[Resolved]  Honda Motocorp — Cb trigger's cylinder kit damaged in 20000 kms

Address:

Alappuzha, Kerala

I have purchased cb trigger on may 2013 and completed all free services after free services, done services in regular intervals also changed engine oil in service centre in out area. At 15000km bikes has shown some discomforts i met with the company service centre and changed carburator and starter and now at 20000 km bike shows same complaint engine missing with low mileage, mileage fall, down to 35 from 55 and company is claiming 60 km/l.
When i consult with the showroom service centre they are saying that i have to change the cylinder kit which is coasting around 4000rs i have already spend more than 10000 rs for this bike with in this one year..is it fair that a new bikes cylinder kit damaged with in first 20000km...
I am fedup with this bike this is the worst bike which i have ever used...
