Query Approved.

maybe you are running lean
try adjusting the air fuel mix

1) Check the state of ur engine oil
2) Check if your air filter is choked
3) Check if ur carb is clean and also check the A/F ratio
4) Check for blockage of fuel lines
5) Check your spark plugs for carbon deposit, if so clean the tips and put them back

Go through the above checklist and get back here. Most prolly, i guess u have had a bad service. Most of the free services, they just wash ur bike and hand it back. Stay with ur bike while it s being serviced.

Agreed check carborator and fuel T and check the tank cap whether its allowing air to pass or not...

yeah dude..i had the similar..issue..my p180 ug 3 is 350 km old ...i had this issue around 100km on the odo...as u said if u rip the throttle..it makes a sound as if sombody is blowing air in the water pipe..and it use to swtop and it will take ages to start...but now i got this solved..i shook the byk very badly and the next min it used to start...i called up the mech and he said that itz air logging in the tank..and preventing petrol from flowing freely....he checked the fuel pipe..he blowed some air into it...and the problem vanished from then....

and remeber to fill petrol atleast 2 litres....i was confused by this earlier...when i shook the byk i heard the sound of the petrol...but it doesn't start that petrol remains at the farend of the tank...near the leg guard....and also checked the book ..it was mentioned that 1.2 litr is unusable

its only an issue with your carb...get the float pin setting checked.
the air funda has not workd in my case. i need to see it to beleive it. dont blindly belive these roadside mechs. a 180 is a very simple machine

P.S. plz change the name of the thread. AS an owner of this fantastic machine i find it offensive.

the carb should not get dirty just at 3.5k kms still you can get it checked .

yeah ur right dude..this is wonderfull machine...n regardin that air funda..i also first didnt blieve it,but whtz the matter it got solved thtz enough for me..n till now no probs to complain....n he was not a gully mech he was a bajaj service center guy......no diff between tham though

yeah ..the carb shouldn't get dirty in the stock conditions.....worthy tryin it

just one thing to ask....my byks undergone 1st service yesterday...but before that..one day..my mind gone mad and i took it to 80k/hr coz other byker was ,messin with me with RX--(dont know which one).. n i don't like to b messed with those street honkers....one rip and the biker vanished then realised and removed the hand from the throttle..
WT a JACkass!!! ...after all itz the matter of my bikes condition..!!

now will it make any difference to engine....as i have rode it past 65 as mentioned in the book..!!

I plan to fix it myself if possible.
so need some help.
1.Engine oil is perfect.Just 200km old.
2.In order to clean the air filter,should i remove the whole air box on the rh side of the bike or just the rectangular vertical cap?Also the ss guys put some kind of oil on the foam element.What oil should i use?Using what should i clean up the air filter?
3.The mechanic cleaned the carb once since this prob has occured.If i wanna clean it again, is it ok if i rinse it with petrol?
4.There is no blockage in fuel lines.The fuel flows freely.
5.Regarding spark plugs, how can i remove the carbon deposit without damaging the plug?Is there any special cleaning fluid available?How much should the gap between the electrodes be?I have stock plugs installed.

There is a lot of fluctuation in acceleration.Also there is a [I]dhup-dhup[I] sound coming from the exhaust.When I accelerate and then close throttle while in motion, the RPM falls like usual but while the RPM falls, this sound occurs.


Also, about the rich/lean mixture, there's a screw for tuning that. I dont know whether its a fuel-screw or an air-screw.How many turns from the point of complete tightening should i set it to for a perfect mixture?

Road rage is bad!
Do not race on the streets man!Its not safe.

Can u tell me where exactly this pin is?
will i have to remove the whole carb to set the pin?

Check the plug , may be fouling , or check the air filter too.
