There are two filters - centrifugal filter and mesh filter.
You need to open the right side engine cover to access them.
Centrifugal filter is round in shape and is visible once you open the engine cover.
The mesh filter is placed horizontally and we need to pull it out to see it.

I have purchased my bike in 2009 and red alloy wheel version in Okhla,Delhi.Bike was running smooth till 2016 October(50000 kMs) when one fine day on my return to my house in Noida the engine seized 2kms ahead of my destination.I dragged it all the way to my home as being late nigh no local mechanics were open/available.I did an online search and found a local mechanics in sector 49 Noida who offered to take my bike from my home for repair.After 2 days he handed over a bill of 11K and told me the full engine was overhauled and bike will run like new.The assurance lasted only for a day or two as i noticed smoke bellowing from my silencers and i went to him again,He told me that it is minor and some oil might be left in the silencer owing to the smoke.However after a week again i went for a checkup and found out the engine oil was at minimum level.He told me again with minor adjustments he will repair it.Again after a day i got back my bike and after 10 days of running(average 5kms daily) my bike again broke down in the middle of the road.I blasted the mechanic and asked him to repair it free of cost and he did so.

I was running my bike after but my confidence was down and the engine sound too was different and i never drove it for more than 6kms as i feared it will broke down anytime.In february 2017 i finally decided to give a last try at a authorised Hero service center at Uppal Motors Bhangel Noida.The service guy quoted me 11k for half engine and 14k for full engine repair.I got full engine done with a total hit of 14K approx(Bill attached).He asked me not to speed more than 50km/h for upto 500kMs when the next service shall be done.I am driving my bike but i still feel something amiss and not like my original engine sound.

Request the experienced bikers community please help me out by please checking the service bill provided as i do not want to sell my bike and have already invested around 25K for the repair work.

Thanks do they need to be replaced?

Centrifugal filter is to be opened and cleaned and the oil filter need to be replaced only if the mesh(around 50 Rs) is not in proper shape else you can clean and use it again.

Thanks, but you have to open the engine cover to access the filters right? Will there be any problem if the cover is opened and something happens? And what oil to use?

First thing either you should have gone to a trusted mechanic or to a good hero svc. Don't leave your bike at their mercy. I always over see the work done on my bike. The price of head work is quoted in the bill which could mean that they have not changed head, only did lathe work on engine head for replacing valve guides. Are you sure that they have used original guides? Many of the lathes are not having the tool for replacing original guides and grinding it. They simply replace with bigger duplicate ones. If duplicate ones are used you will never get the true feel of your much loved bike.
