Hero Motocorp — Hero passion xpro bike engine faulty

Address:

Pune, Maharashtra

I had purchased the passion xpro bike in 2014 april its from 1 and half years following issues i am facing
1 - the bike average is too low - - - 35km / litre
2 - engine heats up too much even with small rides
3 - no permanent solution or change in sparepart / engine itself by hero purchase / maintenance vendors.
