TVS Motor Company — low mileage on apache rtr 160

Address:

403507

Hi, i own a rtr 160, a 2013 version.

Hi im having a serious problem with my rtr 160. My mileage has suddenly dropped by 9kmpl.
I have tried everything in my knowledge to solve the issue but in vain.
I have cleaned and retuned my carburettor, replaced the spark plug and air filter element, lubricated the chain and checked the tyre pressure too. I have run my bike on fully synthetic oil since the second service and i drain the oil every 4500kms. But the mileage remains the same at 36kmpl, i used to easily get 45kmpl earlier. Even the mechanics are not able to figure out what the problem is. My bike has done a running of 51000kms.

Please help me out as to what is to be done to solve my issue.
