnt find the issue. Please help me. I also changed the left spark plug, but it didnt helped me.

Couple of days before it completely got stopped on my way to office and then luckily I found a nearby mechanic shop. When I told the whole story, he instantly told that water would have gone inside the petrol tank.

When we took the petrol from the tank we saw that indeed the water was there and this water was going inside the carb which was creating all the hell of a problem. I gave the bike for servicing and he told that the small hole which is inside the petrol tank, if stuck with dust, would create all this nonsense.

Now the bike is doing gud. Couple of days before it completely got stopped on my way to office and then luckily I found a nearby mechanic shop.
