+1 someone please post a snap i need this one cleared before i touch the carb

.

It is present on the carburetor heat insulator. (Heat insulator is present between the engine head and the carburetor.)
If this tube is removed when the engine is idling,the engine shuts off.

I will try to post the picture by tomorrow evening.

tried removing that pipe thing and blocking from my thumb. It was sucking air in pulse form,when i open its end engine RPM seems to be rising,isnt this tube going from carb to the engine upper part connected with chrome pipelines(or whatever they are called

).tuned my carb at 1.5 turns from fully closed. BUt the problem still remains the same of that missing fuel problem at inclined road and a pillion where i cant pull in 2nd gear and if i try to accelerate slightly more it feels like fuel is no more. i cant sleep due to this. Somebody plz help

Saurabh that pipe goes to sec. air injection to carb...also did you clean / replace air filter and spark plugs ?

i have to change the air filter and spark plug was changed 8K kms before. can this missing fuel problem be due to airfilter/sparplug ???

Yes a clogged air filter can dramatically reduce performance and fuel economy . You should change it , doesnt cost much though 150 bucks..just for info i am telling this ...an engine needs air , fuel and spark for its running lack of any one will result in poor performance and efficiency . So before tuning carb i suggest you replace air filter

thnx rohit but carb tuning is not my priority as My mech told me that my carb is perfectly set by watching color of spark plug few days back.,my main concern is that missing fuel behaviour at inclined road where i have to use 1st gear all the tym to climb that road which was not the case earlier. and if i accelerate it refuses to pickup and behaves as fuel is finished.

Clean the pilot jet of carburettor before doing any other thing, your pilot jet seemes to be blocked or there is water fixed on the jet, which is causing missing on opening the accelerator. A slight water on the jet will cause missing, so clean the carburettor and tank if it has water and then touch any other part.

Thanks Shoeb and Sibun for on time response.here is an update.visited mechanic yesterday and he did the following.opened head and cleaned the carbon deposits inside ports and Combustion chamber. replaced valves. tuned carb. dint changed engine oil.he suggested for 200kms run in, once done, oil will be replaced.because of run in, i dint tested bike for performance at higher speeds. on lower rpm too, bike was getting much heated than it used to be.according to mechanic, this behaviour is normal after replacing valves.has somebody experienced it?

Don't lug the engine just ride it normally as you used to ride. Avoid riding at RPM greater than 6K for initial 50kms because you want a thin carbon layer to be deposited.
Change the oil and then do some high speed runs so that the valves will seat properly.

After about 400-500 kms tune the carburetor again and then only check the mileage.

@All
I have seen some people to rip their bikes as soon as it is out of the showroom and on the other side some over-care their bikes and lug the engine heavily. Suppose it is mentioned in the manual to ride below 4k RPM,he will ride in 5th gear at low speeds to that the RPM never goes beyond 4K.
The key here is not to stress and lug the engine too much and at the same time not to over-revv it. Ride normally without any hurry,change the gear when needed to prevent lugging the engine.

I know it is very difficult to hold yourself from testing your new dream bike's potential but these few initial hundred kilometers will determine for how long you will be able to enjoy your bike.

what about extra heat?

If the mechanic has lapped the valves with the seats correctly then there is no problem. Most mechanics just replace the valve and forget to re-seat them thinking that the valves are new.
Usually the mixture gets lean as a slight layer carbon starts to deposit hence the heat.

When was the engine oil replaced last time ? If the engine oil has done over 1500kms or 4 months(whichever is earlier) then replace it as soon as possible.

Did you get the carburetor cleaned ? When was the air-filter replaced last time ? If the RPM-Speed in not matching then replace the clutch plates also.
Getting all this work at this mileage will not only ensure good FE and smoothness but will also increase the life of the engine.

Mechanic did valve grinding.engine oil has completed its 700kms.air filter replaced yesterday. Carb was tuned for richer mixture. will get it retuned after a week.

while you are at it, get the air filter cleaned as well (i have experienced this missing/jerking behavior due to both a bad air filter and a blocked jet in the carb which had a tiny piece of thread from the waste cloth used my mechs) get you fuel petcock and tank cleaned too as it may have rusty deposits (if cleaning the air filter and carb dont fix it, try with a new air filter)

i wish someone could teach me to clean the carb as i dnt trust other mech for this.i will change airfilter tomorrow. i had changed my spargplug 8K kms earlier along with airfilter,may be the plug is not fully compatible.

Update: My RPM seems to be varying too much within 1 hr of ride.in the beginnng it was 1500 and suddenly it rose upto 3K :O,it must be affecting my FE badly. This thing makeing me doubt my sparkplug,what do u say guys ???

As usual VEEDOL showed its worth, and i think your search for better oil ends here. I have not yet tried Super swift on my extreme.

So which oil are you using now ? Till date which was the best oil you have used in xtreme ?(other than Super Swift)

And regarding Runnin in of new engine, i will tell you all an interesting story, tommorrow.

Waiting for this.
