I am suffering from a strange problem. I have a pulsar 150 2006 model. Now whenever i try to start it through self start, it wont start. To start the bike everytime, I have to unplug the spark plug and bring out the cable to generate current, I touch cable to engine & on other hand i push self-start button, for few seconds it doesn't show spark but then it start showing spark, so after bike gets start I switch of the engine & put spark-plug & cable back to place & now when I self start, the bike easily starts up, for next 8-10 hours bike easily gets starts through self start but if i self start the bike after 10 hours it refuse to start up & i have to repeat the same procedure again.
