I had bought activa 125 2months back
The scooter was fine there was no issue in the vehicle, as soon as i did my service from "sai honda" the following are the issued happend
1) i did my 1st service on 1000kms after 2 days of servicing there was a significant drop in the economy and the fuel gauge was not indicating properly, i went to the service centre but they hust dodge me saying it happens after the service it wont happen after few kms, but the problem stil exist ...anyways
2) during the 2nd service they were so pathethic the guy just forget to put the engine oil cap.
After we straight went to work, on the way i reliase the scooter was jerking i park a side just to see whats wrong and there was oil spiliage engine was about to seize, on top of that engine makes noise and the acceleration has gone low
I want your immediate concern regarding this issue
