Question about 2006 Bajaj Pulsar 180 DTSi UG

1 Answer

Bajaj Pulsar stops after some KMs

Dear Sir, I have a strange problem with my Pulsar 180cc UG3 (40000 KMs done). Apart from this problem there are no issues with my bike at all. Let me explain you in detail. After driving my bike for some time; vacuum gets created in the fuel tank so the petrol doesn't flow to the fuel pipe from the fuel tank. Earlier I used to face this problem once in every 2-3 days (Around 70-80 Kms run) but now I face this problem 2-3 times a day (30-40 Kms). I took out a simple solution of this problem. I open the fuel tank for 6- 10 seconds whenever I've to go somewhere and the engine performs well after this. To add to the problem; if I drive by bike and then make it rest for 30-40 mins and then while driving back if I start the bike again (Self Start) and forget to open the fuel lid; the bike stops after 500 Meters. At this point I open the lid and the bike starts in 1st go. What I can figure out is that the small hole inside fuel tanks (to rinse the rain water) is blocked so the air may not be flowing in. I checked in with some mechanics but I still face this issue. I tied to clean that hole but its so tiny that I doesn't I guess. I'll tell you about my driving habbits so that you may get some more idea. I fill the petrol from only one petrol pump every time. I fill arount 7- 10 Litres so that I don't have to worry about petrol. I use a petrol lock and always turns it off it after I reach the destination. I never leave it on Reserve or ON state. I changed the petrol lock thinking that the lock may be faulty but this problem still persists. I always kick start my bike in the morning or if I drive it after 4-5 hours. In the morning I drive a bit faster (around 70- 95 Kmph) as I always get late and has to rush to the office :). While coming back from work I drive like I am sitting on an elephant. Very slow, steady and calm (40- 55 Kmph). Please help and suggest me a perfect solution. I am tired of opening the fuel lid time and again, sometimes it is frustrating and embarrassing to do in the traffic. Apart from this my bike has no issue. No performance issue, no acceleration or breaking issue, nothing at all. My 180cc is a very good performer (Provided petrol intake in engine is running perfectly) Please E-mail me @

Hi, Surender you need to unblock the fuel tank vent line if it has one if it does not then you need to unblock the fuel cap venting system drill a small hole in the cap that will allow venting but no fuel escape or replace the fuel cap with a new one for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry. If necessary transport your vehicle to the dealer or shop and have a professional technician take it for a test drive, if it is in running condition, and give you a written estimate of repairs and answer any specific questions you may have about your issue.

My pulsar 150, 16000 kms done. Now the engine getting more heat within 10 to 15 kms . The oil change intervel is 3000 kms

Hi, Anil your engine was designed to run at an oil temperature of 180-230 degrees Farenheight or 82-110 Celcius if your not comfortable with those specifications you can always install an oil cooler otherwise the usual suspects are:
1. Insufficient oil supply, or oil not circulating.
2. Insufficient air flows over the engine.
3. Heavy carbon deposits.
4. Ignition timing retarded due to faulty MAP, CKP, and/or CMP sensors.
5. Leaking intake or exhaust valve.
6. Water coolant low or pump failure.

i have got my bajaj pulsar 150 cc 9 months back, i too faced the same problem. i have taken to the bajaj service center where i have recieved a answer for my question saying that the volves inside the engine either might have bent down or there might be a breakage in that. he also said the engine has to be opened and the volves has to be replaced. some parts like gasket, spark plugs and volve caps should also have to be replaced. to stick back the opened engine we should get used by some paste also. i have get my bike done with that repair and now there is no leakage of the fuel.

I want to buy a bajaj pulsar . Confused between 135 and 220 cc . Heart says 220 cc but mind says 135 cc.Want extreme power but also fuel efficiency . Then 220 cc doen'nt come with valves which makes the...

I speak from experience, I have a 180cc Pulsar, me and my wife both travelled on the 180cc together, we commuted approx. 100km daily and had fuel efficiency of approx 35km/l on the 180cc, I think you might still get about 30km/l on the 220cc, if it is only you travelling on the bike, the 180's top speed(with a bigger front sproket, 17 instead of 15) was about 125km/h(not pussing it in the red)
Hope this help to make up your mind, personally I would go for the 220 if it is speed you want
