Last 8 years I am using this bike, milage arround 40 to 55 only. company says that 70 km milage per liter. and also no spare parts available on store. other all facilities is nice. so that I am using this bike last years. I ad one advertisement for sale, someones call to my number, finally they said that to give rs.10000 for this bike, I am very sad for this fuel proble. all engine related works completed. I dont know why this problem?
