Did you clean the plug before riding the 10-15km ?
If you did, then again clean it and increase half a turn i.e. 180.. max go to 4 turns.. if not buy new plugs and check again.
Firstly pl try to clean out the petrol tank and fill from a different pump

Bro, i will get new pair of plugs and will do 4 full turn and update the result. I have just checked the fuel and they are clean and no residue the tank appear clean and basically i always filled fuel from the same petrol pump. Just out of curiosity, does the plug still look like im on lean?

just because there is no residue doesn't mean its not adulterated.. the white tip says there is a problem.. maybe lean or bad fuel or a bad spark plug.
You still haven't answered what I asked.. Did you clean the plug before testing ??

Sorry bro, i forgot to mention, i just used some cloth to clean the electrodes. But the color as and base remains the dark brown and outer tip remains the same whitish grey color
Also could you please tell me what is the exact model of pulsar UG 4.5 recommended spark plugs? Have been surfing like crazy but can't find a proper answer. Also should i use identical plugs for both RHS, LHS ? How about bosch plugs?

Because i want to do the 4 full turn taste with shiny new plugs. My carburetor is Mikuni BS 29 just in case

Oh man, that's not how a plug is cleaned.. you at least need a wire brush or fine grit sand paper to remove that white layer and re-gap the plug to 0.7-0.8mm
the stock plug is champion rg4hc , and yes you can use same on both sides.
I do not know what plugs are sold in bangladesh, but NGK plugs are also good
NGK Partfinder Catalogues
CR9E (normal)
CR9EGP(platinum)
CR9EIX (iridium)

There are fake plugs that might look shiny but would cause problems.. You are better off going to the asc and picking up a set of stock new plugs unless you know someone locally who can help you source the right aftermarket plugs which match the oem plugs.

Yeh that's the carb on the pulsar

I believe i ended up buying fake plugs. Because the plug says its 'champion RG4HC' but it came in a box which was loose and almost open, showing bajaj logo. I have a picture here, let me know if champion plugs are sold as bajaj parts! [ATTACH]149827[/ATTACH]

I have cleaned spark plugs and as advised from full tightened position with 3 full turns and a very little more to the loosened side. Now thats how the spark plug looks and bike engine dosent feel much hot now. Still i wish to hear what you think guys. Thankz in advance . [ATTACH]150169[/ATTACH]

Now, that's a good color or should i say its perfect .. now check your mileage using tankfull to tankfull method(tankfull- ride 100km - tankfull).
Put on some more km and let us see. This looks good enough though, maybe another 1/4 turn either way will hit the sweet spot.. but first put on a few more km and report back with mileage and your observations if any.
And do keep an eye on the engine oil level.

All Bajaj pulsar owners can share this thread for experiences.

problems recently with my bike

Model -Pulsar 150 DTSi ES 2004.

odo- 40000kms

Problem- Electric stater

After purchasing the bike in 2004 this is the first battery that i hav purchased. The previous one did close to 25000 kms .Very recently I got my bike an Exide9MX battery from an authorised dealer.
After 7 days the battery goes low and the self was of no use. Took it back to the dealer and he charged up the battery at no cost. Again , all worked well. But ,again the bike refuses to start when its a bit close.
When I ride harder and for more hrs then only the self start works. I never use self at early morning ,for that reasoon I hav kick start. But I think the problem is not with the battery there is something else. Though the battery is under warranty, so no worries abt that but I dont knw if the stater is ok or not. The horn is better as new which says that the battery is giving juices to the horn. Bike needs to be heated to use the self. So, what may be the problem?
Is the stater gone kaput? or its jst normal with this model?
