okk bro going to clean the tank also, i will update at evening.....thank u bro for your valued answer.

the below mentioned things if done will get rid of the problem.... also did you remember if by any chance water entered the tank??

Yep... the problem seems tobe with fuel supply only... tell them to clean the carburetor and clean all the fuel lines.... also clean the airfilter.... If you can then go to a mechanic and tell him to check if spark plugs are getting proper current...

abhi how to tell this prob to sc guys?to clean the carb n check fuel lines right na?there is no excess smell of fuel.... excess fuel flow through the free valve located under the carb.......this is bcoz if the bike refuced to start then i will pull the choke is this right abhi?

Is there any excessive petrol smell from bike??

Ok... looks like fuel supply issue to me.. check all the fuel lines and clean the carburetor by opening it...

yes abhi.....nothing happend....

Hello,

Did you tried opening the fuel-lid for 2-3 seconds and then try starting the bike?

abhi,there is no valvoline oil...then castrol gtx(something like that n its 20w50)...i think its better than dtsi oil....again a big problem ..sometimes the bike wont start ?today i changed the spark plug for rs 140,the problem exists...i dont know why am facing this type of big problem...?if it start then there is no missing and the bike goes very well...if i park the bike after riding sometimes when i push the self we can hear the self sound but the bike wont start... i tried pull the choke but nothing happend,there is no prob with self(am curious about the battery bcoz about 10 or 12 times i pushed the self)after about 10 times of self engine started.Abhi whats the reason? the SC guys says its strange...Is the bike need any carburator tuning ?

I am too using Bajaj oil currently. and to say this is one of the worst oil I have used so far. Although I will change this oil at next service, but the engine is very harsh, mileage dropped down..... gear shifts hard problems.... I will change to Valvoline next service.
