Bodkin Arrow

My Pulsar 150 (black) is exactly 1 year old, I've done 4200 km.

Now, the problem is the overheating. I can feel the heat on my feet for even a short distance of 4 km it is accompanied by a burnt/charred smell. Replaced oil just a couple of days ago (Castrol) despite this there is excess overheating even in early morning (winter) moreover gear shifts are hard. It seems like there is intense pressure on the engine when I exceed 50-55 kmph. The servicing was done on the last week of December. Please help

I reside in Navi Mumbai.

Significant loss of pick-up and power, Bike struggles beyond 4k RPM where there is increased noise (which usually occours when riding hard). I have not exceeded 60 kmph since I've faced this issue.

Despite servicing it is continuing.

No Modifications done.

No Fall.

There is a dominant burnt smell for short distances.

You sure you got the genuine oil??
You sure svc actually changed your oil?
What model (UG) is it?
Have used castrol activ 4t 20w40 (purchased from authorised dealer)
and its a bad oil, the worst i have found.

Please suspect the intake manifold and suspect for cracks or punctures.

this reply may look strange. . i had this same problem in my pulsar 150. . I checked tappets , clutch plates , oil pumps etc. . Still the prob was on. Svc guys said overheating was normal but i felt the burning smell too while i was standing in signals. . . Finally my friend asked me to try fully synthetic oil . I ve tried motul 300v FS everything was Disappeared but still i dono wt was the reason. . To test this i switched to castrol mineral - oh man ! That prob came again . Now i'm oly using fully synthetic having no problems at all. . Gurus put ur knowledge wat would be the reason ?

Bodkin Arrow - What's the color of your spark plug? Good & clean pics on the bottom part of spark plug will help us understand what's going on within the engine.

Also check for wrong fitting of spark plug, Yes it might be inserted correctly but the grooves might be worn out or pushed with pressure resulted in slanting of a spark plug....Results in straining of engine at mid level RPM...Also fuming of engine as if burnt smell arises....

Hope this helps...
Remove both of the spark plugs and insert it slowly ensuring the fitting is tight inserted without pressure.
