Loss of power bike under performing

Picked up a zeal with only 20 thousand kms on clock , all was well until the last couple of week . Bike gives the impression it need to be pushed alot harder . Bike is used as a commuter . Previously would cruise up a the same hill everyday in sixth gear doing about 90kms/hr with no dramas . now the bike struggles up the same hill . Have changed fuel filter and air filter a month or so ago same time oil and oil filter were changed ... any ideas ???????

Which type of engine oil should i use in my Pulsar 150?

I have been using Castrol Active (Grade - 20 W 40) in this bike and have never faced any problems. Do not use the Castrol Power 1. Also get the engine oil changed after every 2500 kms. (get it replaced after 500 - 600 kms during the 1st service and after that change every 2500 kms)

It all seems to be leading to fuel starvation. Have you checked the tank breather is not blocked which can be a small hole in the petrol cap or a tube from under the tank. It could also be a blocked fuel filter. There should be two. One inside the fuel tank under the petcock, another before the fuel pump.
