I just got a new pair of spark plugs for the Pulsar 220 DTS-Fi yesterday. I was informed about arrival of a new replacement set, a couple of weeks back by Auto Service, Bangalore.Why were the spark plugs replaced?
I had personally reported the below issues:
-Cold start problems, multiple cranks needed
-Change in firing patterns and exhaust note (audible changes)
-Engine requiring higher idling rpm setting than the base range of 1200-1400
-Engine flaming out suddenly and unexpectedly during normal running, and then needing a full reboot to start again
Besides me some other users had reported similar issues.
Although the replaced set is a same part number as the original one, its purpose would be only to prevent the same issues repeating for some more time till a permanent fix is found. I was told earlier that the spark plugs had developed micro holes on the electrodes.
This issue only bring out one question.. Why did Bajaj choose to use the same spark plug from the 180cc platform? The 220cc engine obviously would need a better/different design characteristics spark plug due to hotter and more combustions. So lets wait and see what happens next on the spark plug front.

I was told be VEnkat that one of the plugs is the same as on 180/200 and the other one is 2 pts hotter ...
2 hotter! I find that hard to believe - one maybe, but two!?
Anyway, what I was going to say, the only way plugs are going to fail when so new, what to speak of pitting! is if they're crap plugs. Best thing you can do is replace with the equivalent NGK plugs. Or Denso.
