i had the same problem with my avenger 200. what i used to do was to tilt the bike, like what we used to do with old scooters and then start with choke on.. this has worked for me.. next time may be i can try opening the lid..

Thanks dude. but I was looking forward to find out the root cause of the problem, and I think I found it out.. It was a block in the pressure regulating hole in the tank cap.Originally posted by nitro66 View Postnothing to be worried about. Just open tank lid. wait for 5 second and start your bike. I think sunlight or heat create some vacuum so the fuel not able to pass.
Thanks all experts who took this thread seriously and put in their valuable suggestions...
Moderators, thanks for approving this, my problem seems solved.
If this thread needs to be closed. then please..

Mine is Pulsar 150 DTSi UG2. I park my bike office parking area and I cover it to prevent paint fading. when I take my bike in the afternoon it goes off after 150 - 200 meters run as if there's no fuel. I have to pull the choke and kick 10-15 times to start it after that. Once it starts, there's no problem.
This problem doesn't shows when I start my bike in the morning ( My be because there's no sunlight heat during the night).
Also there's no problem if I park my bike in a shed during the day time.
please advice a remedy. Is it because of fuel vapourization from carb. due to sunlight heat?
please help.

yes! if the breather hole is blocked, must open the fuelcap to adjust the pressureOriginally posted by aargee View PostWhat I assume is, the breather hole should be covered up (dirt/dust probably) & when the fuel tank is exposed to hot sun, the fuel evaporates & some amount of pressure is formed within the tank. So once you open up, this evaporated fuel escapes adjusting to the regular atmospheric pressure. Just a wild guess!!!

Once I open the fuelcap a minute berofe starting, the problem gets solved. There must be a block in the fuel cap hole compromising in pressure adjustment. I will check it today..

Ya. there's a breather hole in the lid..but the water drainer should be under the tank.. Thats what I dont find.. The only attachment is the sensor for fuel level!!Originally posted by aargee View PostWhoa!!! Are you sure? IMO, this is breather hole for the air to seep in & not for water to seep out!!!

Can you elaborate on this one pls? Are you saying that you're unable to start if you open up the lid before starting the vehicle?
thanks dude

But I idnt fint the hole for water seepage!!! Is it in the fuel cap?

So pressure variation is the problem...!!!!Last edited by aargee; 01-19-2011, 09:14 AM.

Originally posted by ch.madhur View Posti have also face this problem quite no. of time, and the simple way to start the bike is to open the lid/cap of tank for some time & let some gas to escape and then try again,
if then also it doesn't work-try to use kick few time
(for P200/P220-take the bike to some speed and start it using shifting up/down gear-it definitely works)
you are right neal, this thing is told by few guys to me also and i notice its true

It also prevents air lock when exposed to sunlight so ensure that the drain hole including the pipe is all clean and then you wont experience that problem anymore

Thats right, But 2 of my screwdrivers snapped when I tried it myself. Thinking of taking it do Bajaj Authorised SCOriginally posted by neal_wreakz86 View PostFirst of all change your mechanic. A mechanic who cannot open screws should be ashamed of himself you dont need lathes to that just remove the coil and put and avenger's coil or you can rewind your coil with a higher gauge wire. It doent require any rocket science an experienced mechanic will leave no scope for you to complain.

But unable to unscrew the pulse generator screws. So I went to a mechanic. He said it's better get help from a lathe workshop
Wonder why he said so..??!!!
