ya ur teuly right man!! i could have ignored him in the streets ..but on that he appared on the brodaer road..and "ek makki bhi nahi tha" us din..that lured me!!

it wont make any difference dont worry..i bit of ripping is good ..

i was searching for the bike run-in and maintainance thread but cant find it.
theres no problem with hitting high rpm's once in a while. its good for the bike and top end actually.

@pavan:
1Q: do you park your bike outside in the sun more often?
when you feel your bike is choked and feels outta fuel, open the fuel-cap and blow into fuel tank, close it, and start after 5 secs. let us know if the problem is still found?

EDIT:
Q2: how much fuel do you usually have in the tank. the same happens when you have 5+ ltrs of fuel? fulltank?

doesn't req to remove the complete air box just remove the side panel & air box cover.

use fine steel brush and rub on the tip to get rid of those carbons.....to check the gap use feeler gauge and set accordingly...


the sound is common for all the 4st bikes that occurs due to some drop lets are injected in to the cylinder due to the heavy suction which used to sputter...........

the screw which u found is the air screw to adjust the air which feeds slow speed jets. regarding the turns get it done with the expert but there is a simple idea just follow this but not a 100% accurate to tune a bike.

keep the idle high tight the air screw to max when u feel that bike may die (sound reduces)

loosen the screw now again as the engine beat increase and starts to spin fast at one point even if u loosen the screw the beat feeble and fade out.

u should have heard a fast beat that is the point of engine working with correct fuel & air flow this takes time to observe.

best of luck

Hi,

I own the same bike, as others said try the rich air settings. One major thing, does this happen after ur bike has been in the sun? If yes, open the fuel tank for a few seconds, as hot air which cant escape through the air pipe gets collected in the tank. This should do the trick.

I cleaned up the spark plug on the left side, i could not get the one on the right side out. The bike is not jerky any more.But i noticed a problem.
Whenever i accelerate the bike, it runs just fine. Suppose i started the bike, put it on the 1st and took off, shifted to 2nd and third as i used to do normally, after gaining some speed, when i leave the accelerator, the rpm drops as usual but there's this dhup dhup sound which is quite unusual.the sound is not as loud as a misfiring spark plug but the rpm doesnot drop smoothly.there is some sound. Wha is it? I took my bike to a mechanic, he poured oil in the silencer and revved the bike. The oil sprayed out from the outlet of the exhaust as well as from a hole near the front footrest.


Now there's this sound, plus i ripped the bike till 94km/hr, and there was a thick white smoke comin out from the silencer.Was this smoke from the burning of oil from the silencer or my piston rings are fried???

Also, does the air screw or the fuel screw control the A/F ratio for idle mixture or even when the throttle's opened?

Is the screw air screw or fuel screw on p180ug3's carb?

as i said b4 the sound is due to the suction for which u required fuel & air........i some bikes the throttle will not close fully & the engine braking will not be great as there is still fuel & air is being supplied even after the throttle is closed.............

i think the oil poured by ur mech is to find is there is some water stored in the silencer & the hole near the front foot rest........... the hole is provided to drain the water if it enter which is not so effective in pulsys

every carb has the air screw but the placement differs. if im right the air screw is used for idle mixture only coz during full throttle there will be more fuel compared air coz the needle gives way & the fuel enters............

this is my theory let me see wat the other gurus say regarding this.......

time to check for any valve damage

I recently changed my bike s exhaust and the mechanic exactly did the same before he fixed the brand new silencer onto my bike.

No, piston rings arent fried, the oil the mech put into the silencer is being fried

There is only one screw. No air screw, No fuel screw separately.

No, there is a seperate screw for that called the Idle screw.

Can u please post a pic of the idle screw location and the other screw location.Is the idle screw the one that supports the semicircular disc to which accelerator wire is connected?

I managed to clean both the spark plugs.is there a need to adjust the plug gap?the bike is still jerky again.it jerks as if its running out of fuel though i'm running on almost full tank.also there's a clicking sound coming whenever it jerks.the sound is as if something is slipping and then snapping back to place.i'm quite frustrated now.the silencer too is now making sounds unknown to me.please guys help.no mech nearby is able to help.they just don't get what the problem is.i took my bike to the ss.it ran fine when the ss guy rode it.so he said there's nothing wrong with it.but on the way home,same thing.all jerks.i asked an experienced mechanic.he said he got wha the prob is.but i was apprehensive givin him my bike.his words were "coil magnet side ka one way gear atack raha hai.uska hi ye clicking sound hai."i'm running an avenger coil.but i've been running on it since the last six months.has this mod caused this problem?

Exactly! Thats the idle screw.

Update:

So finally frustrated with the bike, and NO REPLIES about the sound from the bike from u guys,
i finally took my bike to the SS.
Those guys inspected the bike, and replaced both the spark plugs.The bike's sounding perfectly normal but accelerating like never before.I think while playing with the air/fuel screw,i tuned the carb to a slight richer mixture.!!
